ZF33K4E-TWC-551

SKU: 8509716

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
