The frequency converters are used to change the operating point of a fan in a efficient manner by regulating its turning speed.
The use of variable frequency drives means great energy savings in the long run since, apart from enabling start-up the fan without the shock due the inherent intensity peak, a more flexible operation can be achieved with the possibility of running the fan at any speed that is below the design speed.
In the last years the cost of this kind of equipment has greatly decreased and therefore they are being more and more used in many fan instalations due to the energy savings entailed.
We give advice on when and how this equipment is appropriate and can supply variable frequency drives from the most important manufacturers. In this way the client receives all the necessary equipment in one single supply.
