5.0 PRE-COOLER WATER CONNECTIONS
A Cooling Coil is installed in NWB-DC series dryers and is required to lower the hopper return
temperature and this increases the efficiency of dryer
IF THE DRYING TEMPERATURE IS
ABOVE 225°F .
Tower, city or chilled water is required at between 40 to 85°F. Connect the cooling water supply and
return using flexible hose that is at least 2 feet long, to allow for easy removal of the cooling coil for
cleaning. The water flow rates and the required customer connection sizes for different models are
shown in the chart below.
NOTE: Processor must use ½” ID water hose to get proper flow.
NOTE: Cooling water is required if drying temperature is over 225
°F.
The process airstream must be connected to an external cooling coil if the drying
temperature is below 170°F.
