Recovering refridgerant

Ga hotdog on Sun July 27, 2008 1:14 PM User is offlineView users profile

Year: 2000
Make: Chrysler
Model: Town- Country
Engine Size: 3.8
Refrigerant Type: 134
Ambient Temp: 90
Pressure Low: 30
Pressure High: 250-300
Country of Origin: United States

Question is in recovering refridge what if there is air and moisture in it along with refridgerant does all that go back in when you recharge with it? I'm new as you can tell, just trying to learn. Also I've had AC trouble on my town and country the last few months and replaced the dryer twice and no oil came out of the old ones, is that normal or does it say I may be low. Had compressor replaced last year and service man said he put in correct amount.

Accumulator/drier should retain some oil. Replacement twice with no signs of oil I would think you could be low on oil.

With proper reclaiming equipment there should be no issue with moisture or air in your reclaimed refrigerant.


When considering your next auto A/C purchase, please consider the site that supports you:

There are 3 classes of recovery operations.

Recover -- Remove the refrigerant from the system and put it in a tank with no processing. This refrigerant really shouldn't be reused before further processing such as reclamation, but a DIYer can put it back into the same car if it is known to be clean. The plain "recovery machine" does this.
Recycle -- A more elaborate machine passes the used refrigerant thru filters to remove water and particles, and removes air. Does not resolve situations such as mixed refrigerants or hydrocarbon contamination.
Reclaim -- Complete chemical purification and testing to meet purity standards. This refrigerant can be packaged up and sold as "new." Usually done off-site at a factory.
