Convert freon/change cap tube

<< < (2/2)

Eric,

I do have the compressor tag. I'll have to look at it this weekend.

On a similar note, I'd like to understand why it wouldn't be easier to put in a thermostat for 38 degs, rather than change the cap tube. Any thoughts on that?

Also, any rough estimates on how much freon a system from a small freezer would require (I know its less than 5 lbs, but not sure how much)?

Lastly, any advice on HotShot or Autofrost X4?

globalcompressors:
I really don't have any advice pertaining to the use of an aftermarket R12 replacement. In the vending industry, we have gone over to R134a. I don't have any idea about the others, sorry. If you wanted to use 134a, the pressure on your
low side guage, in a factory low temperature unit, will run -3 to -5 psi in a hot box. That should be close enough for cooling to take place. Again, just guessing, the amount of freon will probably be in the 4 to 6 oz. range. It depends on the size of the coils, the physical size of the compressor and whether or not there is an accumulator. If you changed anything from the original design, I really won't have any useful info though. Everything I told you is based on factory and my experience. As far as just a simple thermostat change, hey, try it! It might work. The only "custom" units I have built, have been for antique soda machines. Of course using the proper parts, coils, etc. for what ever size I'm working with. Good luck!

Eric
