Working principle

Duct type auxiliary electric heaters are mainly used for heating air in ducts, with specifications in three forms: low temperature, medium temperature, and high temperature. The common structural feature is the use of steel plates to support electric heating tubes to reduce vibration when the fan stops, and the installation of super temperature control devices in the junction box. The low-temperature type can be directly installed on the air duct, while the medium temperature type and high-temperature type, due to structural differences, have a 100mm thick insulation material sandwiched between the outer wall of the channel and the heater junction box, which reduces the external heat dissipation of the entire channel and also reduces the temperature inside the junction box.

Product Features

1. The electric heating tube adopts an externally wound corrugated stainless steel strip, which increases the heat dissipation area and greatly improves the heat exchange efficiency.

2. The heater design is reasonable, with low air resistance, uniform heating, and no high or low temperature dead corners.

3. Double protection, good security performance. A temperature controller and fuse are installed on the heater, which can be used to control the air temperature in the air duct to work in extremely warm and windless conditions, ensuring that everything is foolproof.

4. Uniformly distribute high-temperature resistance wires inside the seamless stainless steel tube, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. This structure is not only advanced and has high thermal efficiency, but also generates uniform heat. When current passes through the high-temperature resistance wire, the heat generated diffuses to the surface of the metal tube through the crystalline magnesium oxide powder, and is then transferred to the heated element or air, achieving the purpose of heating.
