Selection Notice
Cooling capacity cannot be determined from motor horsepower or displacement alone. It varies according to the refrigerant, evaporating temperature, condensing temperature, superheat, subcooling and electrical configuration.
Please provide the required refrigerant, operating temperatures, power supply and complete application conditions before ordering. Refrigerant compatibility, operating envelope and maximum permitted frequency must be verified using Frascold Selection Software.
