Carlyle's 5F/H compressor is a workhorse when it comes to comfort cooling, industrial processes, low temperature food storage, and many other commercial and industrial applications.

These competitively priced compressors have over 50 years of proven reliability in the toughest application environments around, are completely field repairable, and are compatible with the modern refrigerants used today including R-22, R-134a, R-404A and R-507. The flexibility of the 5F and 5H permits a choice of motors, either belt or direct drive, to match refrigerant and job requirements.
 
 
 
  Automatic unloaded starting makes the use of expensive high torque motors unnecessary, saving on initial costs. As cooling load changes, the capacity control automatically adjusts compressor capacity to as low as 25% of full design load, reducing horsepower requirements and demand charges. This part-load operation increases energy efficiency and lowers utility bills.
 
 
 
  The design of the crankcase casting, cylinder heads and valve plates allows for a smooth, unrestricted refrigerant flow through the compressor, resulting in greater operating efficiency. Positive pressure lubrication is provided by a large capacity manually reversible oil pump, an automatic pressure regulator and an oil filtering system, resulting in extended compressor life.Efficient crankcase heater design prevents liquid refrigerant accumulation in the crankcase during shutdown. This assures undiluted oil supply throughout the compressor.
 
 
 
  A two-piece shaft seal assembly virtually eliminates seal leakage. A carbon ring, in combination with a neoprene bellows, seals tightly against a highly polished seat. The seal assembly is completely surrounded by an oil bath for maximum reliability over a wide temperature range.
