My boss has come up with the idea of placing a digital pack r404a (single scroll compressor) on a small system comprising of a 4 door and 3 door undercounter fridges, chiller coldroom 3m x 1.8m x 2.3m all running around +2/+5 degrees c which is fine. The only problem is he wants a 3m saladette table top also to run on this system.
I think that as its a static coil the evap pressure will be a lot lower but not sure around -15 as opposed to -5 on other units. Firstly does this sound right and secondly would there be any problems caused by this??

Cheers for any help with this
