Product description

•

Semi-hermetic two-cylinder reciprocating compressor with suction gas-cooled drive motor.

•

The refrigerant coming from the evaporator is entering the compressor and flowing over

the motor. This ensures an especially intensive cooling of the motor. Therefore the motor
temperature remains on a relatively low level - especially at high load.

• Oil pump independent of direction of rotation for reliable and safe oil supply.

•

One decompression valve each on the low and high pressure side, which vent into the

atmosphere when these inadmissibly high printing pressures are reached.
