Overview of Duct Heater
Duct heater is mainly used for heating air in ducts. It is available in three specifications: low temperature, medium temperature, and high temperature. A common structural feature is the use of steel plates to support the heating tubes, reducing vibration when the fan stops. The junction box is equipped with an over-temperature control device. The low-temperature type can be directly installed in the duct, while the medium and high-temperature types, due to structural differences, have a 100mm thick insulation material between the outer wall of the duct and the heater junction box, which reduces heat dissipation from the entire duct and also lowers the temperature inside the junction box.
Structure of Duct Heater
1. The duct heater uses stainless steel heating tubes as the heating element.
2. The bracket is made of carbon steel or stainless steel.
3. It is constructed using a modular connection method.
Product Features of Duct Heater
1. The electric heating tube is wrapped with corrugated stainless steel strips, increasing the heat dissipation area and greatly improving heat exchange efficiency.
2. The heater is well-designed with low wind resistance, uniform heating, and no high or low temperature dead spots.
3. Dual protection ensures good performance. The heater is equipped with a thermostat and a fuse, which can control the duct air temperature and ensure safe operation even under no-wind conditions, guaranteeing reliability.
