74R3477 Receiver Drier – Heavy-Duty Mobile A/C

Description

The BTRAC 74R3477 Receiver Drier helps keep mobile air conditioning systems running reliably. It actively removes moisture and contaminants from the refrigerant. As a result, it reduces corrosion, protects internal components, and supports stable cooling performance.

In addition, this receiver drier plays an important role whenever technicians open the A/C system. Because moisture quickly damages A/C components, replacing the drier during service helps prevent future failures. Therefore, the 74R3477 supports long-term system health after repairs or component changes.

Mobile A/C systems often operate under long duty cycles. Because of this, dependable moisture control remains critical. The 74R3477 provides that protection in heavy-duty truck and fleet HVAC systems without changing the original system layout.

Based on validated interchange usage, this receiver drier is commonly used in commercial truck and vocational applications. As a result, it serves as a reliable service replacement when restoring proper refrigerant protection.
