The Caloritech™ WXL Process Duct Heater is designed for installation in process ducts to heat air or other non-hazardous gases. It features a steel mounting plate, terminal box and stainless steel element support plate. The heater is inserted into a duct through a hole and secured with suitable bolts, studs or screws.
Please note that all process duct heater installations must include a device such as a thermocouple control or proximity high limit cutout to limit the outlet temperature in the event of fan failure or malfunction of the process temperature regulator.
