Uniformly distribute high-temperature resistance wires inside high-temperature resistant stainless steel seamless pipes, and fill the open ground with crystalline magnesium oxide powder with excellent thermal conductivity and insulation functions. The layout is not only leading, but also has high thermal efficiency and can generate heat evenly. When there is current passing through the high-temperature resistance wire, the heat is dispersed to the surface of the metal pipe through the crystalline magnesium oxide powder, and then transferred to the heated component or air to achieve the purpose of heating.

The air electric heater is mainly used to heat the required air flow from the initial temperature to the desired air temperature, with a maximum of 850 degree . It has been widely applied in many scientific research and production laboratories such as aerospace, weapons industry, chemical industry, and higher education institutions. Especially suitable for active temperature control, high flow and high temperature combined systems, and accessory experiments. The application scale of air electric heaters is wide: they can heat any gas, and the hot air generated is dry, non-conductive, non incinerable, non explosive, non chemically corrosive, pollution-free, safe and reliable, and can quickly heat up the space.
