Air electric heaters are devices used for heating air. In ventilation and air conditioning systems, hot water, steam, or electricity are commonly used as heat sources.

Air electric heaters are primarily used to heat the required air flow from an initial temperature to the desired air temperature, up to 850°C. They have been widely applied in aerospace, arms industry, chemical industry, and many scientific research and production laboratories in colleges and universities. Particularly suitable for automatic temperature control and high-flow high-temperature combined systems and accessory testing. The range of air electric heaters is extensive: capable of heating any gas, producing dry, moisture-free, non-conductive, non-flammable, non-explosive, non-corrosive, non-polluting, safe and reliable hot air, with rapid temperature rise in the heated space (可控).
