melobyrro1 Posted May 6, 2016 Share Posted May 6, 2016 Hi all, i need some help on how to choose the right compressor for vending machines, can anyone clarify some of the specs and when it is important? for most sodas machines probably 1/3hp is fine, but what does + mean? is there a way to calculate the compressor ill need? but how important is BTU? how is it gonna affect it? there are compressors with less btu more hp and vice versa, whats the correlation?

Walta Posted May 6, 2016 Share Posted May 6, 2016 If you are replacing a failed unit it is best to read the numbers from the stamped steel tag welded to the top of the compressor. Then order the correct part. The fact that you are asking this question, leads me to believe you do not have the required federal license and or knowledge to do this job.

Walta No, i dont, like many in this area, I understand to replace it with same part number, but im looking for more knowledge, What im looking to do is convert a AMS combo, that can do frozen, to do only sodas, the compressor is bad, i want to learn how to calculate what type of compressor i need, the volume of machine, size of evaporator, and find out btu and hp needed. OEM compressor is $400 luckily the modern world we live in we have more access to information, and we dont need to be attached to old system of having to pay enormous amount of money to learn anything. thus, it uses r134, no harm to environment, and force someone to spend money for a license that all competition dont have isnt viable. how many auto mechanics that work on car a/c have license? i ask around they laugh...

AZVendor Posted May 7, 2016 Share Posted May 7, 2016 If you can get an OEM AMS condensing unit for $400 then it's probably used or rebuilt not "OEM." Rebuilding a cooling deck now is over that price most of the time and factory new units are usually $600+. The frozen AMS uses a 1/2 HP compressor. The chilled snack uses a 1/4 HP compressor which is too small for a VCB model (bottles). The VCB model also uses a 1/2 HP compressor. The real problem is that your frozen model uses a completely different design of condensing unit that fits only that model cabinet. I think you will pay way to much to convert it over to a low temp version. Look at the two parts manuals, VCB and Frozen, and you'll see the vast differences between the two machines and how many parts would need to be changed, if you can even change them. Your best bet would be to call AMS tech support and ask if this even makes sense to try - I don't think it does. Link to comment Share on other sites More sharing options...
