For individual room temperature control in chilled water applications, Hi - Static fan coils can be an ideal solution on major projects involving:

• Apartment Complexes

• Offi ce Blocks

• Hospitals & Clinics

• Shopping Malls & Centers

• Airports

• Hi-rise Buildings

• Hotels & Motels

• Commercial Developments

• Schools & Colleges

• Libraries

Hi - Static fan coil units provide fl exibility of architectural design, economy of operation and space usage, individual room control with privacy, quietness, versatility of location and installation, and multiplicity of control system. All these reasons make the Hi - Static series fan coils the fi rst choice as Hi - Static Fan Coil units from SKM are: Built in the Gulf...for the world.

Features:

• High effi ciency coil with high effi ciency wavy corrugated fi ns.

• Hi-effi ciency, low power consumption PSC electric motor.

• Hi-effi ciency forward curved fan for quiet operation.

• Manual air vent.

• Heavy gauge galvanised casing & fan housing. Hot dip is standard.

• Quick electrical connections.

Component Features

Coils

Cooling & heating coils are manufactured from 3/8” (9.5mm) OD seamless copper tubes mechanically bonded to high effi ciency wavy corrugated aluminium fi ns. Copper fi ns are available as an option.

Coils are factory leak tested by air pressure at 300 psig (2068 kPa) under water. Air vent is standard. Chilled water cooling coils are available in 3, 4 and 6 rows. Heating coils are available in 1, 2, 3, 4 & 6 rows. DX coils are available in 3, 4 & 6 rows. Coil connections are plain tube extensions supplied LH or RH as required for chilled water and DX units.

Distributor for DX type Hi - Static fan coils is provided as standard with correct sizes and quantity of outlet pipes. Coils are rated in accordance with ARI - 410. Hi - Static fan coil units can be supplied with a maximum total of 6 rows/coil as follows :

• Cooling and heating with 4 and 2 pipe system combination up to a total of 6 rows only.

• Maximum 6 row cooling coil and electric heater battery.

• Maximum 6 row DX cooling coil and electric heater battery.

Fan / Motor

Hi - Static fan coil units use centrifugal double inlet double width low noise fans direct driven by single phase, 3-speed permanent split capacitor motor. These motors have integral thermal protection, low temperature rise, are highly effi cient, have high power factor and operate almost noiselessly with permanent lubricated sleeve bearings.

Motor Technical DataAll motors used in High Static Fan Coil Units are inherently protected by means of thermal cut-out embedded in the winding. This thermal cut-out is calibrated to trip out when the winding reaches a pre determined temperature. The thermal cut out will automatically reset when the temperature returns to a safe limit.

Effi ciency and Power FactorSKM High Static Fan Coil Units are equipped with permanent split capacitor motors because of their high effi ciency and higher power factor than that of shaded pole motors being used by many other manufacturers of fan coil units.

The effi ciency range of permanent split capacitor motors varies between 50 & 60 % as compared to 30 to 40 % for shaded pole motors with power factor 0.6 to 0.7 while the power factor of a permanent split capacitor motor approaches 1.0.

SKM chooses permanent split capacitor motor on the basis of their higher effi ciency and power factor in order to maintain the total power factor of the installation above a set minimum value.

Control System Description

Control System Operation

CP-1:

Two pipe system with valve cycled cooling only.

Thermostat cycles an electric 2-way or 3-way motorized valve. The fan runs as per the setting of Fan mode (On-Auto) and Fan speed (Hi-Med-Low).

CP-2:

Two pipe system with total electric heat

The thermostat opens an electric 2-way or 3-way motorized valve on cooling coil or closes the electric heating circuit for heating depending on which is required to satisfy the thermostat setting. The thermostat with manual selector switch for Heat-Off-Cool, Fan On-Auto and Hi-Med-Low speed allows to set the switches at the desired positions.

When ordering Code CP-2 and the electric heater option FEH, the auto high temperature cut out is provided as standard.

CP-3:

Four pipe system with valve cycled

The thermostat cycles 2 or 3-way motorized hot or chilled water valves to maintain desired room temperature. The thermostat with selector switch for Heat-Off-Cool prevents recycling.

Fan runs according to the setting of manual selector switch for speed (Hi-Med-Lo) and On-Auto mode.

Selection

Selection Considerations

In selecting Hi - Static Fan Coil units for a specifi c application the factors to be considered should include:

• Available space for the unit including fl oor to ceiling height.

• Presence of high sensible or peripheral loads in space.

• Functionality of intended space usage.

• Availability of access for pipes, drains & power.

• Compatibility with intended space fi nish.

• Fresh air and ventilation requirements.

• Noise level desired at peak or part load operations.

• Control system desired especially if winter heating is required.

• Economy of layout.

Once a particular model or models in the Hi - Static series is selected after consideration of the above factors, it is necessary to select the unit and coil size to match. It is possible to obtain different unit size with or without different coil depths to meet given design parameters.

The correct unit with correct coil size is obtained only when required cfm at defi ned speed; i.e. High, Medium or Low to meet sensible load of the space is matched to the correct coil providing the required sensible cooling or outlet temperature at given fl ow rate and design temperature rise with the unit operating at functional sound levels.To achieve this the engineer or designer must not only check aesthetic needs but also space limitations, psychrometric feasibility, circulation and ventilation, room acoustical effect, control system, piping accesses including overall chilled water circuits and effect of diversity on same.

Selection Procedure

It is recommend to use SKM selection software. If it is not suitable, then follow the procedure below :

1. Select unit that delivers approximately airfl ow required at desired speed and external static pressure from airfl ow rate tables. Select unit with airfl ow equal or more than that required.

2. Apply correction factors to selected unit and fi nd out the actual total and sensible cooling capacity.

3. Repeat step 1 if required parameter is not met with actual values obtained from initially selected unit.

Control PackagesSKM provides a variety of control options, a few of which are mentioned below. Please consult SKM sales department for other control applications. Aquastat for Heat-Cool auto changeover must be fi eld supplied and fi eld installed by others, if necessary.

Control System

The control systems for SKM Hi - Static FCUs can be selected provided the application is identifi ed for :

Cooling/Heating.

Cooling or Heating.

The control system can be:

- 2-pipe with valve cycled (Code CPI)

- 2-pipe with total electric heat (Code CP2)

- 4-pipe with valve cycled (Code CP3)Control valves in the control system are available in 2-way and 3-way motorized versions with compression ends for easy fi eld installation and replacement.

The location of the Thermostat and/or fan speed regulating switch determines the need for a remote or unit mounted control.

For remote mounting the options available are:

Combination wall mounting Digital Cooling thermostat with 3-speed switch (Code RTH1).

Combination wall mounting Digital Cooling/Heating thermostat with 3-speed switch and Heat-Off-Cool & Fan-On-Auto manual changeover switch (Code RTH2).

* Thermostats with deadband between cooling/heating can be supplied on demand.

For unit mounting the options available are:

1. Only 3-speed Fan switch (Off-Hi-Med-Lo) plus an additional aux. circuit for energizing electric valve (Code UFS1).

2. Cooling thermostat with external sensor (Code UTH1)

3. Cooling/Heating thermostat with external sensor and Heat-Off-Cool manual change-over switch and 3-speed switch (Code UTH2).
