Air pipeline heater nitrogen

Air pipeline heater nitrogen

Uniformly distribute high-temperature resistance wires inside the seamless stainless steel tube, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. This structure is not only advanced and has high thermal efficiency, but also generates uniform heat. When current passes through the high-temperature resistance wire, the heat generated diffuses to the surface of the metal tube through the crystalline magnesium oxide powder, and is then transferred to the heated element or air, achieving the purpose of heating.

Air electric heaters are mainly used to heat the required air flow from the initial temperature to the desired air temperature, up to 850 ℃.

Technical characteristics:

1. It can heat the air to a very high temperature, up to 850 ℃, while the shell temperature is only around 50 ℃.

2. High efficiency: up to 0.9 or above.

3. The heating and cooling rate block can reach 10 ℃/S, with fast and stable adjustment. It will not cause temperature control drift due to the phenomenon of controlled air temperature leading or lagging, making it very suitable for automatic control.

4. Good mechanical performance: Because its heating element is made of specially made alloy material, it has better mechanical performance and strength than any heating element under the impact of high-pressure air flow, which is more reliable for systems and accessory tests that require long-term continuous air heating.

5. Durable and long-lasting for up to ten years without violating usage regulations.

6. The air is clean and the volume is small.

7. Multiple types of air electric heaters can be designed according to user needs.

Single unit power range from 2KW to 10000KW series

Product Introduction:

It is mainly used to heat the required air flow from the initial temperature to the desired air temperature, up to a maximum of 850 ℃. It has been widely applied in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry, and higher education institutions. Especially suitable for automatic temperature control and high flow high-temperature combined systems and accessory testing. Air electric heaters have a wide range of applications: they can heat any gas, producing hot air that is dry, moisture free, non-conductive, non combustible, non explosive, non corrosive, non polluting, safe and reliable, and heats up the heated space quickly (controllable).

According to different heat sources and heating methods, it can be divided into electric heaters and direct fired air heaters.

Working Principle:

Install a primary coil with more turns and a secondary coil with fewer turns on the same iron core. The ratio of input to output voltage is equal to the ratio of coil turns, while the energy remains constant. Therefore, the secondary coil generates a large current under low voltage conditions. For induction heaters, the bearing is a short-circuit single turn secondary coil that generates a large amount of heat by passing a high current under low AC voltage conditions. The heater itself and the magnetic yoke are kept at room temperature. Due to the induction of current by this heating method, the bearing will be magnetized. It is important to ensure that the bearings are demagnetized in the future so that they do not attract metal magnetic chips during operation. FAG induction heaters have automatic demagnetization function.

It is the use of metal to generate eddy currents in an alternating magnetic field to generate heat, usually used in metal heat treatment and other fields. The principle is that when thicker metals are in an alternating magnetic field, they will generate current due to electromagnetic induction. Thicker metals generate current, which forms a spiral flow path inside the metal. As a result, the heat generated by the current flow is absorbed by the metal itself, causing it to quickly heat up.
