Frascold FVR-H Medium-Temperature Semi-Hermetic Screw Compressors
PRODUCT DESCRIPTION
The Frascold FVR-H Series comprises semi-hermetic screw compressors designed for medium-temperature and higher evaporating-temperature refrigeration applications.
FVR-H compressors provide compact construction, low sound levels and efficient, reliable operation. They are suitable for variable-frequency drive operation and can be used as individual compressors or combined in parallel compressor systems.
The listed models cover nominal motor sizes from 40 HP to 180 HP and nominal displacements from 120 to 540 m³/h at 50 Hz. Compressor selection must be confirmed according to refrigerant, evaporating temperature, condensing temperature, required cooling capacity and electrical supply.
