Product catalog summary
Introduction
The document introduces a special design of compressors for truck and trailer refrigeration applications, based on the approved 4UFC(Y) .. 4NFC(Y) series for vehicle air-conditioning. The new series, 4UFR(Y) .. 4NFR(Y), is suitable for refrigerants R404A, R507A, and R22, and is applicable for medium to low temperature refrigeration.

Technical Specifications
The compressors are designed to operate at a motor speed of 1750 RPM (60 Hz) and are based on the latest ARI 540 standards. Performance data are provided without liquid subcooling, which results in lower cooling capacity and efficiency values compared to data with 15°F subcooling.

Performance Data
Performance data are presented for various compressor types (4UFRY, 4TFRY, 4PFRY, 4NFRY) with cooling capacities and efficiency ratings at different saturated suction and discharge temperatures. The data highlight the impact of zeotropic blends on pressure levels and liquid temperatures.

Application Limits
The document outlines the application limits for R404A and R507A refrigerants, specifying the speed range (500 – 2600 RPM) and the need for additional cooling or limited suction superheat.

Dimensional and Connection Details
Dimensional drawings and connection positions are provided, detailing the standard positions for shut-off valves and various connection points, including high and low-pressure connections, oil fill plug, and sight glass.

Conclusion
The document concludes with contact information for Bitzer Kühlmaschinenbau GmbH, the manufacturer of the compressors.
