Duct heater is mainly used for air heating duct, to specification and low temperature, medium temperature, high temperature in three forms, the common structure is a steel plate support the heating tube to reduce the vibration of the fan stops the heating tube, The junction box is equipped with over-temperature control device. Low temperature can be directly installed in the ducts, while the medium temperature, high temperature due to structural differences in the channel outer wall to the heater junction box to the folder with 100mm thick insulation materials, on the one hand, to reduce the external cooling of the entire channel, it also reducing the junction temperature of the cavity. 

 Duct heater Features 

 A. Electric heating tubes around the outside corrugated stainless steel band, increasing the cooling area, greatly improving the efficiency of heat exchange. 

 Two. The heater design and low wind resistance, uniform heating, no high and low temperature dead ends. 

 3. Dual protection, good safety performance. Installed in the heater, thermostat, fuses can be used to control the duct air temperature ultra-mild case of no wind to ensure foolproof. 

 Product Application: heating the air, for a variety of different substances in the drying / curing, heat treatment, re-heating and dehumidification, and other similar applications.
