An air heater is an electric heating device primarily designed to heat gas flows. Below is a detailed explanation of it:

I. Working Principle

Operation Principle of Air Heater

For electrically heated air heaters, the heating element is a stainless steel heating tube, which is formed by inserting an electric heating wire into a seamless steel tube. After filling the gaps with magnesium oxide powder, which has good thermal conductivity and insulation, the tube is shrinked. When current passes through the high-temperature resistive wire, the heat generated diffuses to the surface of the heating tube through the crystalline magnesium oxide powder, and then transfers to the heated air to achieve the heating effect.

II. Technical Features

Air heaters can heat the air to very high temperatures, typically up to 450°C, with the housing temperature only around 50°C.

High heating efficiency, over 0.9.

Rapid heating and cooling rates up to 10℃/s, with quick and stable adjustment. Suitable for automatic control, it avoids the phenomenon of air temperature overshooting and lagging, ensuring stable temperature control.

Excellent mechanical properties due to its specially formulated alloy material for the heating element, which outperforms any heating element in terms of mechanical properties and strength under the impact of high-pressure air flow. This is particularly advantageous for systems and accessories that require continuous and uninterrupted air heating over extended periods.

Durable and long-lasting, with a lifespan of several decades when used according to instructions.

Clean air, compact size.
