CO 2 cooling decks

[57thTom]

The technition was putting selection buttons on the DN 501 E this afternoon and he told me that Coke and Pepsi machines come with CO 2 or propane cooling decks now. He is from the local Canteen franchise, so he would know.

Has anyone else heard of that? Won't that make life difficult for independent vending operators in a few years?

In our area they switched to co2 last year but are now sending out kits to switch them back to r134a decks. The co2 compressors are more difficult to work with.

This guy said the carbon dioxide decks only last 8 months. It sounds miserable.

You can thank your government for this all vending machines will be switching to propane or Co2 soon (by 2020) due to an EPA mandate that outlaws 134a and others refrigerants.

It's quite convenient for the refrigerant mfg's actually.

Every 20 years it seems like the current refrigerant is found to be raping the earth.

Coincidentally, patents last 20 years.

And there is always a new refrigerant that will save all the harp seals, but it just so happens to be patented, like R 1234yf.

It also seems like the decks go bad faster and faster and the refrigerant is less and less effective.  I don't know if that applies to co2.  Fortunately, it's completely non-toxic so, assuming it's pure co2, I would like to believe that it will theoretically become cheaper to service and recharge but I literally don't know golpher.

What does it cost to transition a machine to CO2 or propane?

[orsd]

Why?

Co2 decks are less reliable than regular R134 decks.

You cannot retrofit R290 (propane) in a machine not built for it, as they have special features to prevent propane explosions. If the deck explodes your golpher is toast legally.
