  • Type: Hermetic Scroll Compressor.
  • Refrigerant: Typically designed for R22, R407C, or R410A (check the nameplate specifically, as mixing refrigerants causes failure).
  • Displacement: Approximately 50 m³/h (varies by specific sub-model).
  • Motor Power: Typically ranges from 3HP to 5HP depending on the application voltage.
  • Cooling: Usually suction gas cooled.
  • Rotation: Scroll compressors are directional. They typically have a rotation sensor to prevent reverse rotation, which destroys the scroll set in seconds.
