Bitzer - Reciprocating Compressor | FR Series

A special version was developed for transport refrigeration systems on the basis of the proven 4UFC(Y) .. 4NFC(Y) compressors designed for vehicle air conditioning. This new series – 4UFR(Y) .. 4NFR(Y) – can be used with R404A, R507A and R22 (“R” = refrigeration) in a wide range of applications – medium to low temperature applications. With outstanding technical features made popular by the air conditioning models, these compressors offer high efficiency and reliability in BITZER quality.

Technical Features

• The slimmest compressor in its class with a width of just 305 mm or 367 mm
• Drive via V-belt with electro- magnetic clutch – other drive types are also available, application upon request
• Wide speed range from 500 to 2,600 rpm
• Disproportionately low increase in cooling capacity at high speeds

Optimised Drive Gear

• Highly smooth running thanks to the 4- and 6-cylinder design and dynamical mass compensation
• Low frictional losses thanks to the surface-hardened drive shaft and optimised pistons, as well as the hard-chrome-plated piston rings
• Strengthened connecting rod geometry with large bearing surfaces
