INSTALLATION
CAUTION: FOLLOW ALL NATIONAL AND LOCAL ELECTRICAL AND MECHANICAL
CODES, AS REQUIRED. ONLY QUALIFIED AND TRAINED PERSONNEL
SHOULD INSTALL AND OPERATE THIS EQUIPMENT.
5.1 Location
Locate your NWB Series dryer in a low traffic area, this will avoid disturbance of the
hoses connecting your dryer to the hopper. Allow sufficient distance (at least 2 feet) from
the surrounding equipment, so the access doors may be opened to perform routine
maintenance on the dryer and for safe operation.
There must be a grounded power source that will supply the correct voltage per the dryer
nameplate.
Water (tower or chilled at +45 to 85°F) must be supplied to the cooling coil using flexible
hoses.
5.2
Customer Piping Connections
Care should be taken while connecting the process air piping. If hoses are used, it should
suitable for at least 350°F and silicone hose is recommended. On larger piping, hard
piping with steel tubing should be considered. The piping should not block the access
doors of the dryer. See below for the correct connection size from the dryer to the
hopper.
Process air connections:
NWB-25:
2 inches diameter
NWB-50:
2 inches diameter
NWB-75:
2 inches diameter
NWB-100: 4 inches diameter
NWB-150: 4 inches diameter
NWB-200: 4 inches diameter
NOTE:
On smaller hoppers, we introduce the
process air about midway up the
hopper and pipe it down to the bottom
of the hopper through a diffuser cone
that spreads to heat evenly.
