2DB4-50-AWM/D-X0000

SKU: 4637586

From 2, 3 and 8 cylinder semi-hermetic reciprocating compressors for medium/low temperature refrigeration and high temperature applications like process cooling or air-conditioning. The key difference between Discus and traditional reciprocating technologies lies in the valve plate design. The Discus valve plate allows gas to flow into the cylinders with a minimum heat gain, while suction cavities are designed to smoothly route the gas to minimize losses.

Features

  • Highest level of efficiency available on the market, whatever the refrigerant and operating condition
  • Integrated oil pump and Electronic Oil Pressure Switch OPS2 for maximum reliability
  • 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 with condensing limit as low as 5°C
  • Provide cooling capacity modulation either by cylinder head blocked suction or with use of frequency inverters from 25 to 60Hz
  • Multi-refrigerant compressor range – one model to cover all standard refrigerants
  • Option to use 2 and 3 cylinder models with additional demand cooling function in order to achieve extended low temperature operating envelope without any superheat restriction for new refrigerants R407A/F, R448A and R449A.
