Centrifugal fans can be considered the heart of many industrial processing industries. Industrial centrifugal fans can be customized for excellence in the performance of the fan. The industrial centrifugal fans are custom built based on specific needs of the industry and designed keeping in mind cost, reliability, efficiency, and process parameters. The designs of custom fans emerged after intensive theoretical calculations, simulation using various software packages, and rigorous testing for performance. The fast-growing power, chemical, steel, cement industries and technology that has brought about plant sizes that are much larger than what they used to behave made it to develop custom-built industrial fans that are powerful and can withstand high temperatures and extreme wear. The performance tests are carried out on the custom fans to maintain measurement errors as low as possible. Some of the applications of custom-built industrial centrifugal fans are boilers, chemical, and cement plants, paper manufacturing plants, iron & steel plants, ore processing plants, incineration plants, ventilation of industries, and ventilation of commercial complexes and tunnels. Customizing industrial centrifugal fans will give you the benefit to enjoy the flexibility of choosing any combination of the numerous accessories based on the required levels of efficiency, reliability, convenience, cost, and sophistication. Some of the various options of accessories are grid coupling, pin & bush type flexible coupling, square dampers for flow control, circular dampers for flow control, inlet guide vanes for flow control, silencers placed at the blower inlet, mechanical actuators for dampers, pneumatic actuators for dampers, etc. Grid couplings are more resilient and reliable, they are generally used for heavy-duty applications where reliability is important although they may not be economically the best option. Dampers can also be custom-built based on flow and pressure conditions. Inlet guide vanes tend to offer higher efficiency compared to square and circular dampers, they are used for applications in which clean air is circulated. Dampers can be placed in the ducting of the fan for the control of flow. Silencers are used for eliminating noise to ensure that the noise levels in the shop floor are well within the accepted limits, they are generally open to the atmosphere. Actuators are used for opening or closing of dampers, if the compressed air supply is readily available the pneumatic actuators are more cost-effective than mechanical actuators. Bearings are one of the most critical parts of an industrial centrifugal fan, they can cause mechanical problems if the proper selection is not made. There are some options in bearings to choose from for using them in custom-built fans. Self-aligning bearings or spherical roller bearings can tolerate misalignment and are reliable and cheap compared to other options. When thrust load, temperature, and dynamic forces are high, a combination of deep groove ball bearings and cylindrical roller bearings in a tabular housing can be used. Also, you can choose from different options of instrumentation for fans. Instead of spending time searching for industrial centrifugal fans that are a perfect fit, you can customize the fan to suit specific needs. The custom-built fan can come up with many benefits like budget flexibility, energy saving, a variety of options, maximize functionality, high reliability, quality of parts, right materials and increase in overall performance and efficiency of fans.
