In the fluid dynamics laboratory of our Wasserburg competence centre, we design new fan wheels and turbines and optimise existing systems for performance, energy efficiency and noise emissions. We also develop complete systems of wheels with power units.

Our range of tests includes suction operation, pressure operation and also unpressurised measurements. Revolutions up to 40,000 r/min and diameters of up to 250mm are possible. In our prototype department, we are able to simulate or modify the environmental circumstances of the fan wheels or turbines, thus achieving optimal operational conditions. Furthermore, we carry out mould-flow analysis, use ANSYS from external partners for the flow simulation and establish the fault probability and fault effect with FPFEs.

Our on-site, tool-making workshop constructs tools for fan wheels with a diameter of 30-250mm, for complex slide tools as well as for wheels with welded discs/blades.

Fan wheel manufacture is carried out in both Wasserburg and in Michalovce/Slovakia.
The fan wheel hubs are manufactured according to the requirements of our customers out of materials such as stainless steel, zinc die-casting, sintering material or aluminium. Thanks to our long experience and our technological systems, we achieve excellent results relating to balance and both axial and radial run-out.
