HEALTH & SAFETY Considerations when specifying fans for surface treatment plant Specifying fans does not just boil down to matching an airflow and pressure requirement, there are several factors that need to be taken into account, not least of which are temperature rating, corrosion resistance, IP rating, available electrical supply, location and controllability. Sodeca’s expert staff discuss the application with their customers to evaluate the specifi c ventilation needs for their process plant, whether it be for spray booths, ovens, de-greasers or fume control. They can then specify the right fan from their vast range of products. For example, fans are often required to transport air at elevated temperatures, in which case, Sodeca can offer centrifugal fans as well as bifurcated and belt driven axials. Some types of axial fan with motors that are in the airstream can also be offered, depending on the temperature/humidity combination. Where corrosive atmospheres are a problem, fans can often be manufactured in polypropylene and 304 or 316 stainless steel, depending on the corrosive substance and its compatibility with the material of manufacture. Fans can also be made suitable for marine and coastal environments. 86 The durability of the fan motor can often be a big factor when selecting a fan model. Consideration needs to be given to the environment that the motors will be working in, giving particular thought to the ambient temperature, enclosure rating and atmosphere, making sure that the motor will give good performance in the location in which it will be running. The available electrical supply will influence whether or not the motor needs to be three phase or single phase and will influence what voltage and frequency it needs to operate at. Motor and fan control are also important when selecting the right fan for the job. The starters, speed controllers, frequency inverters and assorted sensors that Sodeca offer allow fans to be controlled in a number of ways. Fans are often required to transport hazardous (flammable) gases or dusts (or a combination of both) or the fan itself may be located in a hazardous area. As well as European ATEX certification, Sodeca’s fans can carry hazardous location certification for many other parts of the world, including CSA, IECEx, CUTR, SAA, NEPSI, TIIS and INMETRO. In short, if a customer’s process plant is being exported, it is unlikely that Sodeca will not be able to specify a fan suitable for use in the destination country. Sodeca staff have a wealth of experience when specifying the right fan for the job. They offer “solutions” rather than just “products” and are always pleased to discuss the customer’s needs in detail to make sure that they get the best ventilation products for their application. Once a product is selected, the customer will can see exactly what it is proposed from data sheets supplied or, in most cases, they will have 2d CAD drawings or 3d models available electronically. In addition, they can use the QuickFan selection software for further information and to use its calculation tools.
