The BT5-4052 compressor is built on the Sanden SD7H15E platform, a high-capacity 7-cylinder design engineered for continuous-duty mobile HVAC systems in agricultural, construction, and off-road equipment. This unit operates on 24 volts, uses R134a refrigerant, and is factory filled with 300cc of PAG100 oil. The GV head configuration incorporates a rear universal O-ring FLX-7 pad with horizontal port orientation, supporting flexible hose routing and broad application compatibility. A 125mm 2-groove clutch, designed for two 1/2″ belts, provides reliable torque transfer in heavy-duty belt systems. The 1-wire male Packard connector with diode and bullet jumper ensures proper clutch engagement and electrical protection, while the long key shaft and direct-long mount provide OE-correct installation.
