Have used it for quite a few years now Posted by JerseySaab [Email] (#666) [Profile/Gallery] (more from JerseySaab) on Mon, 18 Jun 2012 08:20:28 In Reply to: Any suggestions for Enviro Safe, DAO, Mon, 18 Jun 2012 07:38:30 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I've been using Enviro-Safe and Duracool since R12 freon was phased out, and have used it in both R12 and R134 systems. It works quite well.
The main thing of course is to remember that you are working with a flammable material - no smoking, no sparks! Treat it as though you are working on the fuel system.
Unlike R12 or R134, Enviro-Safe is charged into the system as a liquid, with the can upside-down.
Electronic leak detectors (including those sold by Enviro-Safe!) will not detect it, unless they are specifically designed for hydrocarbons and most are not. You can use dye for leak detection - Enviro-Safe sells refrigerant containing the dye. Alternatively you can temporarily install the old type refrigerant for use with electronic detector.
Another thing to bear in mind is that once you use this "foreign" gas in your system, no garage will touch it, you are committing to servicing your own A/C.
