Dear Guys,

Need your help. We are planning to install a tray tunnel freezer with 380kW refrigeration load (2 evaporators). We are looking for option to install a stand alone ammonia refrigeration system which is a packaged chiller operating at -40/+38 degC. This package chiller composed of screw compressor, LP Vessel, Ammonia Pump and condensing unit.

My issue is if the stand alone refrigeration unit enough to supply hot gas defrost for the tray tunnel freezer evaporators. Any thought? Thanks
