风道加热器主要用于风道中的空气加热，规格分低温、中温、高温三种形式，在结构上的共同之处是采用了用钢板支撑电热管以减少风机停止时电热管的振动，在接线盒中都装有超温控制装置。低温型可直接安装在风道上，而中温型、高温型由于结构上的不同，在通道外壁至加热器接线盒夹有100mm 厚的保温材料，一方面减少整个通道的对外散热，另一方面也减少了接线腔内的温度。
Duct Heater is mainly used for heating the air duct, specifications at low temperature, medium temperature, high temperature three forms, common in the structure is the use of steel plate to support heating pipe heating pipe to reduce vibration when the fan is stopped, junction boxes are equipped with over-temperature control device. Low temperature can be mounted directly to the duct, and the medium temperature, high temperature due to the different structure of the outer wall of the channel to the heater junction box sandwiched 100mm thick insulation materials, while reducing the external heat throughout the channel, it also Less wiring cavity temperature.
