Zehnder Group is one of the global market leaders in the development, production and marketing of radiators and ventilation systems. They basically provide everything one can need for a comfortable and healthy indoor climate.

For most of Zehnder’s products the design targets are similar: less energy usage, less noise, and no visible pollution. In the past few years, Actiflow was involved in the design of different ventilation valves, fans and louvres. In our most recent project for Zehnder, Actiflow designed a new fan housing creating significantly less noise than the previous version of the housing.
