Primary Industries for Tempering Air Fans
Many industries use tempered glass, including automotive, building materials, and furniture for safety so that it does not shatter even if broken. Similarly, industries that use tempered steel span across industries like automotive, aerospace, agriculture, energy & oil, hardware, and even industrial fans. Finally, virtually all industries that use boilers or calciners might also use tempered air fans. It’s very common in power plants and heavy-duty industrial manufacturing. All of these may require tempering air.
Air Tempering Fan Selection & Specification
The industrial forced draft fans (FD Fans) used in tempering typically require high volume and high horsepower. Efficiency is always a factor too, so we often bring in a backward curved model. In fact, in glass tempering, a series of two fans can help supply the necessary pressure and flow without maxing out the fan performance curve. But there are many options depending on your specific performance requirements.
Fan Designs Used in Tempering Applications
Fan Arrangements indicate how the motors mount to and drive the fan. For a tempering air fan, we typically use a direct drive arrangement, usually, Arrangement 4 or Arrangement 8, unless the blower is very large, in which case we might specify an Arrangement 7:
Arrangement 4 – Direct Drive with an overhung impeller. A low-cost arrangement, the fan wheel mounts directly on the motor shaft.
Arrangement 4V / Top Mount – Direct Drive with an overhung impeller. The wheel also mounts directly on the motor shaft, but in a vertical position.
Arrangement 7 – Direct Drive with a center-hung impeller. The motor is directly coupled to the fan shaft with a bearing on either side of the fan wheel. Involves a bearing on either side of the fan wheel and is supported by the fan housing.
Arrangement 8 – Direct Drive with an overhung impeller. The fan shaft is directly coupled to the motor shaft with a flexible coupling.
Accessories, & Design
Installed on the back end of the glass oven, calciner, metal tempering, or boiler system, these fans provide supply air for the tempering process. When it comes to design and accessories, it’s all about protecting and optimizing operations, maintenance, and life of the fan and bearings.
