Cold rail evap temp.

[KB Cool]

Are these considered low temp or med temp?

Come on guys! Nobody works on these? If i throw my gauges on one, should i see PSI's that relate to a freezer or a cooler? Thats all i'm asking.
Thanks

They would be considered medium temp applications. The ones I've seen run between 0ºF and +10ºF evaporator temps for the drop-in style and a bit higher if you're talking about a raised rail on a prep table.

The ones I came accross run like a freezer.
Usualy subway sandwich tables and also continental coolers with rail section are the ones I work on.But I can't remember the pressure range off the top of my head right now.:o

The prep tables at Subway that I have worked on are manufactured by Duke. They are charged with 134a and run between 0-4psi on the low side.

I recollected continental refrigeration rail section lpc settings ; 45 psi,25 diff.-404a. no fan in the rail.I heard they manufacture the new ones with fan so I don't know the settings for that..

Thanks guys. We have a new customer that has bunch of these things, both rail and drop-ins. No problems w/ any of them so far. But, when the time comes. I wanna at least have a clue of what i'm looking at.:D
