110/220/380V Industrial Steam Boiler High Temperature Electric Heating

Air duct heaters are composed of open coil, tubular or finned tubular heating elements that are either flanged or inserted in the duct. we supply two types of duct heaters: air duct heaters and process heaters. Air duct heaters are primarily used in air flowing ventilation systems and comfort heating applications while process duct heaters are mainly used for industrial process heating applications (ovens that require re-circulated air or forced circulation). we design and configure your electric duct heaters according to your specifications. Our team is dedicated to research and development of the latest technologies, while striving to meet every customer's needs by manufacturing first class duct heaters. Our 10-year expertise in developing and manufacturing electric duct heaters make our heaters the most easily adaptable solutions for most nonpressurized air-heating systems.

Temperature range:

Low temperature: less than 160 degree Celsius (insulators thickness: 80mm)
Middle temperature : from 160 degree Celsius to 200 degree Celsius (insulators thickness:100mm to 150mm)
High temperature: from 200 degree Celsius to 650 degree Celsius (insulators thickness: 300mm)

Advantages:

1. During heating, air max temperature can reach 650 degree Celsius, but the surface temperature of the shelth 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 5-10 years.
6. Clean air, small volume.
7. Made as client design.
8. After reached the max temperate, the working wattage can reduce to half .
