Ensure that your industrial fans work properly to improve your occupants’ comfort

Here are some practical tips on how to manage your industrial fans



The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) defines a fan as follows: “an air pump that creates a difference in pressure and causing air flow”. The turbine does most of the work, giving the air static and kinetic energy that varies depending on the type of fan. Fans are divided into two categories: helical (or axial) and centrifuges. Helical/axial fans make the air pass through parallel to the driveshaft. With centrifugal fans, the air takes a right angle from the entry to the exit.



Industrial fans can sometimes provide a temporary alternative to air conditioning. They can cool the occupants of a building by circulating or ventilating the air, thus accelerating the evaporation of perspiration. A fan replaces warm, stuffy indoor air with refreshing, new outside air. In many industrial applications, fan control presents a real opportunity for superior efficiency at reduced cost. A simple and inexpensive way is to add dampers, which add resistance and reduce flow while increasing pressure. This increased pressure causes an increase in energy consumption according to the required flow rate. Alternatives to flow control include reductions in fan speed through the use of belts and pulleys or variable speed regulator.

There are some other great methods.
