<VV> A/C For 69 Corvair

[jvhroberts at aol.com]

 Also incorrect, ES12 does burn, R12 and R134a are non flammable and non combustible. 

Anytime you change the pressure in the system by any significant amount, nothing is optimized anymore.

Bob:  I don't think this is a problem.  The ES12a (hydrocarbon gas) has a higher 



ignition temp than both R12 or R134a, and is non-toxic.  Also, it requires lower 



pressure on the A/C components and less horsepower from the engine to run the 

compressor.



As I said, I ran it without problems in my other car, and I like the idea that 

it's non-corrosive when contacting moisture...Bill

Isn't Envorosafe propane based? 



And wouldn't that be highly dangerous to use around spark ignition engines?



And wouldn't it be unsafe to use in Corvairs?
