Product Details

The Denso 478-2010 receiver drier is part of Denso’s New Receiver Drier line, which focuses on OE-style A/C service components made to factory-level standards. In an automotive air conditioning system, the receiver drier helps regulate refrigerant movement while removing moisture that can contribute to corrosion, internal wear, and leaks. For Mercedes-Benz S500 and related chassis applications, replacing the receiver drier during major A/C service is a standard maintenance step when the system has been opened or repaired.

This part cross-references Mercedes-Benz 140 830 01 83 for the same application.

What It Helps Address

• Moisture contamination inside the A/C system
• Corrosion affecting internal HVAC components
• Reduced refrigerant flow stability
• Surging or inconsistent A/C operation
• Premature wear after major air conditioning service
