I read about using hardware store propane as a refrigerant some time ago and have been wanting try it; however, I've seen information that says propane can be a problem. Some because it won't carry the oil through the system, and others that say it will freeze up.

It seems the commercial HC refrigerants, Duracool - Enviro-Safe, are a blend of propane and isobutane, but whether the addition of the isobutane is to carry the oil or prevent freeze-up isn't clear.

I'm just curious to know if you've experience any problem with your all propane setup.

I've used both Duracool & Enviro-safe and they worked great! The only problem is that having them shipped now incures a "hazmat charge", making it pretty expensive. The idea of using cheap, locally available propane is very appealing!

I love to know how your setup is working out. Thanks!
