Specifications

 Air duct heater is used to heat up the gas in the gas duct and it's suitable for a lagre amount of wind duct. Its max teperature is 300 °C.

 Electric air duct heater  is mainly used to heat up the air in the air duct,which can be classified into three types:high temperature, medium temperature and low temperature.

They have something in common:

1.their structure is designed with steel plate to support the heating tube to reduce the vibration of the heating tube

 when the fan stops working.

2.The over-temperature controller is installed in the Junction box.

The low temperature type air duct heater is directly installed on the airduct, while the medium temperature

type and high temperature type,each of them has a 100mm  thermal insulation material between the outer wall

of the channel and the heater Junction boxdue to the diffrent structure. Thus, on the one hand, it reduces the

external heat dissipation of the whole passageway, on the other hand it also decreases the temperature in the

wiring chamber.

 Characteristics:

1.Heating tube adopts outer coiled ripple-type SS belt thus,it greatly improves the Heat exchange efficiency.

2.Professional design,

3.low wind resistance,

4.uniform heating,

5.no high temperature or low temperature blind angle.
6.Duplex protection,good safety performance.Temperature controller and fuse protector are installed,which

can be used for controlling the heater operates normally under the condition of overtemperature and without

wind,thus,to guarantee Not a single miss in a ten thousand times.
