Air heater is an electric heating equipment which mainly heats the gas flow. The heating element of the air heater is a stainless steel electric heating tube. The inner cavity of the heater is provided with a plurality of baffle plates to guide the flow direction of the gas and prolong the residence time of the gas in the inner cavity, so as to fully heat the gas, heat the gas evenly and improve the heat exchange efficiency. The stainless steel heating pipe of the heating element of the air heater is formed by shrinking the pipe after the electric heating wire is installed in the seamless steel pipe and the gap is filled with magnesia powder with good thermal conductivity and insulation. When the current passes through the high-temperature resistance wire, the generated heat diffuses to the surface of the heating tube through the crystalline magnesia powder, and then transfers to the heated air to achieve the purpose of heating.

        The electric air heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850 ℃.

        Technical features

        1. It can heat the air to a very high temperature, up to 450 ℃, and the shell temperature is only about 50 ℃.

        2. High efficiency: more than 0.9.

        3. Heating and cooling rate block, up to 10 ℃ / s, fast and stable adjustment. The temperature control will not drift due to the leading and lagging of the controlled air temperature, which is very suitable for automatic control.

        4. Good mechanical performance: because its heating body is made of special alloy material, it has better mechanical performance and strength than any heating body under the impact of high-pressure air flow, which is superior to the test of systems and accessories that need to continuously heat the air for a long time.

        5. It is durable and has a service life of up to several decades when it does not violate the use regulations.

        6. Clean air and small volume.

        application area 

        The application scope of heater. Air heater is a widely used heater. We commonly call it air heater. In fact, it can be divided into many types according to different heating gases. The common ones are nitrogen heater and hydrogen heater. These can also be called pipeline gas heaters. It has been widely used in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry and colleges and universities. It is especially suitable for automatic temperature control and large flow high temperature combined system and accessory test. The electric air heater has a wide application range: it can heat any gas, and the hot air produced is dry, non-conductive, non combustible, non explosive, non-chemical corrosivity, no pollution, safe and reliable, and the temperature of the heated space is fast (controllable).
