Product catalog summary
Overview: This document details the innovative lightweight compressor series developed by BITZER, specifically models 4UFC(Y) to 4NFC(Y) and 6UFC(Y) to 6NFC(Y), designed for vehicle applications. These compressors are engineered for extended speed ranges and optimized for variable-speed vehicle engines.
Specifications: The compressors boast a compact design, low weight, high efficiency, and recognized reliability. They are primarily optimized for the refrigerant R134a, with options for other refrigerants upon request. The speed range is extensive, from 500 to 3500 RPM, and they are the slimmest in their class with widths of 305 mm or 367 mm.
Technical Features: Notable technical features include a patented shaft seal with a secondary oil barrier, smooth operation due to four and six-cylinder designs, low friction losses, and exchangeable, wear-resistant cylinder liners. They also feature a combined roller and sleeve bearing for the eccentric shaft, lubrication via a reversible oil pump, and an integrated pressure relief valve.
Optional Accessories: Available accessories include capacity control, an electro-magnetic clutch, and a crankcase heater. Additionally, optional oil dryers and dynamic working valves are offered for enhanced reliability and efficiency.
Application Limits: These compressors are optimized for vehicle engines operating at variable speeds, with a maximum speed limit of 3500 RPM. Under certain conditions, additional cooling or limited suction gas superheat may be necessary.
Performance Data: Performance data is provided for various compressor types at a suction gas temperature of 20°C, without liquid subcooling, and at a compressor speed of 1450 RPM. The document includes conversion factors and application limits for different operating conditions.
