Wow, my brother's graduation party was today and I happen to have a cuz who is an HVAC electrician. How convient is that? He hooked my up with some free stuff.

-Pressure guages
-Vacume Pump
-Some cap tube

He also told me he can get me any gas I want. Everything from R22 to R1150. Sweet beans man. Also he wanted to help with my chiller and came up with some great ideas. He has this res at his work that is a large steel tub and it has fittings in it for the evaporator and also for in and out of the collant. Also it's air tight. Also he said he could mount on it small LCD readers that read the coolant temp, evaporator temp and Incoming coolant temp. Isn't that really sweet? Well anyways this post does come with a question. Does anyone know some good replacement refridgerants for R12? Something a tad colder. I know R134 does it, but is that it?

R12 compressors are filled with mineral oil. Without changing oil, you could use R22, R408A, or R402A. For R404A or R507, you would need to change the oil to POE.
