Copeland CR series compressors are designed for high efficiency and reliability in refrigeration, air conditioning and heat pump refrigeration. These compressors offer a wide range of operating conditions and excellent reliability, and are equipped with an in-built motor protector and an in-built pressure relief valve to further enhance overall stability.
Case Details
Emerson has developed the next generation CR Series Compressors which utilize R407C refrigerant. These new CRK6ME and CRKQME reciprocating models provide customers with the opportunity to switch from R22 refrigerant to R407C refrigerant. These compressors are available with POE oil which allows oil and refrigerant to mix well, and provides ideal oil return back to the compressor. These compressors deliver superior performance, have a wide operating range, offer multiple
electrical options and come with a host of other features.
Copeland CR series compressors have the following distinctive features:
High efficiency and low noise: by modifying the internal silencer, it is possible to reduce the compressor exhaust pulse by 67 per cent; improved mounting of rubber gaskets to reduce vibration transmission.
Compact design: space-saving installation and easy maintenance.
High reliability: built-in motor protector and pressure relief valve ensure the compressor is protected in case of abnormal conditions.
Suitable for medium and high temperature refrigeration applications: stable operation in different temperature conditions.
Copeland CR series compressors are widely used in the following scenarios:
Central air-conditioning: To provide cooling for large buildings.
Industrial chiller: For cooling in industrial production process.
Cold storage: For low temperature storage of food, medicine and other items.
Naming rules of Copeland CR series compressors:
Example1CR47KQ-TFD-522Refrigerant: R22
Voltage: 380-420V ~ 50 Hz 3 phase, 460 ~ 60 Hz
Oli Polyester: 1.70 Litre
These compressors typically have an energy efficiency ratio of around 12 per cent higher than piston compressors on the market.
