Calculated in tons of BTUs at 50°F leaving water temperature—For every 1°F below 50°F a chiller losses 2% of it's tonnage.
†† A standard system uses 2.4 gpm to create a 10°F rise across heat exchange surfaces.
Air rings require 42°F water
‡‡ Extrusion system calculations are based on using heat exchangers and no direct bath contact.
