Air Heater
Darry Electric recommends
Air Heater is an electric heating device mainly used to heat gas flow. The heating element of the air heater is a stainless steel electric heating tube. The inner cavity of the heater is equipped with multiple baffles (guide plates) to guide the gas flow, prolong the residence time of the gas in the cavity, thereby fully heating the gas, making the gas heating uniform, and improving heat exchange efficiency. The heating element of the air heater, the stainless steel heating tube, is made by inserting electric heating wires into a seamless steel tube, filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, and then shrinking the tube. When current passes through the high-temperature resistance wire, the generated heat diffuses through the crystalline magnesium oxide powder to the surface of the heating tube, and then is transferred to the heated air to achieve the purpose of heating.
Equipment Introduction
The air heater is an electric heating device that uses heating tubes installed in a cylindrical insulation container to heat gas.
The air heater has the characteristics of fast heating speed, good insulation performance, and high heating temperature.
The air heater is usually used to heat air, nitrogen, and other gases, and can heat the gas to the required temperature in a very short time.
Specific dimensions and heating time are customized according to customer requirements.
I. Application Fields:
The air heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 600°C. It has been widely used in many scientific research laboratories such as aerospace, weapon industry, chemical industry, and higher education institutions. It is especially suitable for automatic temperature control and high-flow high-temperature combined systems and accessory tests. The air heater has a wide range of applications: it can heat any gas, producing hot air that is dry, non-conductive, non-flammable, non-explosive, non-corrosive, non-polluting, safe and reliable, and the heated space heats up quickly (controllable).
II. Technical Features
1. It can heat air to a very high temperature, up to 600°C, while the shell temperature is only about 50°C.
2. High efficiency: up to 98% or more.
3. Fast heating and cooling rates, up to 10°C/s, with fast and stable adjustment. There will be no leading or lagging of the controlled air temperature, causing temperature control drift, making it very suitable for automatic control.
4. Good mechanical performance: because its heating element is made of special alloy material, under the impact of high-pressure air flow, its mechanical performance and strength are better than any other heating element, which is more advantageous for systems and accessory tests that require continuous air heating for a long time.
5. When used in accordance with operating procedures, it is durable and has a service life of up to decades.
6. Clean air and small size.
7. Multiple types of air electric heaters can be designed according to user needs.
