General Knowledge on “Duct Air Heater”

Duct air heater is mainly heated electric heating device, to be electrically converted into heat. Stainless steel electric heating element for heating, the product has a plurality of internal baffles, guide the residence time of the medium of the lumen, so that the gas is sufficiently heated evenly, improve the heat exchange rate. Internal high temperature air heater voltage system consists of metal tubes, in operation, high-temperature cycle inside the system has good thermal insulation properties of magnesium aluminum, both ends of the nozzle by a ceramic sealing silicone, structure is not only advanced, and this metal armor mounted heating element can be heated air is energy saving type air heaters, heating with excellent results.
Applications and heating range
Electric air heater is mainly used to the desired air flow is heated from an initial temperature to the desired air temperature, up to 850 ℃. Has been widely applied to aerospace, industrial, chemical industry and universities, and many research and production laboratories. Particularly suitable for automatic temperature control and high temperatures combined with high flow test systems and accessories. Electric air heaters use a wide range: any gas can be heated, dry and hot air generated by water, non-conductive, non-burning, non-explosive, non-corrosive, non-polluting, safe, reliable, space heating is heating up fast (controllable)
Technical Features
1, air can be heated to a high temperature, up to 450 ℃, the shell temperature is only about 50 ℃.
2, high efficiency: up to 0.9.
3, block heating and cooling rates, up to 10 ℃ / S, adjust fast and stable. The air temperature will not control the phenomenon of leaving the lead and lag temperature control drift uncertainty, it is suitable for automatic control.
4, good mechanical properties: it’s heating element for the special alloy, so under the impact of high-pressure air flow, it is better than any mechanical performance and strength of the heating element, which takes a long time for continuous air warming test systems and accessories has more advantages.
5, when it is not in violation of the use of procedures, durable, long service life for decades.
6, the air clean, small.
7, according to user’s needs, the design of many different types of electric air heater.
