High Temperature Fans
Industrial processes often require high heat fans that can withstand operating airstream temperatures up to and above 2,000 degrees Fahrenheit. These high-temperature industrial fans depending upon temperature requirements are available insulated and uninsulated in both axial and centrifugal designs. Custom designs and configurations are the norms with many features including air-cooled shafts up to 1,850 degrees Fahrenheit with no need for water cooling. Oftentimes they are part of an OEM package where space is a premium. We’ve applied high-temperature fans and blowers for re-circulating air in high-temperature equipment, exhausting gases and fumes, and supplying air for heating and drying systems.
High-Temperature Wheels/Propellers
Wheels or impellers are defined by the blade configuration. Blade configuration is adjusted based on temperature, performance requirements, and materials in the airstream.
- Backward Inclined – Flat fan blades tilt backward from the center of the wheel
- Forward Curved – Fan blades are curved and tilt forward
- Open Paddle Wheel – Flat blades that radiate from the center of the fan wheel
- Axial – Propeller bladed fan wheels
High-Temperature Fan Construction Options
SysTech is able to provide both standard high-temperature fans from stock and custom fan designs for many high-temperature processes.
Standard Carbon Steel Fan Construction:
- to 300° F. (149° C.) Available in Arrangements 1, 8, 9, 9CB and 10
- to 200° F. (93° C.) Available in Arrangements 4and 4HM
High-temperature fan construction based on airstream temperature:
- 201°- 400° F. (94° – 204° C.) Uses standard fan with heat slinger, slinger guard, Teflon shaft seal, and extended hub on wheel. Arrangements 4 and 4HM only.
- 301°- 400° F. (150° – 204° C.) Uses standard fan with heat slinger, fan shaft and slinger guard, and Teflon shaft seal. Arrangements 1, 8, 9, and 9CB.
- 401°- 600° F. (205° – 316° C.) Uses standard fan with heat slinger, fan shaft and slinger guard, high temp shaft seal, gaskets, and paint. Arrangements 1, 8, 9, and 9CB.
- 601°- 750° F. (317° – 398° C.) Uses standard fan with high temp bearings, heat slinger, fan shaft and slinger guard, high temp shaft seal, gaskets, and paint. Arrangements 1, 8, 9, and 9CB.
- 801°- 2200° F. (413° – 1200° C.) Materials of construction change as required (higher yield strength steels) to meet requirements of high-temperature processes.
High heat fan configurations may also include:
- Plug fan designs with three, six or eight-inch insulated boxes
- Completely insulated housings for free-standing fans, with three, six, eight or more inches of housing insulation
- Gas-tight construction
- High-temperature shaft
- Reversible axial flow units
- High-Temperature hub
- Copper extended lube lines
- High-temperature door gaskets
- Air-cooled shaft and bearings
