MODEL HAT/FPFREEZE PROTECTION VALVE

FREEZE PROBLEMS?CALL THE GURU1-800-288-GURU

OPERATION:A thermostatic element senses ambient temperature

and if this falls below 40°F (4.4°C) the valve modulates

open allowing water to flow by the sensor. The valve

will remain open as long as the water flowing by the

sensor is less than 40°F (4.4°C). However, when the

water flowing by the sensor becomes greater than

40°F (4.4°C) the valve will close. The valve is fully

open at 35°F (2°C).

APPLICATIONS:HAT/FP (Freeze Protection) valves are ideal forprotection of piping, valves, fittings, pumps, condensatesystems, safety showers, fire lines, spray nozzles,freeze sensitive equipment, or as backup protectionon traced systems/equipment. The "AA" model isrecommended for draining condensate fromcompressed air systems.

ADVANTAGES:Typically freeze protection is effected by crackingopen manual bleed valves. This method is at bestrisky. Human error or plugging of partially crackedvalves annually accounts for large amounts of freezedamage to expensive equipment. HAT/FP valveseliminate this type of problem by automating freezeprotection, reducing water consumption, andeliminating damage and down time. The unique ram-type plug and seat provide reliable, tight shutoff longerthan any other design available. All HAT/FP valvesare 100% factory-tested and covered by a 36 monthprorated warranty.

DESIGN FEATURES:• Stainless steel body, fittings, spring and plug

• Corrosion resistant - Long service life

• Narrow temperature band

• Compact, low mass - Fast response

• Ram-type plug for reliable tight shutoff

• Downstream actuator for greater sensitivity

• Sensitive to temperature only

• Unaffected by pressure variations

• Easy installation with pipe wrench

OPERATION:

Under normal operating conditions, water passesthrough a virtually unobstructed 1" NPT-F or larger teebody, allowing this valve to be used in higher flowlines. When the fluid temperature approaches freezing,and freeze damage is imminent, the thermal actuatorlocated in the fluid stream modulates the valve open.When the makeup water temperature returns to thesafe range, the valve then modulates closed, reducingwaste water losses. Due to the actuator’s placementin the fluid stream, this valve is unaffected by ambientair temperature, and opens only when the water is indanger of freezing, being fully open at 35°F (2°C), andfully closed at 40°F (4.4°C).

MODEL FPPAUTOMATIC DRAIN PLUG

OPERATION:

The FPP may be though of as an automaticfreeze-out plug with one important difference:The stainless steel FPP cartridge releases itselffrom its body at a pre-set water temperature,rather than being forced out by the tremendouspressure of expanding ice. This provides almosta full one inch bore to rapidly drain a coolingsystem before damage can occur. Resetting andrearming the FPP prior to refilling the system iseasily accomplished by simply reheating thecartridge and utilizing the slotted actuator feature.With the unique built-in check valve (on Models Tand FL only), it's possible to replace the entire FPPwithout draining the system.

APPLICATIONS:

• Water cooled compressor heads• Exposed water lines• Tanks and related piping• Exposed chiller lines• Sump and reservoir protection

ADVANTAGES:

• Will not accidently trip or dump• Easy installation• Completely mechanical - No electrical or air

connections• Models T and FL can be maintained or

replaced without draining system• Cartridge can be reinstalled with simple

twist of wrist• Rapid draining• Easy system refill

DESIGN FEATURES:

• Senses only water temperatures• Long service life• Easy maintenance with interchangeable

cartridges• Several body styles available for various

applications: 1-1/4" NPT tee, flanged tee,and compressor head

• Release temperature of 47°F or 40°F

HEAT ACTUATED TRAP/REVERSE ACTING

OPERATION:When the water temperature rises above safelimits, and a danger of scalding exists, the thermalactuator modulates the valve open. A small sampleof the water from the pipe system then flows pastthe sensor. If the water is above the acceptablerange, the valve will continue to modulate openuntil the overtemperature water is eliminated.When the makeup water temperature returns tothe safe range, the valve then modulates closed,reducing waste water losses. The HAT/SP opensonly when the water exceeds safe limits. TheHAT/SP-105 is full open at 105°F and remainsopen until water temperature is 95°F or below.The HAT/SP-115 is full open at 115°F and closedat 105°F and below.

APPLICATIONS:Solar radiation or overheating caused by steam orelectric tracing can cause extremely hightemperatures at the point of use, resulting in asafety hazard for plant personnel. When installed insafety showers, eyewash stations, and otherlocations exposed to the same source ofoverheating as the system, the HAT/SP will beheated just as the pipe system. The valve will opento establish flow until the overtemperature water iseliminated and it will then modulate closed.

ADVANTAGES:The HAT/SP valve continually senses andautomatically bleeds excessively hot water fromsafety shower/eyewash systems. Protection isprovided with minimal water consumption. Theunique plug and seat design offers the mostreliable, tight shutoff available. All HAT/SP valvesare 100% factory tested and covered by a 36month prorated warranty.

MODEL HATHEAT ACTUATED TRAP

DESIGN FEATURES:

• Compact, low mass - Fast response• Corrosion resistant - Long service life• Stainless steel body, fittings, spring and plug• Ram-type plug for tight reliable shutoff• Eliminates live steam loss• Narrow temperature band• Downstream actuator for greater sensitivity• Orifice design limits live steam loss• Operating temperatures unaffected by

pressure• Wide choice of set points• Easy installation with pipe wrench

OPERATION:

The HAT valve responds only to temperature. Aftercondensate forms and cools to near the setpoint, theHAT valve modulates the flow to maintain a constantcondensate discharge temperature. HAT valves arewide open at start-up for rapid venting and initial heat-up. HAT valves are self-draining after shutdown, toeliminate freeze damage. Typical setpoints include105, 125, 180, 210, and 240°F (41, 52, 82, 99, 116°C).

APPLICATIONS:

Therm-O-Tech HAT (Heat Actuated Trap) valves areideal for replacing conventional steam traps onwinterization tracing, instrument tracing, condensatereturn system freeze protection, tracing for processesunder 150°F (65°C), and other applications requiringin-line flow control based on temperature.

ADVANTAGES:

Since HAT valves discharge condensate well belowsteam temperature, live steam losses are eliminated.For temperature sensitive applications, such asinstruments or certain processes, the reducedtemperature available for tracing simplifies operationsand eliminates overheating problems. The uniqueram-type plug & seat provide reliable, tight shut offlonger than any other design available. HAT valvesare 100% factory tested and are covered with ourstandard 36 month warranty & service policy to furtherreduce maintenance cost.

MODEL HAT/RA-LPFOR COOLING WATER CONTROLHEAT ACTUATED TRAP/REVERSE ACTINGWITH LEAKPORT

TEMPERATURE CONTROL PROBLEMS?CALL THE GURU1-800-288-GURU

DESIGN FEATURES:• 100% factory tested

• Stainless steel body, fittings, spring and plug

• Compact, low mass, fast response

• Corrosion resistant, long service life

• Most clog resistant design available


• Modulation throughout temperature range

• Sensitive to fluid temperature only


• Easy to install with pipe wrench

• Operates in any orientation

TYPICAL APPLICATIONS:Cooling water control for:

• Compressors• Engines• Heat Exchangers• Welding Equipment• Electrical Equipment• Molding Equipment

OPERATION:The HAT/RA-LP is installed on the cooling water outletof the equipment as an afterflow controller. At start-up, the valve is closed except for its control leakage,which allows a small flow so that the actuator insidethe valve can sense the changing equipmenttemperature. As the outlet water temperature increasesto within the operating range of the HAT/RA-LP , thethermal actuator modulates the valve open. If thecooling water temperature is above the acceptablerange, the valve will continue to modulate open allowingadditional coolant flow. As the outlet water temperaturefalls slightly, the valve then modulates toward the closedposition, reducing flow. This modulating actionmaintains a relatively constant outlet water temperatureeven as the cooling load changes.

ADVANTAGES:The HAT/RA-LP continually senses cooling water outlettemperature and automatically modulates to maintaindesired temperature. Optimum equipment temperatureimproves efficiency, reduces wear and conservescooling water. Therm-Omega-Tech valves aredesigned around our exclusive Thermoloid ® sensor/controller which is the most advanced and reliablethermal actuator of its type available today. All Therm-Omega-Tech valves are factory tested and calibratedto assure unsurpassed accuracy, reliability and quality.

VALVE ENGINETHERMALLY ACTUATED DEVICEFOR CUSTOM DESIGNS

CALL THE GURU 1-800-288-GURU

valveengine 5.01

OPERATIONThe Valve Engine responds only to temperaturechange, and is unaffected by operating pressure. Thevalve will proportionally vary flow rate with temperaturein a repeatable, precise manner.The ìValve Engineî is essentially a complete operatinginternal assembly for a self - operating temperatureactuated valve. The assembly includes everythingexcept the valve body. This compact, economicaldesign lends itself to simple integration into manykinds of equipment and devices.The heart of the engine is a solid-to-liquid phasechange thermal actuator. The actuator contains aThermoloidÆ compound which changes phase froma solid to a liquid as the temperature increases. Asthe phase change occurs, the volume of theThermoloidÆ material changes significantly, with theliquid volume greater than the solid volume. Since theThermoloidÆ is essentially incompressible undernormal operating loads and it is sealed into a rigidactuator housing, only a piston can move and extendas the volume increases.

This motion is used to open and close the valve.

ThermoloidÆ compounds are available in manytemperature ranges to cover most applications.

APPLICATIONSï Automatic thermostatic bypassï Thermostatic flow controlï Hydraulic bypassï Freeze protectionï High or low temperature reliefï Thermal relief valve for pumpsï High temperature safety shutoffï Thermostatic drain valveï Thermostatic cooling water controlï Thermostatic condensate drain

ADVANTAGESThe phase change and resultant motion occurs overa narrow temperature range. This property allowsprecise control of a device at a specific temperaturewith no significant effect outside the chosen controlrange. In fact, the properties of these thermostaticmaterials are so precise that are they used as primaryreference standards by ASTM for instrumentcalibration. Equally important, the reliability of theseactuators is very high, which has resulted in theirapplication in critical aerospace, military and manyindustrial applications.In addition to the actuator, the Valve Engine alsoincludes a stainless steel return spring, valve seat ando-ring plug. Seal materials and valve capacity can betailored to each application

DESIGN FEATURESï No outside power source is requiredï Rugged, compact designï Reliable and repeatable performanceï Wide choice of temperature rangesï Alternate contruction and seal materials availableï Extremely shock and vibration resistantï Can be used in pressure or vacuumï Custom mounting configurations availableï Compatable with most liquids, gases, or vaporsï Sold seperately or in a valve bodyï Also available in reverse acting (opens on rising temperature) Call factory for details.

OPERATION:

When the shower or eyewash is activated, thepressure drop on a diaphragm opens the steam controlvalve (V-3). Water and steam flow are establishedinstantly heating the water and condensing the steam.A mixing valve (V-1) then blends the heated water withcold water to produce an output of 85°F water.Additional valves keep the system preheated, freezeprotected and scald protected. Steam valve remainsclosed should water supply be interrupted.

DESIGN FEATURES:• Uses existing plant steam and water supply• Provides 3 to 30 GPM of 85°F with an inlet water

pressure of 45 PSIG• Easy to install on any existing shower or eyewash/

shower combination• Compact, lightweight design easily supported by

pipe connections or factory mounting kit• Plant steam and water never mix...uses compact

hi-capacity heat exchanger• Maintains constant 85°F output regardless of inlet

water temperature (between 40°F and 85°F)• Preheated to provide instantaneous 85°F water• Freeze and solar overtemperature protection

included• No insulated tanks or expensive recirculation

systems required• Operates on typical plant steam pressure (45 PSIG

recommended)• Self-purging...no need for elaborate drainage

system• All components are in-line field serviceable• Durable fiberglass enclosure can be readily

removed for servicing• Union connections allow for quick and easy

installation• Conforms to OSHA and ANSI recommendations• Unaffected by sudden cold water pressure drops• Trap on steam inlet included

REDUNDANT CONTROL:Level 1: (V-1) This valve mixes heated and cold water

and compensates for the pressure dropthrough the heat exchanger and associatedpiping.

Level 2: (V-2) This valve opens when heater outflowtemperature reaches 105°F, bypassing waterback into the steam inlet to limit the heatexchanger output temperature.

Level 3: (V-3) Senses flow from V-2 and modulatesthe steam valve closed. Additionally, if watersupply is interrupted, the steam valve staysclosed until water flow is re-established.

Level 4: (V-4) Senses final water temperature andshuts off steam valve if water temperatureexceeds 85°F.

* THE NEED *An instantaneous and reliable source of tempered water for a safety shower/eyewash system using a hot andcold water supply.

* THE PROBLEM *Conventional mixing valves are unsuitable as the means to provide tempered water at safety shower/eyewashstations. These valves by nature have the property of shutting off entirely if either the hot or cold water supply isinterrupted. This is dangerous and unacceptable for safety shower/eyewash systems where cold water must beavailable under all circumstances. To meet today’s OSHA and ANSI recommendations you must have a systemwhich can respond safely to both hot water and cold water supply failures.

* THE SOLUTION *The Therm-O-Mix Station/WWM . It’s WM-1 mixing valve acting in concert with it’s unique PWM-1 pressuresensing controller assure that cold water will flow to the shower and eyewash even if no hot water is available (aslong as the cold water supply is not shut off elsewhere in the system).This is accomplished using completelymechanical, self operating controls. No electricity or air required.

TRIPLE REDUNDANT SAFETY CONTROLS

PWM-1 Pressure Sensing Controller:Therm-Omega-Tech’s unique diaphragm operated valve actuatorsenses the water pressures on both the hot and cold water inletconnections. If hot water pressure is not present at the mixing valveinlet, this actuator will override the mixing valve and allow full flow ofcold water. If no cold water pressure is available at the mixing valveinlet, both the mixing valve and the diaphragm actuator will close offthe hot port to prevent dangerously hot water from flowing to the shower/eyewash system.

WM-1 Mixing Valve:The primary temperature control device is Therm-Omega-Tech’s three-way mixing valve. This valve is designed around our exclusiveThermoloid® sensor/actuator that automatically and accuratelyproportions the water flow in response to outlet water temperature. Thismixing valve simultaneously modulates both the hot and cold waterinlet ports to provide 85°F water to the shower/eyewash system. TheThermoloid® sensor/actuator is the most advanced and reliable thermalactuator of its type available today.

V-4 Safety Override:This control element senses the final water temperature and will positionthe PWM-1 pressure sensing controller to close off the hot water portof the mixing valve if the final water temperature is above 90°F.

MODEL HAT/WWM-RFLUID TEMPERING VALVE


OPERATION:The hot fluid connects to the side, pass throughconnection on the HAT/WWM-R valve. Thisconnection is never regulated so it always remainsopen regardless of temperature or valve position.

The hot fluid flow then passes over the thermalactuator which controls the cold fluid inlet port fortempering. If the hot liquid temperature is above thevalve setpoint, the cold fluid port is open. As the hotliquid cools, the valve automatically modulates toreduce the cold fluid inlet flow. If the hot fluid is belowthe specified temperature, the cold fluid inlet port isclosed, since no additional cooling is required.

HATWWMRA.2/99

APPLICATIONS:Can be used in applications where the fluid must betempered, for example, the discharge of condensateor boiler blowdown with cooler water before piping toa sewer or return system.

ADVANTAGES:Controls cooling of hot fluid to desired level beforereturn to system or discharge to sewer. Flow throughdesign facilitates discharge. Automatic temperaturecompensation conserves tempering fluid.

TYPICAL USES:• Condensate discharge from steam traps

• Condensate return headers

• Boiler blowdown drain lines

MODEL HAT/WWMMODEL HAT/SWMWATER TEMPERING VALVES


APPLICATIONS:The THERM-O-TECH HAT/WWM and HAT/SWM valvescan be used in any application in which a constant outflowof water at a specified temperature is desired. Thesevalves, like any mixing valve, must be installed with checkvalves on both hot and cold inlets for the HAT/WWM and atleast on the cold side for the HAT/SWM. Pressure reducingvalves are recommended on HAT/WWM installations inwhich system pressures are likely to vary. The PRV’sshould be adjusted to approximately 10-20% less thanaverage system pressure for accurate and constant outflowtemperatures. In some installations throttling valves may beused in place of PRV’s. These throttling valves should beset and locked for safety.

The HAT/SWM can be used to trace critical components that muststay warm, but below steam temperature at atmosphere (212°F or100°C).

OPERATION:This self-contained valve is designed around a thermalactuator that automatically adjusts the steam or hot watercomponent to temper outflow water to the specifiedtemperature. The device is factory set and is not useradjustable, and is therefore tamper-proof. The valve isdesigned to yield outflow temperatures within a given range.If water is inadvertantly not turned on, the actuator turns offthe steam flow at the set point temperature, preventing thetypical "hose full of steam" problem. Typical set points (°F)available are 90, 105, 125, 145, 155, 180 & 210. (32, 41, 52,63, 68, 82 & 99°C)

MODEL STVM VALVESILENT TYPE VORTEX MIXERFOR STEAM/WATER MIXING

OPERATION:Therm-Omega-Tech’s STVM valve uses uniquevortex technology for silent operation. Duringoperation, cold water enters the mixing valveand forms an inner vortex that moves from theinside out, while incoming steam forms anopposing outer vortex that moves from the outsidein. Mixing occurs as the two vortices collide,thoroughly mixing and heating the water to thedesired temperature.What’s especially remarkable about vortextechnology is what you don’t hear - the banging,popping, and crackling noises that come fromordinary mixing valves. That means there’s noneof the racket that can add stress to the workenvironment, and none of the cavitation that can

ADVANTAGES:Because of the unique vortex flow characteristicsinside the STVM valve, it is capable of mixingsteam and water without the usual noise andvibration associated with other types of mixers.As a safety feature, the thermal actuator in thevalve outlet is designed to turn off the steam flowinto the valve if the cold water flow into the valveis interrupted. The entire internal operatingmechanism(AKA cartridge) of the STVM valvecan be quickly and easily removed as a singleassembly by simply unscrewing the valve cap.This allows easy cleaning and service withoutremoving the valve from the line. The Unique flowcharacteristics of the vortices inside the valvecreate a scouring action that together with specialcoatings on the cartridge element minimize theeffects of mineral deposits on valve operation,assuring increased service life even under adverseconditions.

OPERATIONThe EMPC uses advanced technology to sim-plify and reduce cost of complicated controlfunctions. The development of this deviceparalleled advances in digital electronics andmaterial science. There is simply no equal forpower, speed, reliability or cost.

The EMPC can be fitted to any standardTherm-Omega-Tech valve or may be adaptedto other control devices manufactured by anynumber of suppliers (consult factory for rec-ommendations). Process variables aresensed with standard transducers. This infor-mation is then processed and converted toprecise position information. The simplifiedelectronics of the EMPC goes quickly and di-rectly to the setpoint without overshoot or hunt-ing. Adjustment of controller power factor al-lows the EMPC to operate precisely withinvery narrow control bands, making it unlike anycontroller or positioner previously available.Auto tuning then becomes more accurate andprocess specific.

THERMAL ACTUATORSSOLID-LIQUID PHASE CHANGE ACTUATORS

FOR CUSTOM DESIGNED ACTUATORSCALL THE GURU1-800-288-GURU

ACTUATOR.10/97

1-Actuator assembly includes return springs and rod ends; unit contractsin length up to several inches when cooled. 2,6-Conventional mediumoutput actuators. 3,12-Actuator assemblies including integral heater forremote control. 4,10-Actuator assemblies include integral valve cagewith valve seat, spring flange, seal grooves. 5,7,14-Long, thin actuatordesign; stroke nearly equal to actuator body length. 8,9-Typical miniatureactuators. 11-Conventional low output actuator. 13-Actuator withproprietary seal design for high reliability in extreme conditions. 15-Actuator with integral fluid sensing connections with over 2” stroke and200+lbs. output force.

OPERATIONThe thermal actuator is filled with Thermoloid® material,which changes phase from a solid to a liquid and expandsas the temperature increases. Since the material isessentially incompressible and encased in a rigid housing,only the piston can move and extend as the volume of thematerial increases. This motion can be used to operate awide variety of devices. When the Thermoloid® materialcools the volume contracts and allows the piston to retractif a return force is acting on the piston. The piston will notnormally retract unless a return force is present.

The phase change and resultant motion occurs over anarrow temperature range. This property allows precisecontrol of a device at a specific temperature with nosignificant effect outside the chosen control range.

APPLICATIONSThe precise motion of these thermal actuators can be usedto operate a wide variety of devices, limited only by theimagination of the designer. Temperature actuated valves,switches, latches, clamps and control devices are typicalapplications.

ADVANTAGESNo outside power source is required to produce motion.Temperature change alone can be used to operate a device;e.g., open or close a valve, move or release a latch, operatea switch. Because the Thermoloid® material operates inboth the solid and liquid phase, each of which are essentiallyincompressible, load changes on the piston (within designlimits) have little or no effect on operating temperature. Thisis in contrast to vapor-filled or liquid to vapor phase changedevices which are generally very sensitive to load changes(changing the load on these devices, e.g., changing springtension, is used to change the operating temperaturerange).

Since the operating temperature of solid-liquid phasechange actuators is determined by the Thermoloid®material properties (i.e., melting and solidificationtemperatures), the operating temperature is extremelystable, repeatable, and accurate. The properties of thesethermostatic materials are so precise that they are used asprimary reference standards by ASTM for instrumentcalibration.

DESIGN FEATURES• Long, powerful stroke• Rugged and compact• Reliable and reproducible• Wide choice of temperature ranges• Not effected by shock or vibration• Can be used in pressure or vacuum, liquid or gas• Custom mounting configurations available• Can be made from most machinable materials• Typical temperature change for maximum stroke: 10F°

to 20F°(5 to 11C°)• Start to stroke temperatures from about -30°F to 300°F

(-34°C to 149°C) or higher

APPLICATION PROFILE #1INSTRUMENT ENCLOSURE VALVES (HEATING*)

Application: For the control of inside temperature of instrument enclosures or analyzer housings that are heatedvia steam or hot fluids.

Purpose & Background: Instruments/analyzers installed out-of-doors are exposed to adverse conditions and arecustomarily enclosed in insulated boxes to protect them from physical and weather damage. Many installations requirea certain inside temperature be maintained to prevent freezing, control viscosity or to maintain instrument calibration.Two systems are commonly utilized to provide such protection:

Electrical Trace ; using an electrical heat tracing cable. Normally provides excellent temperaturecontrol with integral thermostatic control but is costly to operate. Not suitable in many hazardouslocations and traced equipment is subject to freeze damage during power outages.

Steam/Hot Fluid Trace ; this is normally accomplished by dressing a copper or stainless steel tubearound the inside of an enclosure or by installing a coil or finned tube heating element inside anenclosure. Steam, heat transfer fluid, hot oil or water and even hot condensate from a steam main iscirculated through the loop or heater providing the source of heat to protect the instruments. Thisnormally provides excellent freeze protection but when uncontrolled can result in overheating ofthe instrumentation.

The Therm-O-Tech TV/SC-I valve was designed to provide safe and economicalcontrol of the heating medium to regulate the internal temperature of the enclosure.

The most common installation ofthe TV-SC-I valve is shown inFig. 1 : The actuator of the valveis inserted through the enclosurewall utilizing the integral bulk-head fitting provided with thevalve. In this arrangement feederconnections are external to theenclosure.

BULLETIN APPL.5/96

Fig. 1 Fig. 2 Fig. 3

Due to the increased use of tubebundles, where heat trace linesenter the enclosure with impulseor sample lines, a short bodydesign is required to allow allconnections to be within theenclosure. This can beaccomplished using the Therm-O-Tech TV/SC-A valve design asshown in Fig. 2.

The ITCH Assembly(Instrumentation ThermostaticallyControlled Heater) comescomplete with steam coil,mounting bracket, TV/HATvalves, and tubing bulkheadfittings, and may be mountedeither internally as in Fig. 2 , orwith external steam supplyconnections. (Fig. 3)

APPLICATION PROFILE #2MANUAL CONTROL OF STEAM TRACING vs.

AUTOMATIC CONTROL USING US/A OR TV/SC-A VALVESEXAMPLE:A winterizing steam tracing system in a plant located in Philadelphia, PA consumes about 500 pounds per hour of steam.

This system was manually turned on when danger of freezing temperatures approached (mid-September) and turned off inlate Spring when danger of freezing had passed (mid-April). Total yearly operating hours are 5,088:

212 days x 24 hours = 5,088 hours in potential freeze season.

The plant's steam cost is $ 5.00 / 1,000 pounds of steam. The operating cost of this system can be calculated as follows:

COST OF MANUALLY OPERATED SYSTEM:

500 pounds per hour x 5,088 hours x $ 5.00/thousand pounds = $12,720.00 per winter season.

COST OF AUTOMATICALLY OPERATED SYSTEM:When using THERM-OMEGA-TECH ambient sensing TV/SC-A or US/A valves, steam tracing will be turned off automaticallywhenever ambient temperatures rise above 45°F (other closing temperatures can also be specified). Based on U.S.Weather Bureau data for Philadelphia, steam will be on for only 2,895 hours each winter.

500 pounds per hour x 2,895 hours x $ 5.00/thousand pounds = $ 7,237.50 per winter season.

SAVINGS REALIZED PER WINTER SEASON BY USING THERM-OMEGA-TECH VALVES:

$12,720.00 – $ 7,237.50 = $ 5,482.50 per year

SIMPLIFIED PAYBACK AS R.O.I. ( RETURN ON INVESTMENT)Assuming an installed cost of $ 500.00 for the THERM-OMEGA-TECH valve to control the above system, the simplifiedpayback for this application is:

PROTECTION OF UNINSULATED* WATER LINES

In a "Resupply System", a pressurized source replaces water. Freeze protection is provided by removing the colderwater from the system, and allowing warmer resupply water to modulate the valve closed. Larger valves will not wastewater, and it is impossible to oversize. The rate at which water must be removed can be calculated as follows:

1) GPM =

Where: GPM = Gallons per minute of water flowA 1 = Pipe flow area, ft2

A 2 = Exposed pipe surface area, ft2

tw = Temperature of resupply water, oFta = Minimum air temperature, oFd = ID of pipe, ft

The valve flow coefficient (CV) required to remove water at this rate iscalculated as follows:

2) CV =

Where: GPM = Gallons per minute of water flowCV = Total required CV of valves∆P = Pressure drop across valves (PSIG)

(If valves discharge to atmosphere, ∆P = PS where PS is supply pressure.)

Example: Freeze protect a 125 foot long run of uninsulated 2" pipe whenthe minimum air temperature is -15oF. The resupply water is40oF minimum, at 60 PSIG.

From the pipe data chart, for 2" schedule 40 pipe:

A1 = 3.36 sq. in./144 = 0.023 ft2

A2 = 0.622 ft 2/ft x 125 ft = 77.8 ft2 also: tw = 40oF

d = 2.067 in./12 = 0.172 ft ta = -15oF

1) GPM = = 9.6 GPM 2) CV = = 1.24*

Choose the valve or valves required to give a CV of 1.24 or more. The use of several smaller valves will provide

redundancy. Valves must be installed as close to the far end of the pipe as possible. Any side branches must be

individually protected.

*For properly insulated lines, use 25% of the CV indicated as an approximation of required CV

Water Supplies for Safety Showers & Eyewash Stations

There are many concerns in industries equipped with safety shower/eyewash units related to watersupply quality, OSHA and ANSI safety requirements, and providing safe and comfortable watertemperatures for employees if a shower/eyewash must be used.

1. Water Quality: As a general rule of thumb, if it is safe enough to drink, it is safe enough toshower with. An area of concern is insuring that the water supply is free of any sedimentbuildup and any bacteria that might have developed in the standing water supply. ANSIstandards recommend that all emergency shower/eyewash devices be checked on a weeklybasis to ensure proper working conditions, confirm adequate water supply and to flush anysediment/bacteria out of the system. Many shower manufacturers offer units with pipelinestrainers or recommend they be installed on a dedicated water supply line.

2. Water Capacity: Plumbed emergency shower/eyewash equipment requires a line size thatwill provide adequate flow. The chart below shows typical water pressure and supplyrequirements.

Most of these are clearly understandable. Further clarification is offered for two of the items under"Other Considerations".

3. Delivered Water Temperature: 60° to 95°F (16° to 35°C). In most cases the high temperaturecondition is of critical concern and a high inspection area for OSHA ; however, low temperaturehazards are also a growing concern.

a) Overtemperature/Scald Protection: Supply lines or shower units installed outside aresubject to solar heating with internal water temperatures reaching 150°F (66°C) and above.Likewise, indoor units and lines may be subject to high ambient temperature conditions fromprocess, steam or condensate lines. This overtemperature water must be purged from thesystem to prevent scalding.

Relationship of Time and Temperature: Studies1 have demonstrated that there are two criticalfactors which determine the risk of a burn injury occurring: the temperature of the material andthe length of time the skin is exposed to the temperature. For water, the following chart providestime/temperature relationships required to cause a full-thickness (3rd degree) burn.

Remember! Normal safety standards dictate a minimum of 15 minutes washdown in the shower!

The most common device used for overtemperature/scaldprotection by shower manufacturers and retrofitted byusers is a self-contained temperature activated valve, suchas the Therm-Omega-Tech HAT/RA or IC/RA designs.

The internal sensor/actuator operates over a 10°F (5.5°C)temperature differential, with the valve being fully closedat 95°F (35°C), starting to open and allowing a small waterflow when fluid temperature is sensed at 96°F (35.5°C),and increasing to full flow if temperature reaches 105°F(40°C) or above. This purges the hot water from thesystem, to be replaced by the cooler water in the supplyline.

Valves are normally installed at a low point in the station(see typical piping layout) to insure:

1. Full station and system piping are purged of hot water2. Valve discharge will not reduce available flow to shower or eyewash unit.

b) Low Temperature Shock/Hypothermia Protection: Many facilities are now considering theeffects of low water temperature in relationship to the length of time a person will shower, or thecombined effects of hypothermia and shock to the victim due to extended exposure to cold water(Remember: 15 minutes or more is required).

A 1993 case relates that a power plant employee was splashed with a hazardous solution. Followingplant safety procedures, he at once went to the nearest shower unit, started a full body shower, andalmost immediately jumped out of the shower due to the cold water. Knowing the potential dangerfrom burns, four fellow employees forced him back into the shower, holding him in place for therequired 15 minute washdown; by then, he was unconscious and in shock.

Many manufacturers are addressing this concern by offering a number of variations of temperedwater supply systems. These range in size and design from electric or steam water heaters to hot/cold water mixing assemblies.

In line with the needs within the industry, Therm-Omega-Tech's Constant Temperature WaterSupplies are available as either a unit that mixes hot and cold water supply like the Therm-O-Mix ®/WWM or a unit that utilizes plant steam to indirectly heat the supply water like the Therm-O-Mix ®

Station . Both have redundant controls for safety, and are self-contained; no electrical connectionsare required. The most common temperature requested is about 85°F (29°C); not warm enough toopen the skin pores and not too cold to deter usage. Information on both the mixing valves and mixerassemblies are available from the factory or your local Therm-Omega-Tech distributor. Therm-Omega-Tech can also custom engineer recirculation loop systems for servicing multiple safetyshower/eyewash stations.

4. Freeze Protection: The second item under "Other Considerations" refers to freezeprotection, mechanical and/or electrical. Many shower manufacturers offer heavilyinsulated and electrically heat traced shower designs. In some areas, electricaltracing cannot be used safely (due to explosion hazards), and potential poweroutages could well result in freeze damage.

A few manufacturers provide backup freeze protection on traced units by theaddition of mechanical freeze protection valves while others (and many users)depend only on freeze protection valves equal to the Therm-Omega-Tech HAT/FPand IC/FP designs.

The HAT/FP, like the HAT/RA scald valve, is a temperature actuated device; inthis case, operating over a 35° - 40°F (1.7° - 4.4°C) range to enhance waterconservation.

The valve starts to open when sensing a fluid temperature of 35°F (1.7°C) or less,closing when the resupply water temperature reaches 40°F (4.4°C).

APPLICATION PROFILE #5THERM-OMEGA-TECH HAT vs CONVENTIONAL STEAM TRAPS

OPERATING COST SAVINGS

The THERM-OMEGA-TECH HAT valves provide substantial savings when compared to the cost of operating conventionalsteam traps. The HAT valves sense condensate temperature and open to allow flow only when the condensate temperatureis below the setpoint, well below saturated steam temperature. The condensate forms a liquid seal ahead of each valve preventinglive steam losses. Also, the sensible heat in the condensate between steam temperature and the HAT discharge temperatureis used for heating.

Most properly functioning conventional steam traps have inherent live steam loses: at least 2 lbs/hr. for inverted bucket traps, andover 5 lbs/hr for disc traps. Actual field studies have shown that live steam losses of disc traps increase considerably with time inservice, with loses of 20 lb/hr after less than one year of service being not unusual. Losses from other types of conventional trapsalso increase with time, but usually less than loses from disc traps.

For this example, we will use 2 lb/hr of live steam loss for conventional traps in good condition and compare this to HAT valves which have zero live steam loss. Further, HAT valves achieve additional savings by discharging condensate atreduced temperature. These additional savings can be calculated based on the value of the heat content at varying dischargetemperatures.

COMPARE OPERATING COSTS FOR TYPICAL SYSTEM:One hundred 3/8" steam tracers (50 to 75 feet long)

CONCLUSION: A typical steam tracer system using THERM-OMEGA-TECH's HAT valves can save at least$222 per valve each year.

Based on an average cost of $97 each for the THERM-OMEGA-TECH valve and neglecting installation labor, thesavings will provide a simplified return on investment (R.O.I.) of 230%:

R.O.I. = $222/$97 = 2.3 or 230% or Payback = 5 months




STEAM TRACING BASICS*

Heat tracing is used for liquid-containing pipelines to prevent the liquids from freezing or becoming too viscous.With pipelines containing gases, heat tracing prevents gas components from condensing.

Heat tracing will normally be required when:

• The lowest ambient site temperature will be below the freezing point of the liquid carried in thepipes. An exception must be made for underground water-pipes installed below the ground frostlevel. Examples of liquid lines requiring heat tracing are: phosphoric acid, molten sulfur, glacialacetic acid, benzoic acid, cresol, naphthalene, phthalic anhydride, sorbitol, p-xlene, and water.

• The liquid becomes highly viscous at ambient temperatures. Examples are: certain crude oils,fuel oils, polymeric materials, waxes, bitumen and tar residues, and caustic soda liquor.

• The gas carried in the line has a dewpoint above the ambient temperature and, condensation ofliquid from the gas is undesirable. Examples are: fuel gas in oil refineries where the liquid causestrouble in the gas burners; natural gas containing moisture that may cause freezeup of controlvalves or even the whole system; compressor suction lines (liquid is harmful to compressors); andH2S/water vapor (causes corrosion on condensation.)

In winterizing practice, water lines are insulated in an effort to avoid tracing. However, there is always a heatloss from insulated lines. If the liquid cooling resulting from this heat loss cannot be tolerated, heat tracing willbe necessary.

If there is no heat tracing, the line may have to be disassembled, with associated high costs and long shutdowntimes.

The length of a traced line is quite variable. It may be a few feet in a process area, a few thousand feetbetween offices and the process area, or over a hundred miles as in the case of underground lines carryingcrude oil or fuel oil.

Still, steam tracing is commonly used because there is a surplus of low-pressure steam available in mostplants.

Since steam has a high latent heat, only a small quantity is required for a given heating load. Also, steam hasa high film heat-transfer-coefficient, condenses at constant temperature, and flows to the point of use withoutpumps.

The simplest method of external tracing is to wrap copper tubing around valves, pipe fittings and instruments.This procedure is unsuitable for horizontal runs because steam condensate collects at low points and mayfreeze during a shutdown. (THERM-OMEGA-TECH, INC., as well as most engineers, recommend thathorizontal runs be traced by strapping a single run of copper tubing to the bare underside of the pipeline.There are different means of insulating and increasing the thermal efficiency of the trace.)

It is essential to ensure that the trace lines are self-draining.

The length of a single trace tube (from steam supply valve to steam trap is limited by the pressure drop in thetrace. The trap should have a condensate drainage capacity to match the heating load. At a steam pressureof 100 psig or higher, the length of a single trace should not exceed 200 ft. If the steam pressure is lower, atracer length of 100 ft. is recommended.

APPLICATION PROFILE # 6HOT WATER TRACING SYSTEM

APPLICATION:

Some chemical products must beheated to an optimum

temperature aboveambient temperature, but arealso sensitive to overheating, e.g.:

formaldehyde.

THERM-OMEGA-TECH's HAT/SWM valves can be used to provide a convenient, economical,reliable and effective hot water tracing system. Steam and water supplies are all that must beconnected to the valve.

At an eastern specialty chemicals plant, it was required to maintain formaldehyde lines at about100°F. Lower temperatures would affect product quality, while higher temperatures would cause theformation of formic acid and other undesirable side products.

The solution was to install THERM-OMEGA-TECH's HAT/SWM-100 and HAT-100 valves whichtogether provide both temperature control and backup safety high limit control. Approximately 100psig steam and 50 psig water were piped to each HAT/SWM valve. The outlet from the valve thensupplied the 3/8" tracer lines on various formaldehyde process piping. At the end of each tracer linejust before connection to the return system, a HAT-100 valve was installed. After the system wasstarted-up, the water temperature at the outlet of the HAT/SWM was approximately 100°F, exactly asthe system design specified. As the safety backup, if for any reason the tracer temperature at thetracer end exceeds 110°F, the HAT-100 will close off to prevent overheating. In this particular case,the customer chose to recycle the heated water to the cooling tower sump, where the water wascooled for reuse. A pump drawing from the cooling tower sump supplies water to the HAT/SWMvalves.

In addition to the HAT/SWM and HAT valves, additional system protection and reliability was achievedby installation of THERM-OMEGA-TECH's HAT/FP valves at key locations and low points. TheseHAT/FP valves provide positive freeze protection to system components and piping in the event of afailure of the steam supply, which could happen if the boiler or its controls fail. The HAT/FP valveswill drain the water from the system at 35°F to prevent freeze damage.

APPLICATION PROFILE # 7UTILIZING HOT CONDENSATE/FLASH STEAM

FOR AUXILIARY HEATING

The superintendent of a mid-size steam plant supplying a centralized steam distribution system took a unique approachto solving two problems on the system.

The first problem was a back pressure build up in the condensate return system due to mechanical-design steam trapsdischarging at close to steam temperature. This resulted in high temperatures in the return, with a two phase flow of hotcondensate combined with flash steam, pressurizing the return and surging within the condensate flash tanks. Theresulting high temperature/back pressure greatly reduced the capacity of steam traps throughout the distribution system.In several cases it reduced the heat output of some equipment, and increased water-hammer problems in steam feederlines.

A second problem within the distribution system was the lack of adequate space heaters or unit heaters in a number ofwork and storage areas, even though steam and return lines were run through the area.

The unique approach to solving both problems was to utilize the hot condensate from drip stations to supply steam/hotwater unit heaters for auxiliary heating, controlling the hot water/condensate discharge from the heater with the THERM-OMEGA-TECH's HAT valve (Heat Actuated Trap). The design of the HAT valves allows the user to select the actualoperating temperatures of the HAT valve maximizing recovery of usable heat (ie: open for discharge at 150°F; valvecloses on a 10°F(5.6°C) rise - no flow at 160°F(71°C).
