風道加熱器主要用於風道中的空氣加熱，規格分低溫、中溫、高溫三種形式，在結構上的共同之處是採用了用鋼闆支撐電熱管以減少風機停止時電熱管的振動，在接線盒中都裝有溫控製裝置。低溫型可直接安裝在風道上，而中溫型、高溫型由於結構上的不同，在通道外壁至加熱器接線盒夾有100mm 厚的保溫材料，一方麵減少整個通道的對外散熱，另一方麵也減少了接線腔內的溫度。
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.
