No oil :D

Oiless pumps are made for recovery of refrigerant. I have one. Not too sure how it works. But. If you could figure a way to pump refrigerant with out oil, you could really change some things about this industry. I wonder what the future holds for our equipment designs.

Ben and Jerry's Ice Cream magnet refrigeration study is pretty interesting but just not feasible.

Doesn't the oil in the refrigerant lubricate the oiless pumps?

I spose hey?

A few years back there was an article about the advantages of oil separators in a refrigeration system. The author climbed that if you didn't let oil out into the system you could reduce energy consumption. He claimed that oil coated the inside of the tubing which reduced heat transferrence. Also the oil took up space thereby reducing the amount of refrigerant that could be in the system.

So yes a compressor that didn't need oil would be a good idea IMO also.

no oil needed for these compressors.....TURBOCOR

Yeah, and ya have to be careful sometimes.
This reclaim stuff is not only a cash cow for some big corps but a load of crap for all of us.
