Reciprocating compressors
Frascold designs and manufactured a modern and complete range of reciprocating compressors, semi-hermetic and open, to be used with all HFC, HCFC, HFO, CO2, HC, NH3 refrigerants in refrigeration and air conditioning systems.
The considerable experience collected during the years allows us to provide next generation products, in line with the latest market requests.
Additional equipment and devices are available to satisfy the peculiar requirements of applications all over the world, always focusing on energy saving and respect for the environment.
Moreover, all the directives concerning quality and manufacture issued by the relevant authorities are to be followed faithfully.
For HFC/HFO/HCFC 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 for a vast range of applications, in single, multi-compressor and cascade systems; the whole range can operate with an inverter. Appropriate for traditional HFC, HCFC based refrigerants and new HFO low-GWP refrigerants; Natural refrigerants.

This range is characterised by high efficiency and, the consequent saving in operating expenses. The project also guarantees sturdiness, low noise levels and small devices. The adopted protection systems are state of the art and a long list of accessories further enhances their versatility .

The range includes also ECOinside compressors streamlined for use with R134a and R1234ze refrigerants.
ATEX Compressors; with integrated inverter; For CO2 applications in subcritical and transcritical cycle; Two-stage models; Twin Builds.
The performance of the majority of models is ASERCOM-certified, while the whole range is UL certified. Other certifications are also available upon request.
