FAQs

The standard Hitachi horizontal screw compressor includes a built-in oil separator, solenoid valves with 120 volt coils for capacity control, oil strainer, suction gas strainer, oil sight glass, oil service valve, POE oil with corrosion-proof gas charge and sealed flanges. The sealed suction and discharge flanges are socket style flanges suited for "OD" sizes of refrigeration copper.

The compressor is equipped with external electrical connections for the three Positive Temperature Coefficient (PTC) sensors, which are internally installed in the hermetic motor windings. The electronic motor protection module, which responds to the PTC sensors, is available from ACCS (ACCS part number MOD1Z01A)

The evaporating temperature show indicates the saturated temperature of suction gas pressure to the compressor.

The cooling capacity for 60Hz and the motor input are based on the following:

Condensing Temperature, 104°F

Leaving Liquid Temperature, 95°F

Suction Gas Condition, Superheat 9°F

Refrigerant, R22
