Screw compressors for HFC/HFO

BITZER screw compressors for HFC and HFO refrigerants support a wide range of applications using low-GWP refrigerants, combining flexibility, efficiency and future-proof system design.

Finely tuned capacity control via mechanical capacity sliders or through speed control with a frequency inverter ensures high efficiency even at part load. With electronic components and economiser operation, systems can be further optimised. Important application ranges include:

• Liquid chillers
• Air conditioning
• Process cooling and process heating
• Heat pumps, for example for district heating
• Marine operation

Displacement:

• Semi-hermetic screw compressors: 84 to 1015 m³/h at 50 Hz
• Compact screw compressors: 137 to 2000 m³/h at 50 Hz
• Compact screw compressors with integrated frequency inverter: 464 to 1206 m³/h at maximum speed
• Open drive screw compressors: 84 to 535 m³/h at 2900/min
