Bright 20kw 50kw customized high temperature air duct heater with temperature controller for chemical industry

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.

Composition structure: Duct type hot air heater is made of sheath house ( steel alloy, stainless steel ,or other material as your design), finned heating elements, inside with thermal insulators for keeping air temperature, wire connect box, thermocouple, inlet hole, outlet hole, temperature controller, Temperature Controller, Fuse, Overtemperature Control Device etc.

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)

We usually send the drawing for last confirmation before production.

Technical reference

1) During heating, air max temperature can reach 550 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.

The air duct circulating heater is widely used in many scientific research and production laboratories, such as aerospace, weapon industry, chemical industry and universities. It is especially suitable for automatic temperature control and large flow high temperature combined system and accessories test, drying powder, drying room, aging room etc.

The electric hot air heater is mainly used for heating from the initial temperature of the air temperature to the air flow required up to 650 °C. Has been widely used in high temperature drying, drying room, aging room, indoor and so on. Especially suitable for high temperature heaters to automatically control moderate flow. Electric hot blast stove has a wide range of applications: any gas can be heated, the heat generated by dry air is no water, no electricity, no burning, no explosion, no chemical corrosion, no pollution, safe and reliable, heating space heating fast (controlled). Electric Air Duct Heaters can meet the requirements like high temperaturedrying, drying room, aging room, room, etc., which require high temperature gases.

Electric Air Heater for the air heating process in gas or dust explosive environments. The heaters are of rigid construction with enclosed AISI 304 heater elements and are suitable for the harshest environments. The EAH-Ex series allow easy, accurate and safe control of process temperatures.
