The electric air heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850 ° C. Has been widely used in aerospace, meltblown nonwovens, films, chemical industry and universities and many other scientific research and production laboratories. The air heater must resist the oxidation of high-temperature air, so the material must be stainless steel. The heating element of the air heater is a stainless steel electric heating tube. Multiple baffles are installed in the heater cavity to extend the residence time of air in the heater cavity to improve the heat exchange efficiency. Properly increasing the number of heating pipes and increasing the installed power of air heaters can shorten the startup temperature of the production line. The air electric heater has a wide range of use: it can heat any gas, and the hot air produced will be dry without moisture, non-conductive, non-flammable, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space will heat up quickly Controllable).
1. The pipe heater can heat the air to a very high temperature, up to 850 ° C, and the shell temperature is only about 50 ° C.
2. High efficiency of gas heater : more than 90%.
3. The heating and cooling rate of the pipeline heater can reach 10 ℃ / S, and the adjustment is fast and stable. The temperature of the controlled air does not appear to lead and lag, which makes the temperature control drift, which is very suitable for automatic control.
4. The mechanical performance of the pipeline heater is good: because its heating element is a special alloy material, it is better than any heating element in terms of mechanical properties and strength under the impact of high-pressure air flow. The heating system and accessory tests are even more superior.
5. Pipeline heaters are durable and have a service life of up to ten years without violating the usage regulations.
6. The pipeline heater has clean air and small volume.
7. Pipe heaters can be designed with various types of electric air heaters according to the needs of users. Specifications of single power from 2KW to 10000KW series.
