The Maneurop® NTZ series from Danfoss Commercial Compressors is a range of hermetic reciprocating compressors for low evaporating temperature applications. These compressors replace the former LTZ range.
The NTZ series is engineered as a true low temperature compressor, optimised with R404A at -35°C with an extended evaporating temperature range from -45°C up to -10°C.
NTZ compressors have a large internal free volume that helps to reduce the risk of liquid hammering. The electrical motor is fully suction gas cooled. That means no additional body cooling is required and it allows the compressor to be insulated with an acoustic hood when the installation requirements call for extra low sound characteristics.
