Hi everybody,
Can anyone help on operating pressures for a three door R22 reach in beverage cooler, thanks:)

Start from the required contents temperature and work from there.

Your more than likely keeping the beverages at approximately 2 degrees celsius with a 6K evap TD. I don't know the design ambient for Mexico, but I would expect the condenser TD to be roughly 13K for a normal temp application in that part of the world. Grab your nearest pressure temperature chart and I'm sure you will work it out from there.
