A/C Receiver Drier / Accumulator The Receiver-drier must be changed each time system is empty regardless of reason for loss of refrigerant. This item should be changed every three years because desiccant pellets break down and will clog the expansion valve and may damage the compressor.
It is a disposable item to be thought of in the same terms as a fuel, oil or air filter. Anytime a component fails or is replaced replace the receiver-drier to prevent moisture or corrosion within the system.
We stock driers to ship with compressors. We take pride in supplying quality units and make every attempt to supply units made by the original OEM manufacturer.
