Electric air heater is a kind of widely used heater. We call it an electric air heater. In fact, according to the different heating gas, it can be divided into many kinds. Common are nitrogen electric heater and hydrogen electric heater, also known as pipeline gas heater. Electric air heater is especially suitable for automatic temperature control and high temperature combined system with large flow rate and accessories test.

The electric air heater used for heating a wide range of air can be any gas, which can be heated by drying hot air without moisture, non conductivity, non combustion, non explosive, non chemical corrosion, pollution-free, safe and reliable, and can be heated in a fast heating space. The air in the air heater is a cylindrical heat preservation container which is installed in an electric heating device to heat the gas in the heating pipe. Air heater has fast heating rate, good insulation performance and high temperature heating. For general air heating, such as nitrogen air electric heater, the gas can be heated to the required temperature in a short time. Air heater in alternating magnetic field of eddy current heat itself, is usually used in metal heat treatment.

The air heater is a thick metal that is in principle an alternating magnetic field that generates current due to electromagnetic induction. After the current generated by thick metal, the current flow path formed in the metal spiral makes the heat generated by the current absorbed in the metal itself, which will lead to the rapid temperature rise of the metal. The air heater can heat the air at very high temperatures up to 450 ℃, and the shell temperature is only about 50 ℃. The heating and cooling rate of air heater block is as high as 10 ℃ / s, which can be adjusted quickly and stably.

It will not lead to the phenomenon that the controlled air environment temperature is ahead of time and lag, and the working temperature can be controlled to drift indefinitely, which is very suitable for students' automatic management and control. Because its heater is made of special alloy material, it has better mechanical performance and strength than any other heating element under the impact of high-pressure air flow, which is more superior to the test results of the system and accessories for which we need to continuously develop air heating for a long time. When it does not violate the national technical regulations, it is durable and can be used for decades. When the characteristic information such as temperature, performance and efficiency is of great theoretical significance, it is helpful for the buyer to select the appropriate heater suitable for the application.
