3D air electric heater

1. Application field:

Electric air heaters are mainly used to heat the required airflow from the initial temperature to the desired air temperature, with a maximum temperature of 850 ℃. Widely used in scientific research and production laboratories such as aerospace, weapons industry, chemical industry, and higher education institutions. Especially suitable for automatic temperature control, high flow and high temperature combined systems and accessory testing. The electric air heater has a wide range of applications: it can heat any gas, and the generated hot air is dry, non-conductive, non flammable, non explosive, non chemical corrosion, non polluting, safe and reliable. The temperature of the heated space is fast (controllable).

2. Technical features:

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

2. High efficiency: greater than 0.9.

3. Heating and cooling speed block, up to 10 ℃/s, with fast and stable adjustment. Temperature control does not drift due to the leading and lagging of controlled air temperature, making it very suitable for automatic control.

4. Good mechanical performance: Due to its heating element being made of special alloy materials, under the impact of high-pressure airflow, its mechanical performance and strength are superior to any heating element, and superior to the tests of systems and accessories that require long-term continuous heating of air.

5. It is durable and has a lifespan of up to ten years, provided that it does not violate usage regulations.

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

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

3. Specification and model

Single power range from 2kW to 10000kW
