Volute High-pressure High-temperature Fan

The Volute High-Pressure High-Temperature Fan is engineered as a robust workhorse capable of withstanding the dual challenges of extreme pressure (total pressure >15 kPa) and intense heat (>300°C). This rugged centrifugal fan is the definitive solution for the most demanding applications, including primary and secondary air systems in circulating fluidized bed (CFB) boilers, high-end chemical fluidized bed reactors, and special material sintering furnaces. Designed to standards such as ASME Section VIII, the product is built for reliability when failure is not an option.

Our core advantage lies in the innovative double-layer volute casing design. The inner layer, in contact with hot gases, is constructed from high-strength, heat-resistant plates such as AISI 310S or 12Cr1MoV for pressure containment. An outer structural shell of Q355B steel provides reinforcement, with an air gap or insulation between layers to control casing temperature and minimize thermal distortion. The impeller is crafted from advanced heat-resistant alloy steel, with welded units undergoing full stress relief and non-destructive testing (NDT). A powerful forced-circulation oil lubrication system with a heat exchanger maintains bearing temperatures below 70°C. The dedicated high-temperature, high-voltage motor (H-class insulation, IP55) is mounted on a reinforced base to absorb substantial reaction forces, making every Volute High-Pressure High-Temperature Fan a paragon of heavy-duty engineering.

Built to deliver consistent power under severe thermal and mechanical stress, the Volute High-Pressure High-Temperature Fan sets the benchmark for critical processes. Its performance parameters, detailed below, are tailored for industrial-scale operations requiring unwavering reliability.
