SPECIAL ORDER ITEMS
In some applications, units can be manufactured with optional components for added
performance and longevity. Below are a few of the PWC options that are available.
Consult your distributor for pricing and availability.
CUPRO-NICKEL CONDENSER
When chemically treated water, salt water or brine, is used in the condenser coil, it is
recommended that the PWC be equipped with a 90/10 Cupro-Nickel condenser coil.
HIGH PRESSURE WATER VALVE
For applications where water supply pressures exceed 150 psig, a high pressure water
regulating valve can be installed in the PWC. Valves designed for use with up to 350 psig
water inlet pressure are available.
HERESITE TREATED EVAPORATOR COIL
For use in chemically corrosive environments, the PWC can be manufactured with a
Heresite® dipped evaporator coil for improved coil life.
HOT GAS BYPASS VALVE
In applications where low evaporator temperatures may occur, an optional hot gas bypass
valve can be installed to regulate the evaporator temperature. The bypass valve feeds
refrigerant (hot gas) into the evaporator to avoid low ambient freeze-ups.
MARITIME WATER VALVE
Cast naval bronze body with MONEL parts. MONEL is a “natural alloy” and is highly re-
sistant to corrosion.
TOWER UNITS
In applications where the PWC is connected to a closed-loop condenser water circuit, a
unit can be built for direct water connection WITHOUT a water valve.
