BT5-2521214 Heavy-Duty A/C Compressor – TM-31, 24V, PV8

The BT5-2521214 A/C compressor is built for heavy-duty mobile air-conditioning systems that require consistent cooling under continuous load. Because it uses the robust TM-31 compressor platform, it supports higher displacement and improved thermal control compared to smaller compressor families.

In addition, the direct-mount design simplifies installation while maintaining accurate alignment in OE brackets. As a result, installation time is reduced and long-term belt tracking improves.

Furthermore, the horizontal O-ring fitting layout allows clean hose routing and helps minimize leak points. Therefore, system reliability improves during extended duty cycles and high-ambient operation.

The BT5-2521214 operates on a 24-volt electrical system and uses a PV8 clutch with a 152 mm diameter. Because of this larger clutch design, torque transfer remains stable even under high compressor loads.
