Zf copeland scroll compressor catalogue. These c An overview of the Copeland horizontal variable speed scroll compressors and variable frequency drives (VFDs), EVM/EVH series, capacities and refrigerants available. Copeland developed the ZFKQ range of croll compressors to provide the best performance in low temperatures. Compressor protection ZF*KQE and ZFI*KQE compressors are supplied with internal thermal protectors that prevent motor overheating in case of loss of phase or low refrigerant charge. Copeland scroll compressors set industry standards for high reliability and outstanding performance for water heating, making them the preferred choice for hotels, restaurants, and hospitals. As a result, system pressures and temperatures are tightly controlled. scroll technology provides continuous, stepless modulation from 10% to 100% with no operating envelope restriction. Copeland, a leader in compression technology solutions, developed the ZF range of refrigeration scroll compressors to provide the best performance in medium to low temperatures application. The series has a wide application envelope that can operate from -40°C to +7°C evaporating temperature. The ZF*KQE models that operate with liquid injection through DTC Valve in order to control the discharge temperature. .
