Freeze-12, alternative R-12 refrigerant
This week I will attempt a charge of an SVX R-12 system with an alternative called Freeze-12. I was preferring to find and use a differnt alternative called Hotshot (aka R-414b) but my search for it locally has come up empty. I will post my results, possibly with pictures, when completed.

I'm using Freeze12 in mine, I've seen a few others posting about it too. It goes by a few different names though...

I hear propane is a great refrigerant. Supposedly its used in 3rd world countries and performs better than r12 or r134.

There is not very much gas in an A/C system, certainly not enough to make a very big explosion and there are plenty of other flammable fluids in the engine compartment. Some cars over here run even on LPG. Some people drive camper vans with propane/butane cookers in them. In Europe, particularly Germany, R600a gas (isobutane) is commonly used in cars and it is somewhat similar to propane. I wouldn't be at all worried about using propane/butane/isobutane in my A/C system. I use RS24 (an R12 substitute) in the 92 and R134a in the 94. Unfortunately both cars have leaks and need topping up, but A/C is not really required in England this summer.

Is cost the reason folks seem reluctant to use R134a? I've been using it in my teal SVX for four Georgia summers now with excellent results (and zero maintenance), so I'm curious as to why anyone would seek an unproven alternative. The silver is still running R12 (so far as I know), I alternate days driving them, and there's no discernible difference between the two in cooling output.

Also: interesting tidbit about R12/R134A. Dupont chemicals invented R12, back in the day, and acquired a patent on it. As you know, patents only last only 20 years. Well, 20 years later, anybody could make R-12 without having to pay dupont chemicals massive royalties. Soon thereafter, Dupont's own scientists 'discovered' how harmful R-12 was, and pushed for it to be made illegal to produce. Instead, we now use R-134A, a coolant that is actually MORE corrosive and MORE damaging to the environment. Anybody want to guess who owns the patent on this new one? :P

Well, I used the $29.95 AutoZone "retro fit kit" on my car and charged it with R134... and it works PERFECTO, its even colder than before. The only problem is that it was overcharged and when the arizona heat goes over 110 the pressure builds up so much that the compressor stops.... but I just need to take it to the shop and recharge it with less r134 than before.
R134 its actually environment "friendly", its mineral based and it doesnt harm the ozone layer either the soil. You can actually breath it and you wond die of poisoning.... you can die for lack of oxygen, but its not bas as R12. |

Then how come it corrodes the rubber seals on older R-12 equipment?
