Thanks to our know-how for the technically correct use of all types of fans, we can reduce your operating costs. The optimal design of the construction form, the size and the perfect planning lead to your ideal plant!
The variant of throttling with throttle valve or throttle louver is the simplest, but also the most lossy type. If the throttle is closed, the resistance increases. At the same time, the pressure loss becomes greater and the plantis shifted. The power curve of the fan remains unchanged.
Throttling is replaced by speed control. The advantages of controlled speed are obvious. Only exactly as much pressure increase is introduced into the respective operating point as the system requires in terms of resistance to enforce the required volume flow.
This is made possible by the generated pre-swirl via the adjustment of the guide vanes. The plantand the power curve of the fan change depending on the pitch angle of the guide vanes. On average, the additional investment costs are recouped within two years as a result of this design.
