BT5-4646 Sanden SD7H15HD A/C Compressor

Description

The BT5-4646 Sanden SD7H15HD A/C Compressor is built for heavy-duty mobile HVAC systems.
It is commonly used in Freightliner and other truck A/C applications.

This compressor uses a Sanden SD7H15HD style design.
It also features an ear 8 long mount and horizontal Tube-O fittings.

As a result, it is a strong replacement option for compatible Freightliner, truck, bus, and mobile A/C systems.

Function and Performance

An A/C compressor moves refrigerant through the air conditioning system.
It helps remove heat from the cab and supports steady cooling performance.

This compressor uses a 7-cylinder design with 9.5 cu. in. displacement.
It is made for R134a refrigerant and uses PAG100 oil.

In addition, the 2-groove clutch is designed for two 1/2 inch belts.
Because compressor fitment depends on voltage, mount, pulley, head style, and port layout, compare your current unit before ordering.

Durability and Design

The BT5-4646 compressor is designed for demanding mobile HVAC use.
Heavy-duty truck systems often face heat, dust, vibration, and long run hours.

This unit uses an ear mount and a 132mm 2-groove clutch.
It also has horizontal Tube-O fittings with a 1″-14 fitting size.

The product data lists an MDA head type.
Additional dimensional data lists an MJA back head, so compare your current compressor before ordering.

Installation

Install this compressor according to the vehicle or equipment service procedure.
Then confirm belt alignment, refrigerant type, oil type, wiring, and fitting style.

Before installation, compare the current compressor to the specs below.
Also, replace the receiver drier or accumulator when the A/C system is opened.

For best results, flush the system if needed.
Then confirm that your original part number matches one of the listed interchanges.
