I'm starting out fresh with a all new AC system, oil, drier, hoses, orifice tube. and was thinking about using this type refrigerant the 12a industrial. Anyone out there using this or know anything about it? I was told it cools 35% better than R134a and better than the R12.
Thanks

 

Basically it's propane and benzine mix which is flamable and illegal.
See this:

If you want a cold system, the biggest item is to keep the r 12 or go to 134a with a parallel flow condenser. You can also play with different flow oriface tubes.
A high cfm fan just for the condenser will help considerably.

 

I'm thinking a high CFM fan for the evap would be most useful.

 

R12 is flammable at temps lower than E12

If its illegal, then why is it being sold openly, without cover.

Use ES12A and it is great!

 

Its not illegal at all.
I've been using this refrigerant in my 1990 truck for the last 4 years and the temp at the vent swings from 38º-42º all day in 90º heat. Its GREAT stuff. Get it.

It's explained in this link:

http://www.epa.gov/ozone/snap/refrigerants/hc-12a.html

Duracool, OZ12a, ES12a and HC12a and R12a (to name a few) are all the same product marketed under different names and nothing more. It is considered a flammable (so is gas and your car has a lot more of that in it) and so is not accepted by the EPA.
So it can be sold and used just not in a mobil system.

BTW< almost all refrigerants are flamable at a certain pressure and temp.

Not everything seen or sold on the internet is 100%legal.

 

I've heard R290 works very well, better known as propane.

 

If you use R12a in your system, your insurance company will drop your policy--if they find out--and, if they find out after your wreck, they will laugh at you when you make your claim.

Since most of the refrigerant stays in the condenser--which will be pierced in almost any collision--I am sure you know what will happen.

Please don't tell me that R12 is more flammable then liquid butane. Don't even go there.

Considering all the acceptable alternatives, is it really worth the risk to use this stuff?

"...R12a is what is called a 'natural refrigerant' because it is a mixture of stable organic compounds, which have been around forever (?). It is a mixture of stable hydrocarbons to which the name 'paraffin's' was given in the early days of the study of Organic Chemistry. The mixture consists of approx. 40% butane, 59% propane and 1% ethane. Note that these materials are said to be 'highly purified' in order to use them as a refrigerant. You should not try to mix these materials out of a standard cylinder and expect that the air conditioning system will work perfectly.

It is well known that ethane, propane and butane are flammable in air and, when mixed in certain proportions with air, will burn with explosive speed. Nevertheless, propane and butane were used as refrigerants, along with ammonia, carbon dioxide, and sulphur dioxide, before the development and commercial use of freons in the early 1930's. It was an explosion involving propane in a school air conditioning system, which resulted in the death of a number of students, which lead to the banning of the 'natural' (flammable) refrigerants, in favour of the 'freons' in North America.

 

I changed over to R-134A last time I changed compressors. It runs ice cold. It's FINE.

 

I changed mine to R-134 and it works fine and is legal.

 

If I were you, I wouldn't use Envirosafe.

If I were me (how does that work), I would use Envirosafe.
