Differences in cooling units.

[loman4ec]

I was just wandering if there is any differences in cooling units from any machine from the 60's and 70's. They all look the same to me. I am wandering because I have passed up many machines due to bad compressors but I have found a junk machine that cools good that I can have if I want it. It is a late 70's Pepsi machine. I don't know the make or model but it is really big, tall, and ugly. Also when you take out a compressor do you have to re charge the coolant? I'm sure that you all can tell that I am a novice now. I guess what I am asking is should I bother the hassle of getting this machine to gut the compressor out of it? Thanks for your help. Josh

There are so many makes and models of soda machines, and their cooling units, from the 20's through today, that I have problems keeping them straight, I've done nothing but refrigeration, exclusively, since 89'. Best to start with a like brand, Vendo, Cavalier, Westinghouse, etc. Now remember this doesn't mean that the refrigeration system will swap out, but the compressor itself may. At this point, it may be best to have someone in the business do the work for you, if you're not experienced in refrigeration. When looking for a unit, the most important thing is the hp rating, 1/3, 1/4, 1/5, 1/6, etc.
If they match, there shouldn't be a problem.
