NATURAL REFRIGERANT SELF- CONTAINED PROPANE CHILLER

Natural Refrigerant Propane Chillers are highly efficient and climate friendly.

The Natural Refrigerant Propane Chillers contains a semi-hermetic screw compressor with features as:

  • Automatic capacity control via a Modulating Unloading Valve which decreases energy consumption
    Superior part-load performance
  • PID chilled water set-point through slide valve
  • Precise Rotor Tip Clearance reduces the leakage between high and low pressure cavities during compression
  • Step capacity control
  • Compressor motor protector
