f. Water-Cooled Condenser Section (Optional)

The water-cooled condenser section consists of water-cooled condenser, sight glass, moisture-liquid indicator, quench expansion valve, rupture disc, condenser pressure transducer (CPT), filter-drier, suction modulation valve, suction solenoid valve,

discharge pressure regulator valve, water hook-up couplings and water pressure switch.

The supply temperature sensor (STS), supply recorder sensor (SRS) and ambient sensor (AMBS) are located at the right side of the compressor.
