»The warmest calm«


Air/water heat pumps are becoming an important pillar of more sustainable heat generation. This is where fans that work intelligently, quietly and economically at optimum efficiency come into play, as well as inverter electronics for the compressor drive that reduce operating noise through optimum commutation and also increase the energy efficiency of the heat pump.

»Soundcheck for heatpumps: Psychoacoustics for minimum noise generation«


Air/water heatpumps with heat outputs from 3 to 30 kW enjoy a high level of acceptance in heating technology. However, they do not work completely silently and the more dense the buildings are, the more the neighbors can get disturbed by noise pollution. It is by no means just the measurable sound pressure level that is crucial, but human noise perception, which is where psychoacoustics and its examination methods come into play.

»Reduce pressure losses, increase efficiency«


Everyone is looking for the perfect fan for their refrigeration and air conditioning applications. Simulation provides help with this: the behavior of a fan in the specific application can be precisely calculated and visualized with CFD (Computational Fluid Dynamics, i.e. numerical fluid mechanics).

»The right solution for every installation situation«


Fans are complex flow machines, which sometimes respond to aerodynamic changes in their surroundings. The installation situation plays an important role here. This means that, when installed in the application, the fan is often not as quiet as hoped for, or less efficient than promised in the data sheet. Last but not least, we recommend having the fan manufacturer on board at an early stage of in-house unit development. This means there will certainly be no unpleasant surprises later.
