MICROPROCESSOR CONTROLLER: This controller monitors analog and digital inputs to achieve precise control &
safety functions of the unit.( optional )
COMPRESSOR MOTOR INTERNAL OVERLOAD: The internal overload protects the compressor and senses the mo-
tor winding temperature in case of overload.
STARTERS: The starter is operated by the control circuit and provides power to the compressor motors. These devices
are rated to handle safely both RLA and LRA of motors.
UNDER VOLTAGE AND PHASE PROTECTION: Protects against low incoming voltage as well as single phasing, phase rever-
sal and phase imbalance by de-energizing the control circuit. It is an automatic reset device, but it can be set up for manual reset.
CRANKCASE HEATERS: Each compressor has crankcase heater. The compressor crankcase heater is always on
when the compressors are de-energized. This protect the system against refrigerant migration, oil dilution and potential
compressor failure.
SAFETY VALVE: This valve protects the unit against high discharge pressure in the system due to malfunction of high
pressure switches.
HIGH PRESSURE SWITCH: This switch provides an additional safety protection in the case of excessive discharge pressure.
UNIT ON-OFF SWITCH: ON-OFF switch is provided for manually switching the unit control circuit.
INDICATOR LIGHTS: lights indicates power ON to the units .
THERMOSTATIC EXPANSION VALVE: Thermostatic expansion valve is used to regulate the refrigerant flow to the
water cooler and maintain a constant superheat.
FILTER DRIER (REPLACEABLE CORE TYPE): Refrigerant circuits are kept free of harmful moisture, sludge, acids and
oil contaminating particles by the filter drier.
CONTROL CIRCUIT TRANSFORMER ( optional) : A factory mounted and wired control circuit transformer is furnished
eliminating the need for running a separate 115 volt power supply to the unit control circuit.
SIGHT GLASS: A moisture indicating sight glass installed in the liquid line. An easy-to-read color indicator shows mois-
ture contents and provides a mean for checking the system refrigerant charge.
LIQUID LINE SOLENOID VALVE: Closes when the compressor is off to prevent any liquid refrigerant from accumulating
in the water cooler during the off cycle.
DISCHARGE LINE MUFFLER ( optional ) : Discharge line mufflers are installed to eliminate noise due to refrigerant
pulsation.
VIBRATION ELIMINATOR: To eliminate the vibration transmitted from the compressor to the pipings and unit structure.
HOT GAS BYPASS SYSTEM (optional ) : Hot gas bypass is provided on the lead circuit to permit operation of the system
down to 50% of its unloaded capacity. Under low ambient condition, it controls temperature by eliminating the need to cycle
the compressoron and off, ensuring narrow temperature swing and lengthen the life span of the compressor .
WATER FLOW SWITCH (optional ): Paddle type field adjustable flow switch for water cooler circuits. Interlock into
unit safety circuits so that the unit will remain off until water flow is determine.
UNIT MOUNT SPRING ISOLATORS (optional): Designed for deflection. This housed spring assemblies have a
neoprene friction pad on the bottom to prevent vibration transmission.

The followingdesign requirementsmust be known to select a package chiller.
1. Required cooling capacity in tons
2. Leaving chilled water temperature in 0F (LCWT)
3. Chilled water flow rate in PM
4. Chilled water cooling range in 0F (water in temp. _water out temp.)
5. Design ambient temperature
6. Minimum ambient temperature
7. Altitude
8. Electrical power supply
SAMPLE SELECTION
Select an Air Cooled Packaged chiller for the following conditions:
Required system capacity is 90 tons at 540F entering chilled water
and 440F leaving water. Design ambient temperature is 950F.
Altitude is 2000 feet above sea level.
Water cooler fouling factor is 0.00010. Power supply: 380V-3Ph-60Hz.
STEP-1: UNIT SELECTION
Entering the capacity performance data at given LCWT and ambient temperature.
OALC100 chiller unit at sea level will produce100.3 tons and 113.5kW compressor
power input at 440F leaving chilled water temperature with 100F water temperature
difference and 950F ambient temperature.
For the conditions required, the unit actual cooling capacity when corrected for
altitude (0.99) and fouling factor (1.0).
Capacity = 100.3x0.99x1.0 = 99.2 Tons, which then exceeds the requirements.
So the selection is correct.

Referring to pressure drop chart, pressure drop at 216 PM = 11.5 ft. of water for selected model.
STEP-3: ELECTRICAL
Refer to electrical data at 380V-3Ph-60Hz, the main power wire size for OALC100 is to be sized for a minimum
circuit ampacity (MCA) of 325.4 Amps and maximum over current protection (MOCP) of 450 Amps.
STEP-4: CHILLED WATER PUMP SELECTION
For chilled water pump selection, add all pressure drop in the closed chilled water loop piping to the pressure drop
calculated in step 2.
STEP-5: LCWT CORRECTION
When a corrected LCWT is used, cooler pressure drop must also be corrected for new LCWT.
Refer to table-3. Add correction factor to design leaving chilled water temperature (LCWT) when chilled water tempera-
ture range is above 100F and subtract correction from design leaving chilled water temperature (LCWT) when water
temperature range is below 100F.
EXAMPLE:
If LCWT rise is 12.50F, enter correction curve at 12.50F and read the correction factor of 0.2. The corrected LCWT is
44+0.2 = 44.20F.
NOTE: 1. When the chilled water temperature rise is less than 50F, the high water flow rate will result to excessive
pressure drop. In such cases, contact factory for special selection of a cooler with wider baffle spacing.
2.Please refer to water pressure drop curves.

ETHYLENE GLYCOL SOLUTION CAPACITY CORRECTION (Antifreeze)
13
When operating in areas with temperatures below 320F(0
0C), cooler protection in the form of Ethylene glycol solution
(brine solution) is required to protect cooler from low ambient freeze-up. This brine solution must be added to water loop
to bring down the freezing point with a difference of 150F(8
0C) below minimum operating ambient temperature.
Ethylene glycol solution causes a variation in unit performance. To obtain the effective performance, it is necessary to
multiply the water performance data by correction factors corresponding to the ambient temperature or Ethylene glycol
percentage indicated in the following table.
EXAMPLE: English system- Determine Ethylene glycol percentage by weight and correction factors at 380F ambient
temperature.
From the above table, Ethylene glycol water solution concentration (percentage by weight) corresponding to 380F ambi-
ent temperature is 12% by weight.
Find the correction factors corresponding to 380F ambient temperature from the table.
Cooling capacity correction factor is 0.985, Flow correction factor is 1.02, Pressure drop correction factor is 1.07.
Apply these correction factors for corrected system performance values.
TONS (E.G. SOLUTION) = Tons (water) x Cooling capacity correction factor.
BRINE (E.G. SOLUTION) FLOW (GPM) = Flow (water) x Flow correction factor.
BRINE (E.G. SOLUTION) PRESSURE DROP = Water pressure drop (Ft.) x Pressure drop correction factor.
EXAMPLE: Metric system- Determine Ethylene glycol percentage by weight and correction factors where 3.30C ambi-
ent temperature.
From the above table, Ethylene glycol water solution concentration (percentage by weight) corresponding to 3.30C
ambient temperature is 12% by weight.
Find the correction factors corresponding to 3.30C ambient temperature from the table.
Cooling capacity correction factor is 0.985, Flow correction factor is 1.02, Pressure drop correction factor is 1.07.
Apply these correction factors for corrected system performance values.
KW (E.G. SOLUTION) = KW (water) x Cooling capacity correction factor.
BRINE (E.G. SOLUTION) FLOW (L/S) = KW (water) x Flow correction factor.
BRINE (E.G. SOLUTION) PRESSURE DROP = Water pressure drop (kPa) x Pressure drop correction factor.
Note: Correction factors apply to published chilled water performance rating from 400Fto50
0F (4.40Cto10 0C) LCWT.

NOTES
1. Main power must be supplied from a single field supplied and mounted fused disconnects, using dual element time delay fuse or circuit breaker.
2. The maximum incoming wire size is 500 mcm. On units having MCA greater than 500 mcm wire, the factory supplied power terminal block will
accept two parallel field wires per phase.
3. The compressor crankcase heaters must be energized for 12 hours before the unit is initially started or after a prolonged power disconnection.
4. Minimum and maximum unit supply voltages are shown in the tabulated data above.
5. Neutralline required on 380V-3Ph-60Hz & 380/415V-3Ph-50 Hz power supply only.

NOTES
1. Main power must be supplied from a single field supplied and mounted fused disconnects, using dual element time delay fuse or circuit breaker.
2. The maximum incoming wire size is 500 mcm. On units having MCA greater than 500 mcm wire, the factory supplied power terminal block will
accept two parallel field wires per phase.
3. The compressor crankcase heaters must be energized for 12 hours before the unit is initially started or after a prolonged power disconnection.
4. Minimum and maximum unit supply voltages are shown in the tabulated data above.
5. Neutral line required on 380V-3Ph-60Hz & 380/415V-3Ph-50 Hz power supply only.
