Morphing Air Conditioner into Autocascade System

[wdrzal]

Bernzomatic is 97.5% according to them, other stuff is HC's and air in small quantities. Run through a filter on the way in. I use that and its more then pure enough to run full singles and cascades on 290 only.

How about a explanation of the law in the USA of using propane in refrigeration systems..........or pure HC's. It's actually illegal to modify(say a torch) to use it other than for it's intended purpose.


Are refrigeration units being designed/built to satisfy all the regulatory bodies,Or are potential bombs being built.

Even systems designed with every safety precaution possible/thinkable occasionally things still go boom "$hit happens" doesn't get you a "Get out of jail free card".

I don't know......... Once you start selling/shipping units you just opened yourself up to exposure from all government regulations.


What do you guy's Think ??????
