Stationary

VERY HIGH EFFICIENCY

Stationary refrigeration and air condition compressors have to be designed robustly and at the same time, low cost. High efficiency gives customers running-cost benefits quickly. Piston or scroll type compressors, typically hermetic design, are designed at OBRIST Engineering for this application field.

Stationary Piston Compressor with 100kWe

Applications: Supermarket and Refrigeration Plants

  • Using Compactness of R744 Properties
  • Smart Heat Management for Highest Efficiencies
  • Improved Valve System for High Speed
  • Active Oil Seperation and Intelligent Oil Management
  • Electrically Piston Compressor with inline or "V" Geometry
