Fermo Vending Posted April 24 Share Posted April 24 Are the 501e and 276e originally charged with R-12? Link to comment Share on other sites More sharing options...
AZVendor Posted April 24 Share Posted April 24 They all have R134 to my knowledge. You can search the model of the compressor (on the side of it) and see what oil it's charged with to determine which gas is in it. Link to comment Share on other sites More sharing options...

Can’t seem to find an affordable or size able can of M39 anywhere. Is it an old Freon not regularly used these days? Link to comment Share on other sites More sharing options...
AZVendor Posted April 24 Share Posted April 24 You have to buy a 30 lb cylinder of MP39. It was never sold in one pound cans. It also could be dropping by the wayside too. Link to comment Share on other sites More sharing options...
orsd Posted April 26 Share Posted April 26 If you don’t have R12 machines no point in buying MP39. R134a is way cheaper and more plentiful. Link to comment Share on other sites More sharing options...
Fermo Vending Posted April 26 Share Posted April 26 Makes a lot of sense. I'll have to inventory the type of refrigerant in all of my machines. Thanks fellas. Link to comment Share on other sites More sharing options...
AZVendor Posted April 26 Share Posted April 26 If you're wanting to do your own recharging on all of your machines then just get the MP39 even if it's more expensive than R134a because then you can recharge them regardless of the gas that is in them.

I disagree with you on that one. Keep R134a machines R134a. R12 machines that are still running R12 are becoming rarer and rarer. No point in dropping in expensive refrigerant just in case you have an R12 machine still running R12 that needs a charge. At this point most R12 systems have been converted to R134a, junked, or are needing a compressor (and conversion to R134a anyways) soon anyways. In addition, MP39 is a blend, so you have to charge it as a liquid, can’t just charge it as a gas through the low side service stub on the compressor. So it’s easier to charge with R134a than MP39. Also, MP39 is also known as R401A, might have an easier time finding small containers if you look for that (401a, NOT 410A) Edited April 26 by orsd Link to comment Share on other sites More sharing options...
Fermo Vending Posted April 26 Share Posted April 26 I hear your point but the prices I was seeing were WAY higher than R134a, and I have almost all dixie narco 276e or 501es at this point in my vending career, so that could be a move for down the line Link to comment Share on other sites More sharing options...

Just buy R134a and cross the MP39 bridge if and when you need to. Link to comment Share on other sites More sharing options...

AZVendor Posted April 26 Share Posted April 26 orsd, You can charge through a charging port with MP39 if you simply turn the can upside down before you open the valve. That's how we did it for years with no issues. Well, other than if we recharged a machine more than 2 times, then we had to evacuate it and charge by liquid weight so that the oil quantity was correct. Of course, by the time you have to recharge a third time you should be finding the leak too. Link to comment Share on other sites More sharing options...

Yes, technically you can charge liquid through the low side if you throttle it slow enough that it turns into vapor before it hits the compressor, but that’s a risky game that isn’t ideal.

AZVendor Posted April 26 Share Posted April 26 That's how we built and charged new compressors and how we recharged used ones back in the day. Link to comment Share on other sites More sharing options...
