WATER-COOLED PACKAGE UNITS
GENERAL DESCRIPTION
¯
The compact, rugged and reliable WCP/ WCPSCH, water-cooled, horizontal single packaged
unit, is designed to meet the owners, consultants
and contractors requirement of efficient, quiet and
dependable performance. The wide range of
cooling capacity satisfy most requirement for
offices, industrial buildings, supermarkets, shops
etc. These units are factory assembled, leak
tested, evacuated, dehydrated, precharged with
correct amount of refrigerant, tested run in factory
and ready for installation.
Leak and pressure tested to 450 psig.
Fully Leak
Circuit
Tested
Refrigerant
¯ Leak and pressure tested at 450 psig.
¯ Pressure ports are provided on the discharge,
liquid and suction line.
¯ Evacuated, dehydrated and charged with
refrigerant.
Safety Components
High pressure and low pressure cut outs for
model WCP 35CH and above, to guard against
compressor damage due to high discharged head
pressure and system leakage respectively.
Reciprocating Compressor
(WCP-CH Series)
Hermetic reciprocating, refrigerant gas cooled
high torque induction motor, quiet running with
internal suspension system to eliminate vibration
and internal inherent line break motor protection.
Crankcase heater to prevent liquid migration
during off cycle and eases start-up (for 3 phase
unit only).
Efficient Evaporator Coil
¯ Model 68 and above independent thermal
expansion valve with external equalizer for
better refrigerant control and wider load
condition.
¯ Leak and pressure tested to 450 psig
Scroll Compressor(s)
¯ Evacuated,
refrigerant.
(WCPS-CH Series)
Reliability
¯ No contact scroll
design that minimizes
friction, increases
volumetric efficiency
and reduces vibration,
thus longer service life.
¯ Suction gas cooled
motor.
dehydrated
and
charged
with
Drive Package and Blowers
(WCPS 68CH - 285CH)
¯ Belt driven drive package offers flexibility on
various air flow rate and various static
pressure applications.
¯ Single large diameter double inlet double width
blowers reduce the noise level and eliminates
the need for common transition and eliminates
air unbalance.
Low Power
Consumption:
¯ High EER.
¯ No crankcase heater
required.
Casing
¯ Constructed of electro galvanized steel sheet
and insulated with 1/2” thick x 1 1/2 lb per cu.ft
linacoustic fiberglass.
¯ Aesthetically coated with powder paint to
provide excellent finish, weatherability and
corrosion resistance.
¯ Removable panels on the left and right hand
side of the unit to provide access to critical
parts and components.
Cleanable Shell and
Tube Condenser
¯ Multiple 3/4” O.D. copper
finned tubes with 25 to
30% more surface area
ensure
better
heat
transfer.
¯ Integral subcooling circuit
to maximize efficiency.
¯ Provided with fusible plug
for safety purpose.
Filters
Side loading 1” thick filters - from both sides-thus
eliminates unnecessary duct opening at site.

WATER-COOLED PACKAGE UNITS
Optional Accessories Features
¯ Hydrophilic aluminum fins, copper fins or
tinned coated copper fins for better corrosion
resistance.
¯ Factory wired starters
- DOL for compressors and fan motors.
- Auto-transformer for compressors.
¯ Hot gas by pass for low load conditions.
¯ Decorative discharge plenum.
¯ Hot water heating coils.
¯ Suction stop valve(s), discharge stop valve(s)
and liquid stop valve(s).
¯ External spring vibration isolators for blower
fan and drive assembly.
¯ Thermostat.
¯ Electric heaters.
¯ R407C refrigerant instead of R22.

5.) Power supply for blower is 400V-3-50Hz except for WCP
18CH to WCP 56CH which is 230V-1ph-50Hz.
6.) Minimum-maximum voltage is 230V± 6%, 400V ± 6%.
7.) For other power supply requirements, please contact the
Dunham-Bush sales office.
NRA = Nominal Running Ampere.
LRA = Locked Rotor Ampere.
FLA = Full Load Ampere.
MRA = Maximum Running Ampere.

If the capacity after multiplying the sensible with the
correction factor exceed the total capacity, then the
sensible must be equal to the total.
