• HFCs and HFOs refrigerants
• Hydrocarbons and Ammonia refrigerants
• R744: Transcritical & Subcritical CO2 models
• Two-stage models available
• All models VFD compatible
• Optional RSH capacity control
• Most models ASERCOM certified
• 2 year warranty standard


For standard refrigerants
Wide range of models with 2, 4, 6 or 8 cylinders, displacement from 4 to 239 m3/h [50Hz] and nominal power from 0.5 to 80 Hp.
The compressors can be used with all standard refrigerants like HFC, HCFC based refrigerants and HFO low-GWP refrigerants, for a wide range of applications, single and multi-compressor and cascade systems. All models can operate with VFD.
The main features are high efficiency, robust construction, low noise levels and small dimensions. The applied protection systems are state of the art. Finally, a long list of accessories further enhances their versatility.
The range includes also: ATEX Compressors, Two-stage compressors, Twin compressors and Open type compressors.
The performance of the majority of models is ASERCOM certified.

RSH - Patented Capacity Control

Frascold's patented Reduced SuctionHead technology allows our reciprocating compressors to run unloaded indefinitely. Unlike standard capacity control, RSH capacity lets the compressor run without overheating while energized. This revolutionary feature provides application flexibility while reducing heat, vibration and damage from unloading stress.

  • 2,4,6 and 8 Cylinders
  • Reduced wear and vibration
  • Run unloaded indefinitely
  • Efficient & reliable unloading
  • Frascold exclusive solution
  • Retrofit existing compressors
  • Selection Software
    Selection Software

    Our advanced FSS.3 selection software helps you accurately choose the right compressor combination for your application. Refine your results with the Check Calculation feature to maximize system performance.
