Semi-hermetic refrigeration compressor ZF*K4E

scrollR404AR449a

Copeland™ ZF scroll compressors are developed to provide the best performance for low temperature applications. The line-up has a wide application envelope as it can operate from -40°C evaporating temperature to +7°C. The compressor design has been optimized to perfectly fit frozen food application requirements. Thanks to their scroll compliance mechanism, these scroll compressors feature particularly high tolerance to liquid slugging. Nominal Voltages230, 380, 400, 460 V Frequency50, 60 Hz ApplicationsLow Temperature Features -Wide operating envelope with 10°C low condensing temperature to minimize energy consumption -One model for multiple refrigerants -Light weight and compactness, up to half the weight of equivalent semi-hermetic compressor -Optional sound shell allowing up to 10 dBA sound attenuation -ZF models with liquid injection - Easy, efficient and reliable injection via Discharge Temperature Control Valve (DTC) -ZF models with enhanced vapor injection: - Seasonal efficiencies compared to Emerson’s best semi-hermetic compressors - Improved system capacity and efficiency by 40% and 25% respectively, making them the most efficient compressors on the market -Possibility to reduce the equipment and component sizes by using smaller compressors
