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.

Screw compressors for refrigeration

For standard refrigerants Wide range of models with displacement from 115 to 538 m3/h (50 Hz) and nominal power from 30 to 180 Hp. All compressors can use all standard refrigerants like HFC, HCFC based refrigerants and HFO blends, and they are mainly used for LT or MT process applications but also for AC systems. Electronic protection system is built into every compressor or Diagnose technology as optional. Efficient, not noisy and reliable. The maximum efficiency is obtained with two different Vi (compression ratio) and it is possible to extend the operating field with oversized electric motors. Step capacity control, step, done by means of a slide valve, and use of economizers allowed with the optional connection kit. All compressors can run with external VFD. A large selection of accessories brings additional flexibility and all models. FVR and NR series Models: 38 Displacement: 120 - 538 m3/h Motor Power: 30 - 180 HP 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.
