Receiver Dryer: Description and Operation

Receiver Drier







The receiver drier acts as a refrigerant reservoir for the system. Any moisture in the system is absorbed in the drier desiccant.


CAUTION!
The receiver drier may be identified with a green R-134a label and MUST NOT be used in R-12 systems (the drier desiccant inside is only compatible with R-134a refrigerant). Likewise, NEVER use an R-12 receiver drier in and R-134a system.
