How to Select a High Temperature Circulation Fan
To select a high temperature circulation fan, confirm airflow, pressure, normal and maximum temperature, gas medium, installation position, drive method, insulation requirement, material, and continuous operating condition. High temperature fan selection must consider thermal expansion and bearing protection.
Important Parameters
- Airflow
- Static or total pressure
- Normal operating temperature
- Maximum temperature
- Gas medium
- Installation inside or outside the oven
- Insulation structure
- Motor position
- Drive method
Material and Structure
Carbon steel may be suitable for some medium-temperature applications. Stainless steel or high-temperature steel may be required for higher temperatures or special process conditions. The impeller, shaft, bearing housing, casing, and thermal insulation should be designed together.
Drive Method
Belt drive can help keep the motor away from heat. Coupling drive is often used for heavier-duty systems. The final drive method depends on fan power, temperature, layout, and maintenance preference.
Zhichengfans Selection Support
Zhichengfans can support high temperature circulation fan selection for coating lines, galvanizing lines, drying ovens, curing ovens, food drying systems, and industrial hot air recirculation systems.
FAQ
Can a normal centrifugal fan be used for high temperature circulation?
Usually no. High temperature systems require suitable material, bearing protection, insulation, and thermal design.
What temperature information should be provided?
Provide normal operating temperature, maximum temperature, and whether the temperature is continuous or temporary.
