High Temperature Centrifugal Blower

The High Temperature Centrifugal Blower we manufacture is special air supply equipment engineered for medium and high-temperature industrial process scenarios, dedicated to providing stable power for high-temperature gas transportation and hot air circulation ranging from 200℃ to 500℃. Drawing on 30 years of R&D and manufacturing experience for high-temperature fans, we directly address industry pain points of thermal deformation, bearing failure and structural strength attenuation of ordinary fans under high-temperature environments, developing this stable, long-service-life high-temperature centrifugal blower through three core technologies: heat-resistant material selection, thermal expansion compensation design and bearing cooling systems.

The High Temperature Centrifugal Blower is widely applied in core industrial processes including drying, heat treatment and waste heat recovery, serving as critical power equipment guaranteeing stable high-temperature process operation. The structural design of this high-temperature centrifugal blower fully adapts to high-temperature operation demands. The impeller is precision welded from premium heat-resistant alloy steel and undergoes stress relief heat treatment to maintain stable structural dimensions without deformation under sustained high-temperature environments. Reinforcing rib structures are installed on outer casing surfaces, with thermal insulation layers installable inside to control thermal deformation magnitude and reduce heat loss for lower process energy consumption.

The bearing box adopts an independent water-cooled or air-cooled cooling system paired with heat insulation section design to effectively block heat conduction to the transmission end and ensure bearings operate within safe temperature ranges at all times. Spindles reserve thermal expansion allowance with dedicated expansion structures to absorb axial elongation under high temperatures and prevent component stress damage. Meanwhile, we can customize material schemes including stainless steel and special alloy steel according to process gas composition and corrosive characteristics to adapt to unique high-temperature working conditions across different industries.

• Hot air circulation for drying processes: Supply high-temperature hot air circulation power for tunnel kilns and drying production lines in food, building materials and chemical industries to guarantee uniform material drying.
• Hot air circulation for heat treatment: Support metal heat treatment furnaces to realize forced circulation of high-temperature protective atmosphere inside furnaces and improve consistency of workpiece heat treatment quality.
• Waste heat recovery transportation: Used in various industrial waste heat recovery systems to transport high-temperature flue gas and hot air for stepped and efficient waste heat recovery.
• High-temperature process exhaust: Extract high-temperature waste gas generated by kilns and reaction equipment for stable transportation to subsequent purification and waste heat treatment processes.

As an original manufacturer with over 30 years of deep engagement in the industrial fan industry, we possess profound technical accumulation and R&D capabilities in high-temperature fans, establishing a dedicated high-temperature fan R&D team that collaborates with domestic scientific research universities to conduct technical research on high-temperature materials and thermal structure design. We hold 3 related patented technologies, among which protective cooling air conditioning device patents are fully applied in the cooling system of the High Temperature Centrifugal Blower, drastically boosting equipment high-temperature tolerance and service life.
