Frascold FVR-L Low-Temperature Semi-Hermetic Screw Compressors
PRODUCT DESCRIPTION
The Frascold FVR-L Series comprises semi-hermetic screw compressors designed for low-temperature commercial and industrial refrigeration applications.
The series combines compact construction, low sound levels and reliable operation with high refrigeration efficiency. FVR-L compressors are suitable for variable-frequency operation and can be installed individually or in parallel compressor systems.
The listed models cover nominal motor sizes from 30 HP to 160 HP and nominal displacements from 120 to 540 m³/h at 50 Hz. Final compressor selection must be based on refrigerant, evaporating temperature, condensing temperature, required cooling capacity, power supply and operating conditions.
