Overview, structure and characteristics of air duct electric heater

Overview of air duct heater

The air duct heater is mainly used for heating the air in the air duct. The specifications are divided into three forms: low temperature, medium temperature and high temperature. The common feature in the structure is that the electric heating pipe is supported by steel plate to reduce the vibration of the electric heating pipe when the fan stops. The over temperature control device is installed 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 have a 100 mm thick insulation material between the outer wall of the channel and the junction box of the heater due to their different structures. On the one hand, it can reduce the external heat dissipation of the whole channel, on the other hand, it also reduces the temperature in the wiring chamber.

Structure of air duct heater

1. Stainless steel heating pipe is used as heating body for air duct heater

2. Use carbon steel or stainless steel as support

3. Combined connection mode is adopted

Product features of air duct heater

1. The electric heating pipe adopts corrugated stainless steel belt, which increases the heat dissipation area and greatly improves the heat exchange efficiency.

2. The heater design is reasonable, the wind resistance is small, the heating is uniform, and there is no dead angle of high and low temperature.

3. Double protection, good safety performance. A temperature controller and fuse are installed on the heater, which can be used to control the air temperature of the air duct to work under the condition of no wind, so as to ensure safety.
