BT5-4537 24V Heavy-Duty A/C Compressor – SD5H14, Ear Mount, 2-Groove 132mm, K Head

Description

Overview

The BT5-4537 SD5H14 compressor is engineered for 24-volt heavy-duty mobile air conditioning systems that require a robust ear-mount design and reliable belt alignment. Because of its ear 8-long mounting style, the compressor provides improved stability in applications exposed to vibration and extended operating cycles. At the same time, the 2-groove, 132 mm clutch supports consistent belt engagement across traditional dual-belt drive systems.

Additionally, this unit uses a K-style head with rear-clocked horizontal O-ring ports, which allows for flexible hose routing in both OEM and aftermarket installations. As a result, it integrates easily into replacement and retrofit systems. Furthermore, its simple 1-wire bullet electrical interface ensures compatibility with standard 24-volt heavy-duty A/C control circuits.
