Independent of the choice of controlling the fan, it will deliver excellent efficiency (>92% top efficiency).
Fully optimized fan selections
We design tools and design process ensures that the fan selection is fully optimized. This meaning full control of where the top efficiency is chosen in order to meet the by the customers requested design duty points. Fläkt Woods has many different design options to choose from enabling a fan selection that can be fully optimized on various parameters, such as flow, pressure, power (efficiency) or noise levels.
Precise and step less blade pitch control with low hysteresis
The blade pitch control system is hydraulic using a hydraulic cylinder to transfer the forces from the hydraulic pressure to create blade pitch movement. Our design is reliable and robust, delivering a fast response to any blade pitch change request. The system is controlled using a small control loop with a control card and a proportional valve, ensuring that the by the plant control system (DCS) required blade pitch is reached in a fast and controlled way.
Stringent quality control with no welds in rotating parts
The manufacturing process of the PF fans is controlled by a stringent quality control system to ensure high quality deliveries in time. In order to fully comply with customer fan specifications, we have a robust project management and design process, where all aspects of the fan design and customer requirements are covered. Every part is controlled before assembly and every rotor with variable pitch in motion is spin tested with the complete delivery unit. There are no welds in the rotor, meaning that there is no risk for cracks or any need to weld inspection on any rotating part.
