Sandwich bar sweating badly.

[mlock]

Have an r-22 sandwich bar sweating profusly. What kind of evap temp should I be running and what about sh? It has a single evap w/dual fans that blow the air up from the refrig compartment to the sandwich bar.
Thanks

Lowest coil temp should be around 20F with evap cycling above freezing during temp satisfaction phase or during defrost long enough to melt any ice accumulation on evap fins. Are the gaskets ok? Is room temp under 86F(?), and they must keep the lid down for proper temp and moisture control between uses. It's built for the lid to stay closed whether it's a pain fopr them or not. you can only control the machine not the customer!

Also consider that the dew point in space is excessively high. 75^F, 50%RH, 55^F dew point space conditions means that if the surface temperture of the sandwich bar is below 55^F, the surface will be wet. Lowering the dew point of the air around the bar or raise the temperature of the bar a couple degrees are solutions. Increasing dehumidification by the a/c requires lower air flow and a colder a/c coil is a possible solution. Adding a good dehumidifier like the Ultra-Aire is solution if your a/c is not operating enough to lower the dew point.

Thanks you. I think it's more of a drain issue, just wanted to rule out anything in the refrig cycle. Replaced the pan a couple yrs ago, but new one wasn't 100% o.e.m. so had to use duct tape to rig it. Thanks again.

DUCT TAPE! tHE BANE OF ANY GOOD TECH. Anything worthy doing is worth doing right.
