Semi-Hermetic Compressors Line Up
Semi Hermetic Compressors Standard - R407C
The semi-hermetic reciprocating compressor range comprises small K and L compressors, ideal for applications such as condensing units or refrigerated transport systems, and D2S to D8S compressors from 2 to 8 cylinder for units or compact compressor packs for medium to large supermarkets and comfort applications. It is suction gas cooled and uses reed valve technology, found on all reciprocating compressors except Discus™. All compressors are designed for unquestionable reliability and uses positive displacement high flow oil pump that guarantees high oil feeding pressure for good lubrication and bearings’ cooling. Key features and benefits include:
  • Integrated oil pump and Electronic Oil Pressure Switch OPS1 for durability
  • Two motor sizes per displacement, optimized for different applications
  • Large operating envelope that allows medium and low temperature applications to be covered by one single model
  • Provide cooling capacity modulation either by cylinder head blocked suction or with use of frequency inverters from 25 to 60Hz with the standard AWM motors
  • Multi-refrigerant compressor range – one model to cover all standard refrigerants
