PACKAGE CHILLER DESCRIPTION
CONDENSER
Air-cooled copper tube aluminum fin condenser coil.
Direct drive propeller type fans with DDP motors and
built-in overload protection. Design test pressure 150
PSIG low side, 300 high side.
EVAPORATOR
Brazed plate counterflow heat exchanger fed by
externally-equalized thermostatic expansion valve.
COMPRESSOR
Hermetically-sealed
reciprocating
Maneurop
compressor with oil level sight glass, rotalock service
valves, and crankcase heater.
CIRCULATION PUMP
Base mounted end suction centrifugal pump. Impeller
trimmed for 35% propylene glycol mixture.
RESERVOIR TANK
Constructed stainless steel. Insulated with ½” closed
cell foam insulation
SUPPLY & RETURN PIPING
Constructed of type M copper. Supply and return
stainless steel manifold with auxiliary ports. Quick
connect fittings provided for up to four connections.
Liquid-filled pressure gauge for setting discharge
pressure.
DYNAMIC FLUID BYPASS VALVE
Allows for balancing of discharge pressure. Over
pressure design allows circuiting back to tank without
damage to system or pump. Copper and bronze
construction.
REFRIGERANT PIPING
Type L ACR copper. Liquid line-filter drier, sight
glass/moisture indicator, solenoid valve and thermal
expansion valve with equalizer. Suction line fully
