High-Temperature Centrifugal Forward Curve Fans-Image

High-Temperature Centrifugal Forward Curve Fans

Robinson FC fans are furnished with forward-curve wheels that are ideally suited for applications involving continuous operation at temperatures ranging from 70° F to 2,000° F. FC Series units are often constructed of special alloy materials for high-temperature service, but are used also for low-temperature operations. Other fan types designed and built by Robinson for high-temperature applications include axial flow, paddle wheel and radial blade series.

Performance Ratings

Robinson's FC design is a result of thorough and exacting laboratory testing. Documented performance ratings from this work enable Robinson to provide equipment for quiet, efficient service over a broad performance range.

Design Considerations

  • FC fans may be furnished with either non-insulated or fully insulated units.
  • FC fans are also offered with an insulated plug and non-insulated housing. In this type of construction, the non-insulated housing is usually mounted on the inside wall of the furnace or oven.
  • All Robinson FC Series are available in multiple fan arrangements. Flexibility in design also allows Robinson to offer both round and square plugs to accommodate a wide range of furnace requirements. Other capabilities include gas-tight designs.
  • For reliable, efficient service, Robinson has always stressed the importance of preventive maintenance. Fan casings are therefore designed with either plug-type housings or split housings for accessibility to the wheel for service and/or removal.

Quality Control

Dye penetrant testing, ultrasonic testing, vibration analysis, x-ray testing and, in some cases, magnetic particle inspection, are utilized to ensure that FC Series fans meet Robinson's stringent quality control requirements. Other steps taken to ensure long fan life include dynamic balancing of the wheel and shaft assembly on independent, computerized equipment. Full-scale mechanical testing is performed on the assembled FC unit (when possible) prior to shipment.

Fan Repair and Field Service

Robinson field service representatives are available for troubleshooting, field balancing and diagnostic inspection of fans and other types of rotating equipment. These personnel supervise certain on-site repairs or, if necessary, determine whether the unit must be factory-repaired.

Robinson repairs and rebuilds FC units as well as all types of industrial fans, regardless of original manufacturer. In addition to fan repair as a cost-saving alternative, Robinson redesigns and upgrades existing air-moving equipment to increase capacity and improve efficiency.
