OPTIONS
In some applications, units can be manufactured with optional components for added
performance and longevity. Below are a few of the POLARIS options that are available
for units.
Consult your distributor for pricing and availability.
TOWER UNITS
In applications where the POLARIS is connected to a closed-loop condenser water cir-
cuit, a unit can be built for direct water connection without a water valve.
HIGH PRESSURE WATER VALVE
For applications where water supply pressures exceed 150 psig, a high pressure water
regulating valve can be installed in the POLARIS. Valves designed for use with up to 350
psig water inlet pressure, are available.
CUPRO-NICKEL CONDENSER
When chemically treated water, salt water or brine is used in the condenser coil, it is rec-
ommended that the POLARIS be equipped with a 90/10 Cupro-Nickel condenser coil.
ACRYLIC TREATED EVAPORATOR COIL
When airborne contaminants are a problem for air conditioning applications, acrylic
coated evaporator coils are recommended to guard against pitting or corroding.
HERESITE TREATED EVAPORATOR COIL
For use in chemically corrosive environments, the POLARIS can be manufactured with a
Heresite® coated evaporator coil for improved coil life.
HOT GAS BYPASS VALVE
In applications where low evaporator temperatures may occur, an optional hot gas by-
pass valve can be installed to regulate the evaporator temperature. The bypass valve
feeds refrigerant (hot gas) into the evaporator to avoid freeze-ups.
