74R4239 Receiver Drier – Heavy-Duty Mobile A/C

Description

The Red Dot 74R4239 Receiver Drier protects mobile air conditioning systems by removing moisture and debris from the refrigerant circuit. Because of this, it helps reduce internal corrosion, maintain steady cooling, and extend compressor life.

This receiver drier aligns with heavy-duty mobile HVAC architectures commonly used in trucks, buses, and vocational equipment. In addition, the design supports service replacement where durability and long-term system protection matter.

Furthermore, the 74R4239 fits well in fleet and vocational environments that operate under high load and long duty cycles. Since moisture control plays a critical role in system reliability, this receiver drier helps maintain consistent A/C performance over time.

The 74R4239 also integrates easily into existing systems because it supports R-134a refrigerant and common mobile A/C lubricants. Therefore, technicians can service or replace the unit without special system changes.
