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.

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 Copeland’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
