Nonwoven Fabric Heater Manufacturer RecommendationCompressed air heater is an electric heating device mainly used to heat gas flow. The inner cavity of the compressed air heater is equipped with multiple baffles (guide plates) to guide the gas flow direction, prolong the residence time of gas in the inner cavity, thereby fully heating the gas, making the gas heating uniform, and improving heat exchange efficiency. The heating element of the compressed air heater is a stainless steel heating tube, which is made by inserting electric heating wire into a seamless steel tube, filling the gap with magnesium oxide powder with good thermal conductivity and insulation, and then shrinking the tube. When current passes through the high-temperature resistance wire, the generated heat is diffused to the surface of the heating tube through crystalline magnesium oxide powder, and then transferred to the heated gas to achieve the purpose of heating.
Scope of application:
Compressed air heater is a widely used type of heater. We commonly call it compressed air heater. In fact, it can be subdivided into many types according to the different heating air, and these can all be called duct-type compressed air heaters. The control part of the electric heater is a precision instrument. It should be handled with care during transportation, and impact and collision are strictly prohibited. The cylinder part should be hoisted reasonably to avoid deformation and damage to internal heating elements. The compressed air heater and control cabinet should be placed in the warehouse, and rain is strictly prohibited.
Working principle of compressed air heater:
High-temperature resistance wires are evenly distributed in the high-temperature resistant stainless steel seamless tube, and the gaps are densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced and has high thermal efficiency, but also has uniform heating. When current passes through the high-temperature resistance wire, the generated heat is diffused to the surface of the metal tube through crystalline magnesium oxide powder, and then transferred to the heated part or air gas to achieve the purpose of heating.
Compressed air heater is mainly used to heat the required gas flow from the initial temperature to the required gas temperature, up to 800°C. It has been widely used in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry, and universities. It is particularly suitable for automatic temperature control and large flow high-temperature combined systems and accessory tests. The compressed air heater has a wide range of use: it can heat any gas, and the generated hot gas is dry and moisture-free, non-conductive, non-combustible, non-explosive, non-corrosive, reliable, and the heated space heats up quickly (controllable).
Technical characteristics of compressed air heater:Nonwoven Fabric Heater Manufacturer Recommendation
1. Fast heating and cooling rates, up to 10°C/s, with fast and stable adjustment. There will be no leading or lagging phenomenon of the controlled gas temperature causing temperature control drift, which is very suitable for automatic control.
2. High efficiency: up to 0.95 or above.
3. Good mechanical performance: Because its heating element is made of alloy material, under the impact of high-pressure gas 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 heating of gas for a long time.
4. It can heat the gas to a very high temperature, up to 800°C, while the shell temperature is only about 50°C.
5. When used in accordance with operating procedures, it is durable and has a service life of up to several decades.
6. Clean gas and small volume.
7. According to user needs, multiple types of air electric heaters can be designed.
8. Outlet temperature and flow rate are controllable, with variable frequency speed regulation.
9. Single unit power ranges from 2KW to 2000KW series.
