Products Description

Air Heater
An air heater is an electric heating device that primarily heats a gas stream. The heating element of the air heater is a stainless steel electric heating tube, and the heater inner cavity is provided with a plurality of baffles to guide the gas flow direction, prolonging the residence time of the gas in the inner cavity, so that make the gas even heating to improve heat exchange efficiency.

Pipe air heater has been widely used in many research and production laboratories such as aerospace, weapons industry, chemical industry, melt-blown non woven industry and higher education institutions. Particularly suitable for automatic temperature control and large flow high temperature combined system and accessory test.
