FR Series - 4NFRY
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.
- The slimmest compressor in its class with a width of just 305 mm or 367 mm
- Wide speed range from 500 to 2,600 rpm
- Disproportionately low increase in cooling capacity at high speeds
