Receiver Dryer for Car Air Conditioning | Valeo Service

The receiver drier is a critical component in protecting the A/C loop, positioned between the condenser and the expansion valve on the high-pressure side. It performs essential roles, including:

• Retaining moisture and contaminants from the system.
• Finalizing the condensation of the refrigerant fluid.
• Compensating for variations in fluid volume.
• Ensuring oil return to the compressor.

Regularly replacing the receiver drier prevents costly failures and protects other A/C components. It must be replaced whenever the system is opened, for example, after an accident. Failing to replace it can lead to blockages, impurities, and deteriorated system performance.

Replace the receiver drier every 3 years to ensure optimal performance. During replacements, install the receiver drier at the very last step before the vacuum procedure.
