The Air Duct Heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, and the maximum effective temperature is 500 ºC. It has been widely used in many scientific research and production laboratories such as aerospace, industry, chemical industry and universities. It is especially suitable for the test of automatic temperature control and large flow high temperature combined system and accessories. The electric air heater has a wide range of use: it can heat any gas. The generated hot air is dry, moisture-free, non-conductive, non-combustible, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space heats up quickly and the temperature can be controlled.Specification
