The common structural feature is that the electric heating pipe is supported by steel plates to reduce the vibration of the electric heating pipe when the fan stops. The junction box is equipped with an overtemperature control device. The outer shell of the air duct usually has a 100mm thick thermal insulation material, which reduces the external heat dissipation of the entire channel and also reduces the temperature in the wiring chamber.</p></div> <div class="product-list-1"><input type="hidden" id="ProductTypeId" value="15684905" /><ul class="pro-list-0"><li class="fadeup pro-id-205906440"> <div class="product-item-img"><a href="https://www.wnh-heater.com/electric-heaters/duct-heaters/made-in-factory-air-duct-heater.html"><img src="/uploads/202333208/small/made-in-factory-air-duct-heater19b990ce-fbc2-4d13-9b7b-3ff8ec3e23f6.jpg" loading="lazy" alt="Made in Factory Air Duct Heater" /></a></div> <div class="product-item-content"> <h3 class="product-item-content-title"><a href="https://www.wnh-heater.com/electric-heaters/duct-heaters/made-in-factory-air-duct-heater.html"><span>Made in Factory Air Duct Heater</span></a></h3> <p class="product-price"></p> <p class="product-item-content-text">An air duct heater shall be installed into a round duct after the incoming air filter, before HRV unit inlet.
