Emerson Climate Technologies developed the ZF range to provide the best performance in low temperature. The range has a wide application envelope as it can operate from -40°C evaporating temperature to +7°C. They have been optimized in their design to perfectly fit frozen food application requirements. Thanks to their scroll compliance mechanism, these scroll compressors feature particularly high tolerance to liquid slugging.
The range consists of:
• The ZF*KCE models that operate with liquid injection in order to control discharge temperature and increase the operating envelope.
• The ZF*KVE models that are optimized for vapor injection with use of a sub-cooler. This boosts refrigeration system's cooling capacity and efficiency.
• The Summit ZF* K6E models that operate both with liquid injection or vapor injection.
Features and Benefits
• Wide operating envelope with 10°C low condensing temperature to minimize energy consumption
• One model for multi-refrigerants
• Light weight and compactness, more than half the weight of equivalent semi-hermetic compressor
• Optional Sound Shell allowing 10 dBA sound attenuation.
• ZF models with liquid injection - Easy, efficient and reliable injection via Discharge Temperature Control Valve (DTC) on the smaller models
• ZF models with Enhanced Vapor Injection
- Seasonal efficiencies compared to Emerson's best semihermetic 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
