Air heaters use metal to generate eddy currents in an alternating magnetic field to generate heat and are usually used in metal heat treatment. The principle is that when a thick metal is in an alternating magnetic field, a current is generated due to electromagnetic induction. When a thick metal generates a current, the current will form a spiral flow path inside the metal, so that the heat generated by the current flow is absorbed by the metal itself, which will cause the metal to heat up quickly.
The electric air heater is mainly used to heat the required airflow from the initial temperature to the required air temperature, up to 850 ℃. It has been widely used in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry, and universities. Especially suitable for automatic temperature control and large flow high temperature combined system and accessory test. The electric air heater is used in a wide range: it can heat any gas, and the generated hot air is dry without moisture, non-conductive, non-flammable, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space heats up quickly Controllable).
