Maneurop® MT and MTZ series compressors are of the hermetic reciprocating type and are designed for medium and high evaporating temperature applications. The MT series is designed for use with the “traditional” R22 refrigerant, using Danfoss Maneurop® mineral oil 160P as lubricant. The MT series can also be applied with several R22 based refrigerant blends (substitute refrigerants), using 160 ABM alkylbenzene as lubricant. The MTZ series is specifically designed for use with the HFC refrigerants R407C, R134a, R404A, and R507, using 160PZ polyester oil as lubricant. These compressors can be used in new installations and also to replace Maneurop® MTE compressors in existing installations. MT and MTZ compressors have a large internal free volume that protects against the risk of liquid hammering when liquid refrigerant enters the compressor. MT and MTZ compressors are fully suction-gas cooled.This means that no additional compressor cooling is required and allows the compressors to be insulated with acoustic jackets, to obtain lower sound levels, without the risk of compressor overheating. MT and MTZ compressors are available in 26 different models with displacement ranging from 30 to 543 cm3/rev. Seven different motor voltage ranges are available for single and three phase power supplies at 50 and 60 Hz. Most compressors exist in two versions:
- standard version
- VE version (oil equalisation + oil sight glass).
