3-7HP Copeland Compressor Refrigearation Condensing Unit for Commercial Low Temperature Cold Room

3-7HP Copeland Compressor Refrigearation Condensing Unit for Commercial Low Temperature Cold Room. Adopts Copeland patented dual-flex scroll design with radial & axial flexibility for great resistance to liquid slugging and dirt accumulation. Fitted with Copeland ZF low-temperature scroll compressors tailored for low-temperature refrigeration. Liquid injection cooling controlled by DTC valves regulates discharge temperature and widens operational scope, adapting to low temperature and high ambient working conditions. Equipped with hydrophilic aluminum foil for fast condensate drainage, smooth airflow and better condenser anti-corrosion performance. Compressor jacket lined with sound insulation cotton to effectively cut down operation noise. Liquid-line solenoid valve stops liquid refrigerant backflow after shutdown and avoids compressor damage from liquid hammer.
