Pipe Heater

In-lineAir Heater(Electric Air Heater) /Pipe Air Heater

It heats the required air flow from the initial temperature to the desired air temperature, up to 850°C. It has been widely used in many scientific research and production laboratories such as aerospace, meltblown nonwovens, film, chemical industry, and universities. The air heater must resist oxidation from high-temperature air, so the material is stainless steel. The heating element of the air heater is a stainless steel electric heating tube. Multiple baffles are set in the inner cavity of the heater to prolong the residence time of air in the inner cavity, thereby improving heat exchange efficiency. Appropriately increasing the number of heating tubes and increasing the installed power of the air heater can shorten the start-up heating time of the production line.

Working Principle

● A digital temperature regulator, solid-state relay, and temperature measuring element form the measurement, regulation, and control loop. During the electric heating process, the temperature measuring element sends the electrical signal of the waterpipe electric heater outlet temperature to the digital temperature regulator for amplification. After comparison, the measured temperature value is displayed, and a signal is output to the input terminal of the solid-state relay, thereby controlling the heater, giving the control cabinet good control accuracy and regulation characteristics.

● The interlock device can be used to start and shut down the pipe electric heater remotely.
