Electric Air Duct Heaters uses electric power as energy to convert electric energy into heat energy via electric heating element. Hot Air is circulated in the system through Air Blower, and circulating Air heating is used. Electic Air Duct heaters are energy efficient alternative to conventional Wood/Coal/Gas heaters.
Conventional Wood/Coal/Gas heaters need large storage space for heating equipment, manual labor area and large storage area (for wood or Coal) whereas Electric Air Duct Heaters are smaller in size and can be implemented/used in small spaces.
Conventional Wood/Coal/Gas heaters require additional equipment's to reduce pollution and be compliant with local pollution policies. Electric Air Duct Heaters doesn't pollute the environment and therefore environment friendly.

1) During heating, air max temperature can reach 500 degree Celsius or higher temperature, but the surface temperature of the sheath is just around 50 degree Celsius
2) Heat efficient is more than 95%
3) Temperature raise rate : 10 degree Celsius per second during working
4) The heating elements is made of high temperature alloy with good mechanical character
5) Usage time: standard more than 10 years
6) Clean air, small volume
7) Made as client design (OEM)
8) After reached the max temperate, the working wattage can reduce to half
9) The electric heating pipe is made of corrugated stainless steel strip, which increases the heat dissipation area and greatly improves the heat exchange efficiency.
10) Reasonable design of heater, small wind resistance, uniform heating, no high or low temperature dead angle.
11) Double protection, good safety performance. Temperature controllers and fuses are installed on the heater, which can be used to control the temperature of the air in the air duct and work without wind, so as to ensure that there is no mistake.
