NTZ - Low Temperature Reciprocating Compressors 

The Maneurop® NTZ series of reciprocating compressors from Danfoss Commercial Compressors are designed for low evaporating temperature applications with refrigerants R-404A and R-507A. The NTZ series is optimized at −35 °C with an extended evaporating temperature range from −45 °C to -10 °C. NTZ compressors have a large internal free volume that protects against the risk of liquid hammering when liquid refrigerant enters the compressor.
