Series DC70 Performance.For performance with standard “Y” type cooling elements
refer to model DC70YH10AC6 page 7. Suitable for
compressor air aftercooling up to 2500 SCFM and 14 bar
air pressure.
Series DC70 Technical Data.Refer to model DC70YH10AC6 page 6. Other types are
available including units fitted with “U” type cooling
elements. Consult sales for details.
VERTICAL DISCHARGE TOWER TYPES
Features • Series DC70 and VT2041 vertical discharge tower
type heat exchangers were developed for use in large oil
cooling and air aftercooling applications. The VT series are
among the largest capacity standard oil cooling packages
available.
• These units feature single fan vertical discharge vane
controlled air management systems which reduce noise
levels and eliminate re-circulation of heated cooling air. The
DC70 has a top mounted motor and fan. On the VT2041,
the motor is bottom mounted with a drive shaft to the top
mounted fan. Variable speed fan drives available.
• Both models have a small footprint which means
large space saving on big air cooled applications. The
VT2041 has a foot print of 1600 mm x 1600 mm and can
replace up to 4 of our largest horizontal models.
• For applications such as hydraulic oil cooling in sugar
mills, there exists a large degree of air contamination. These
units can be rigged with ducting to the roof and draw clean
air down and through the cooling elements and thus
eliminate the need to provide expensive air filtration systems.

APPLICATION. These units are most effective as an add on forhydraulic circuits as well as cooling gear drives. The most commonapplication is for hydraulic circuits where there are sudden oil flowchanges with cylinders where flow surges and spikes from cylinderoperation do not allow the use of the cooler in the main circuit dueto the risk of cooler element damage. Use of this type of coolerwith its own separate circuit will avoid this problem. Please contactour sales office to have your application reviewed.
PUMP PRESSURE. Pump delivery pressure to 5 bar. Higherpressure ratings available. Consult factory.
PERFORMANCE RANGE. Heat transfer range is from 0.25 to1.4 kW/°C of ETD. Performance is based on ISO 68 hydraulic oil at30cSt, for other fluids and viscosities please contact our salesoffice. ETD is the difference between the entering oil and thecooling air temperature.
CONNECTION. VCL models are equipped with oil delivery hosefrom oil pump to cooling element. Please contact our sales officeif the pumping head is greater than 10m or you have any specialrequirements. Pump inlet must be flooded.
OTHER MODELS AVAILABLE. We also supply models with othertypes of cooling elements for special applications.
• High performance off-line oil cooling and filtration
systems for cooling hydraulics or gear drives.
• Heat transfer rating from 0.25 to 1.4 kW/°C using
hydraulic or gear oil, contact sales office for suitability with
very high viscosity oils viscosity.
• Internal relief valve for protection against over
pressure or accident.

Air cooled oil heat exchangers for use where the standard aluminium element type oilcoolers are not acceptable for the following reasons.
• Circuits where higher pressures are expected to be encountered.
• Where the atmosphere or the process fluids are not compatible with aluminium.
• Where explosive environments prevent the use of aluminium. Eg :- Coal Mines.
• Where lower internal film coefficient is required for use with higher viscosity oils.
• Where heavy dust laden environments exist. These units have anticlogging type fins

OIL COOLER SIZINGStep 1. Calculate ETD = TOil - TAir
TOil= Temp °C of oil entering the cooler (usually the same as max allowableoil temp.) TAir= Expected Ambient Air Temp °C.Step 2. Calculate kW/°C ETD = kW kW=Heat Load. ETDStep 3. Enter Cooler Performance Tables and select a cooler whichmeets or exceeds the required performance at the required oil flow rate.Step 4. Check pressure drop of the oil cooler selected in step 3. If theaverage oil viscosity is not 30 cSt apply a correction for the expectedviscosity.Computer model selection program available.

D. ESTABLISH THE HEAT LOAD TO BE REMOVED INKILOWATTS. Heat load in the graphs in tables 1 and 2 isexpressed in Kilowatts per degree C at 30°C ETD. Heat load canbe considered to be equal to the inefficiency of the system as apercentage of the power input, less the thermal dissipating capacityof the system.
STEPS IN MAKING A COOLER SELECTION1. Calculate the ETD by subtracting the A Ambient air temperaturefrom B the inlet oil temperature. The heat load performance graphsare based in a ETD of 30°C . If your ETD is other than 30°C makea correction for ETD as follows.
2. If available air face velocity is different than 5.55 m/s upon whichthe graphs are based, a further correction should be made for AFV"C". Refer to Table 3. Read off the correction factor for the AFV youintend to apply to the cooler and correct as follows.
3. With Corrected HL 2 enter Table 1 or Table 2 andselect the cooler type equal to or greater than yourapplication by following the appropriate lines equal toyour oil flow in litres per minute and your Corrected HL2. The number at right hand side of each curveindicates the cooler ID for the cooler type which can beread from the dimensional information on facing page.For larger coolers contact our Sales Department.
4. The Delta P (pressure drop) for the selected coolerat various oil flow rates can be established by referringto the Pressure drop symbols on each curve asexplained in Table 4. These symbols are indicative ofpressure drop with oil at 30 cSt viscosity. Corrections forother viscosities are shown on right hand side of thegraph in table 5. To correct, multiply the pressure dropestablished from the graph symbols by the correctionfactor from Table 5.
5. Most of our Mobile Oil Coolers are available withoptional full flow built in bypass valves set to 2 BAR or4 BAR. Under most circumstances these units may beused as constant bypass valves. Constant bypassarrangement permits higher than rated flow to pass thecooler core under cold start up conditions while allowingmaximum flow through the core when the oil reaches atemperature where a high level of cooling is required.
Operating pressure-21 Bar (300 PSI).Min burst pressure-62 Bar (900 PSI),Max Operating Temperature 180˚C
BASIC INFORMATION REQUIREDA. ESTABLISH AMBIENT AIR TEMPERATURE. This is themaximum air temperature in which the cooler will be operating. Itmay vary depending upon what locality the appliance is beingcalled upon to operate in.
B. DETERMINE THE INLET OIL TEMPERATURE. This is usuallyequal to the maximum temperature considered to be acceptable forthe oil circuit.
C. DETERMINE WHAT AIR FACE VELOCITY IS AVAILABLE.AFV. In many mobile applications the cooler will be placed in frontof existing engine water radiator. Ensure that the increased staticpressure required to draw air through the oil cooler will not reducethe effectiveness of the engine radiator. The performance graphsare based on a AFV of 5.55 Meters per second which is equal to avehicle road speed of 20 kph. Table 6 provides static pressures inPa for the cooler cores.

WATER COOLED EXCHANGERSGeneral information.
Water cooling has many advantages over air blast type heat exchangers. The main limitation to their use isavailability of the coolant supply to ensure adequate heat transfer. In order to accurately select a Dynacoolmodel it is prudent to verify coolant availability including maximum expected operating temperature andquality. Generally 90/10 CuNi will provide the best service in fresh water, sea water and “potable” or even“non potable” water supplies. Stainless steel may be more suited in some applications but not always.Dynacool can offer shell and tube units with SS(316) tubes made to order, contact our sales office for sizing.
• Very low noise ( no noise generated by fan motors )
• Eliminates the fin clogging problems associated with air blast coolers in dusty environments
• Compact overall size when compared to equivalent air blast package
• Better ability to handle cycling pressures
• Heat energy is removed from local area by the cooling fluid therefore not raising the air temperature
around surrounding equipment.

Selection procedureStep 1. Determine the Heat Load.This will vary with different systems, but typically coolers are sized toremove 25 to 50% of the system’s input total maximum power rating.(Example: 75kW Power Unit x .33 = 25kW Heat Load)Step 2. Determine Approach Temperature.Desired exit oil temp°C - Water inlet temp°C = Actual ApproachStep 3. Determine Curve kW Heat Load.Enter the information from above:kW heat load x 25 x Viscosity Correction A = Curve kW load
Actual approachStep 4. Find Curve Operating Point.Locate on the graph the point determined by the oil flow and the curvekW heat load. Any cooler curve above this point will have sufficient capacity.Step 5. Determine Oil Pressure Drop from Curves.
= 0.5 Bar = 1.0 Bar = 2.0 BarMultiply pressure drop from curve by correction factor B found on oilviscosity correction curve.
Performance curves are based on ISO VG 32 oilleaving the cooler 25°C higher than the incomingwater temperature used for cooling. This is alsoreferred to as a 25°C approach temperature.

Series U - Universal PumpsThe Universal Pump Design combines the innovation of the Universeal shaft seal, the rugged simplicity of Haight’s proven “gearwithin gear” internal gear configuration, with the flexibility of a bolt-on, integral Relief Valve assembly. This combination of pumpfeatures offers pump users unsurpassed flexibility to adapt their pumps to changing system requirements.Universal Relief valve - can be added at any time. Can be used for either suction or return.“Gear within Gear” internal design - for nearly 70 years this design has demonstrated if effectiveness in a broad range of applications.Universeal shaft seal - the pump can easily be converted from lip to mechanical or packed gland without disconnecting the piping.
Superior High Viscosity Rotary Gear Pumping FeaturesInput drive at the inner gear provides a built in gear reduction which means less cavitation at standard motor input speeds. The innergear drive also permits a bearing to be provided on either side of the drive shaft and also provides a balanced rotor. These featuresmake the Haight Pump superior for high viscosity pumping. The same features also offer increased life through lower rotor surfacespeeds and better bearing support Most other rotary gear pumps have input drive at the rotor which increases risk of cavitation, rotorwear, rotor side load and higher bearing loads.

For pumping high viscosity mineral oils or vegetable oils. Thestandard models feature cast iron casing and cover components,steel shaft and pinion gear, high tensile iron rotor, self lubricationiron or bronze bearings and Buna-N lip seals. As a general rule,the Cast Iron pump will handle most liquids which have a reasonablelevel of lubricity providing that the liquid is compatible with ferrouscomponents and shaft seal. These models are usually all availablefrom Australian inventory with or without relief valves.
Pressure Ratings. Pressure rating for standard Buna-N shaft sealsis 5.2 BAR for liquids less than 20 cSt and 7 BAR for liquids ofhigher viscosity not exceeding 1000 cSt. It is normal practice forlip seals to weep a small amount of liquid during operation. Forpressures above 7 BAR, special mechanical seals arerecommended. Maximum pressure with mechanical seal is 17 BAR.
*Input power figures are based on use with oil at 50 PSI (350 kPa) pressureand suction at 5 ins HG. When viscosity exceeds the 430 cSt stated above,contact our sales office for revised power requirements.

For Double backed pumps, Hatrided Iron Pumps and CorrosionResistant Pumps contact our sales office.
INPUT SHAFT RADIAL LOADINGAll of the pump configurations shown below are for direct couplingapplications. Where belt or chain drive is used, a special pumpwith overhung load adapter must be used. Consult sales officefor stock options.
VISCOSITY VERSES FLOW RATE AND PUMP SPEEDWith the Haight range of rotary gear pumps there is a directrelationship between fluid viscosity and allowable pump speed.Consult table below. The tableis based on the use of oil withlow levels of abrasiveinclusions. Where fluids withhigh levels of abrasives and/or low levels of lubricity are tobe pumped, please consultour sales engineers. Duringstart up operations for briefpeak periods, a 12% increasein viscosity is acceptable.
ROTATION VERSES OIL FLOWRelief valve type pumps as shown are rigged for clockwise rotationwhen viewed from shaft end of pump. Pressure port will be A andsuction port B. If anti clockwise rotation is required, invert pressurerelief assembly and place it in left side of pump. Port B will thenbecome pressure port and port A the suction port. Non reliefvalve pumps can be run in either direction as delivered.
1. Patented Haight Gear and Rotor for moreefficient Positive Displacement pumping.
2. Three Tooth Contact for smootheruninterrupted pressure discharge.
3. Extra Deep Meshing of Gears reducesnoise and avoids trapping.
4. Outer Rotor Flutes lubricate and expelforeign matter.
5. Special Port Slots wash rotor continuallyduring pumping.
6. New “Bolt on” reversible relief valvesystem for greater bypass versatility andsimple field conversion
7. Pipe Plug type auxiliary ports for tankreturn relief or for extra circuit installations.
8. Top quality ferrous metal bodies arestandard with Gramix iron bearings.

This thermal bypass valve is ideally suited for hydrostaticdrive circuits which require fast warm-up, controlled fluidtemperature, and low return line back pressure. Wheninstalled in the return line of a hydraulic circuit that employsan oil cooler, this device will modulate fluid temperature byeither shifting return line flow through the cooler, or bypassingdirectly to the reservoir. In addition, a built-in pressure relieffunction automatically relieves excess pressure to thereservoir should the cooler become restricted and resultantpressure drop become too high for the cooler circuit.

General Description Three way thermostatic valves usethe principle of expanding wax. A self contained powerelement activates a stainless steel sliding valve whichprovides a positive three way action. All temperature settingsare factory set. Elements are field replaceable, hence valvescan be altered to operate at a different temperature rangeor refitted with new elements of the same setting.During cold start up, total flow is through the by-pass port.Once the fluid temperature reaches the opening point, thevalve begins to open and flow to the heat exchanger supplyport begins. As the temperature rises the valve shifts furtherallowing more flow through the heat exchanger supply portand less to the by-pass port. When the fully shiftedtemperature is reached the valve is fully stroked and allflow is directed to the heat exchanger port.Valves can be used for oil or fresh water serviceHousing - Cast Iron (optional steel or bronze)
O-Rings - Viton (optional, Buna N)Valve - Alloy steel.Applications Three way thermostatic valves may beinstalled for either “mixing” or “diverting” modes of operationand can be mounted in any plane and with port orientatedin any direction.When installing in mixing mode, the valve must be locatedon the cold side of the application. Hot liquid will be mixedwith cooled fluid to discharge liquid at proper temperature.Select a valve with opening point at, or just above, theminimum desired oil operating temperature.For diverting mode, the valve must be installed on the hotside of the application. Cold liquid will be bypassed untilthe system warms up, then flow is directed to the heatexchanger. Select a valve with full shift point at, or just below,the maximum desired oil operating temperature.

Determining The Level Of Heat Load In Oil Circuits.Heat is generated through energy being wasted in the formof inefficiency. Heating in a oil circuit is usually a by-productof motive power which may be some form of engine or motoror a device such as a brake or clutch which converts rotatingenergy into heat energy in the oil.
Another source may be by conduction, convection orradiation from either direct solar energy or any other externalparasite source.
In a hydraulic system, the main energy source is usuallythe input power entering the hydraulic pump from the engineor motor. Some portion of the input power will be wastedthrough inefficiency (friction and pressure losses) and willbe evident as heat in the oil.
The degree of inefficiency in the circuit may be establishedby combined analysis of the known efficiency of the circuitcomponents. More frequently it is established by makingan estimate based on previous experience with the type ofcircuit being considered.
Typical hydraulic system circuits range in efficiency frombetween 80% down to 40% efficient. High efficiency pumpsand motors combined with ample plumbing may deliver upto 80% efficiency. Gear pumps with gear motors or gearpumps with gerotor motors may be less than 50% efficient.
The heat load required to be removed from the system willbe equal to the total inefficiency in the system, less theexisting thermal heat transfer capacity of the system.
So with a circuit estimated to have a power input of 50 kWand an efficiency loss of 30%, there can be expected to bea requirement to cool 15 kW of heat. The components inthe circuit may be able to dissipate some heat so the heatload required to be cooled with a heat exchanger will besomething less than 15 kW.
Power, Heat and Oil Flow Relationships.In the above example we determined that we need toremove 15 kW from a circuit. Now what does 15 kW reallymean in terms of heat. The following are formulae whichcan be used with hydraulic mineral oils to providerelationships between power, heat and oil flow.
L/min = Oil flow in Litres per minute.∆T °C = Entering temp of oil minus exit temp of oil.
Applying formula 1 to the above example with oil flow at100 L/min we get the following result.
So we require a constant reduction in temperature of 5.2°Cin our oil to dissipate 15 kW for 100 L/min.
15 x 34.5 = 5.2 100
1 ∆T °C = kW x 34.5 L/min
2 kW = L/min x ∆T °C 34.5
3 L/min = kW x 34.5 ∆T °C
Oil and Air Temperature Relationships.For the cooling of oil with a air cooled heat exchanger it isobviously necessary to have the air temperature cooler thanthe entering oil temperature. The temperature differencebetween the entering oil and the entering cooling air is calledthe ETD (entering temperature difference).
The larger the ETD the easier it is to cool the oil and bydefinition the smaller the air cooled heat exchanger will be.For purposes of sizing a suitable heat exchanger, it is usualto set the inlet temperature of the oil at the maximumtemperature the system is required to operate at.
Oil temperatures in modern hydraulic systems are preferredto be maintained in the 60°C to 70°C range. Thetemperature of the cooling air will be the ambienttemperature of the air in the locality where the system is tobe used.
Selection of The Exchanger By PerformanceIn this catalogue, performance shown on graphs is usuallyexpressed in kilowatts per degree °C of enteringtemperature difference between the oil and the cooling air(kW/°C).So if the ambient temp is 30°C and the oil temp is requiredto be 60°C, a 15 kW heat dissipation would require a oilcooler capable of 0.5 kW/°C at the required oil flow.
Computer Model Selection ProgramWe provide complete performance graphs for most modelsof our air cooled heat exchangers. However, for accuratesizing we recommend the use of our computer modelselection program which covers almost all of our standardmodels of air cooled and water cooled exchangers. Theprogram operates on most PC computers under Windows.

Noise Levels Of Air Cooled Heat ExchangersIt is a fact of life that air cooled heat exchangers utilise fansto move air through the cooling matrix. High performanceair cooled heat exchangers tend to have dense coolingsurfaces and require relatively high levels of air movementunder static pressure to achieve performance.
We are now publishing measured noise levels for our aircooled models. The measurement is dB(A) @ 1 metre. Forthe record, our method of measurement is to take a numberof A weighted samples at 1 metre distance from the productat prescribed positions and publish the highest noise levelfound among the samples. The result approximates thatwhich an inspector will get when he tests on site by surveyusing AS1217.5.
On any electric air cooled heat exchanger, the noise levelwill closely relate to the speed of the tips of the fan blades.We publish fan diameters and motor speeds so it is easyfor our customers to calculate tip speed. So if you arecomparing our product with one of our competitor’s productsand note his published sound levels are lower than oursthen please compare the fan tip speeds.
It is generally the design policy of Dynacool to use smallerdiameter more efficient fans than our competitors as wellas our SAMS (Superior Air Management System) whichreduces fan diameters. Therefore, we claim that relative tosize and performance our air cooled heat exchangersgenerally have lower noise levels than our competitors.

Air Cooled Exchanger Rigged For Full Status Testing
Application Warnings - Aluminium Cooling ElementsThe furnace brazed aluminium cooling element has thehighest heat transfer efficiency to cost ratio of all oil coolertypes. However, care should be taken in making sure thatthe product is suitable for the application. The followingadvice applies to all makes of aluminium cooling elements.OVER PRESSURE.Never exceed rated operating pressures. Actual failure maytake place at 40% to 60% above rated pressure. Onhydraulic circuits under starting conditions in winter withcold oil, pressure drop figures may exceed 10 times thosecalculated for normal operation. If the hydraulic circuit iscapable of pressures exceeding the cooler rating, a failurewill occur unless a suitable relief valve is provided to bypassthe cooler under these conditions.PRESSURE CYCLING AND SPIKES.Do not install aluminium oil cooler elements in circuits wheresudden changes of pressure or oil flow are likely to occur.Eg:- Cylinder circuits or circuits with oscillating valves. Useof this type of cooler in such circuits will result in rupture ofthe tubes or cracking of tube to header joints. Aluminium isalso subject to fatigue failure under high frequency pressureand/or temp cycling. Bypass relief valves or accumulatorsare not effective against pressure spikes. For theseapplications refer to DP & HL off-line coolers on page 22.HAZARDOUS ENVIRONMENTS.Aluminium has autogenous sparking capability whenimpacted with iron or steel. For this reason aluminium isnot permitted within coal mines in Australia.

Heat Transfer Performance At High Oil ViscosityAir cooled heat exchanger performance and flow capacity will degrade rapidly when oil operating viscosity exceeds100cSt. Consult the chart inside the back cover to establish operating viscosity of your application. Please check withDynacool before selecting heat exchangers for use with high viscosity oil.
MaintenanceContinued efficient operation of the air cooled heat exchanger is dependent on the heat transfer surface being keptclean. In dirty conditions the core element should be cleaned frequently to remove dust and dirt.. Should the fins beblocked with oil saturated dirt, use a petroleum based cleaning fluid followed by water sprayed from a medium pressurehose. Do not use high pressure hoses for cleaning heat exchangers with aluminium fins.
CAUTION. DO NOT USE CAUSTIC BASED FLUIDS FOR CLEANING ALUMINIUM COOLING ELEMENTS.
Installation Of Air Cooled Heat ExchangersPlumbing. Unless approved by Dynacool, use flexiblerubber hoses for connection. The hose size should be thesame size or greater than the port thread size. Solid steelpipes are not recommended as they may place excessiveloads on the core element. If long hoses are used supportthem as close to the ports as possible. Threadedconnections must be fully sealed. We recommend BSPPo-ring face seal type fittings. Should oil be permitted toleak it may cover the core fins and result in the collection ofdust and sludge which reduces cooling performance.Note. Do not fit steel fittings to aluminium ports withoutlubrication as they may bind and damage the port.
Site Location And Environment. Some cooling elementsresist corrosive attack better than others, please consultour Engineering Dept. for details of suitability if a corrosiveenvironment exists. For best heat transfer performance,determine the usual direction of air flow at the site and facethe cooling element towards the incoming air flow withoutrestriction from objects at air inlet or outlet. The unit shouldbe bolted down through the base slots provided.
Positioning In The Circuit. In hydraulic circuits, the coolershould always be positioned to receive return oil from thecircuit. Do not install the cooler in the pressure circuit. Careshould be taken to select a oil source which passes oil at aconstant flow rate not exceeding maximum recommended.If operating viscosity is likely to exceed 100 cSt consult oursales dept. Unrestricted oil flow path must be maintained

DC Electric Motor Connections. Ensure the voltage supplymatches that of the cooler. Wire the supply to the 2 pinconnector with polarity as shown in the diagram providedin the installation instructions. Start the motor and checkthe direction of fan rotation, a decal shows the correctdirection. All fans should pull the cooling air through thecooling element and discharge it through the fan guard.For Versacool refer to separate instruction forms VC03,VC04 or VC05 if thermostatic controls are to be fitted.
AC Electric Motor Connections. Remove motor junctionbox and carefully check instructions on wiring which maybe displayed inside or outside of junction box. Electricmotors of various brands are used , some motors havestar connections and others may be wired delta. After wiringhas been completed start the motor and check for rotationof the fan. Rotation is usually c/w when viewed from themotor or ac/w when viewed from element. The fan shouldpull the cooling air through the cooling element anddischarge it through the fan guard. All AC electrical wiringshould be carried out by a licenced electrician.
Hydraulic Motor Driven Fans. Some units are suppliedfitted with Hydraulic fan motors. Hydraulic Motors fitted asfan drives must be piped to permit the fan to rotate freelyafter the oil flow has been shut off to the motor. Failure toprovide such a device may cause the fan to be damageddue to shock loads caused by fan inertia.

Maximum pressure cooler will be subject to: ___________ Bar.Advise if there are any cylinders or other pressure spike producing components in the cooler circuit.
If unsure of the values required the following information will help. Each number below corresponds to the number above1. Heat load: the heat load may be determined by:
A. Hydraulic oil cooling: Assume 30% of the input power will be rejected to heat. If the input power is unknown, thisformula may be used: kW= (system press. Bar) x (L/min flow) x 0.00167B. Hydrostatic oil cooling: Assume 25% of the input power will be rejected to heat.C. Heat load test: the heat load can be determined by actually measuring the degree temperature rise from a coldstart-up. This temperature rise is the exact amount of heat going into the oil. To run a heat load test, disconnect anyheat exchanger in the test loop. Record the increase in oil temperature every 5 minutes. Review the data received,and determine the greatest temperature rise in any 5 minute period.Heat load = system volume x oil heat capacity x (∆T oil temperature rise)
5 minutes x 60 sec./min
For example - Initial oil temp ................. 40°CFinal oil temp .................. 50°C Heat Load = 240 x 1.72 x (50-40) = 13.8 kWTime for temp rise .......... 5 minutes 5 x 60System oil volume .......... 240 litresOil heat capacity ............. 1.72 kJ/L°C
2. Oil flow rate: This is simply the flow rate of the oil circulating through the cooler.3. Oil type: Advise oil grade or viscosity vs temperature details4. Oil temperature: Oil coolers are typically sized using the maximum desired oil temperatures. Typical temp. ranges are:
Hydraulic oil ................... 43 - 54°C Hydrostatic drive oil ........54 - 82°CBearing lube oil .............. 49 - 71°C Lube oil circuits ...............43 - 54°C
5 Oil pressure drop: Most systems can tolerate a pressure drop through the heat exchanger of 1.5 to 2 Bar. Excessivepressure drop should be avoided. Care should be taken to limit pressure drop to 0.3-0.5 Bar for case drain applicationswhere high back pressure will blow out pump shaft seals.6. Cooling air temperature: This is the temperature of the air entering the cooler, also referred to as the ambient airtemperature. A normal maximum air temperature is usually between 32°C to 38°C. Care should be taken not to install inconfined space as ambient temperature will increase and cause overheating.7. Motor data: Most models are available with a wide variety of motors. List as desired. Be sure to indicate any specialrequirements.8. Envelope size: This may be any height, width and depth depending on the application. Allowances should be givenso as not to obstruct fan air flow.9. Air face velocity/cooling air flow: Typically oil coolers are sized for 5.5m/s (20 kph) air velocity. When an air volume
flow is given in m3/s, it may be converted by: AFV m/s = m3/s
face area of core in m2
