BT4-0129 Receiver Drier – Heavy-Duty Mobile A/C (Kalori)

Description

The BTRAC BT4-0129 Receiver Drier helps maintain reliable air conditioning performance by removing moisture and debris from the refrigerant circuit. Because it reduces internal corrosion and stabilizes system operation, this receiver drier can extend compressor life and improve overall cooling reliability.

This receiver drier matches the Kalori HVAC component family and uses a horizontal body design commonly specified in mobile air conditioning systems. The compact layout allows easier installation in confined engine-bay or rooftop HVAC locations while maintaining effective moisture control.

In addition, the Kalori-style configuration supports standard O-ring connections, which integrate cleanly with common mobile A/C hose and tube layouts. As a result, technicians can service or replace the receiver drier without modifying the system.

Because it works with R-134a refrigerant, the BT4-0129 installs smoothly into existing heavy-duty HVAC architectures. Therefore, it supports dependable performance across fleet, vocational, and specialty vehicle applications.
