The company RENSON is already more than 100 years old and originally was an aluminum production factory. In the last decade, Renson has shifted more and more from a production facility to a knowledge company. Their fields of expertise are ventilation, sun shading, screens, architectural constructions and building environmental applications. Today, RENSON VENTILATION NV is still the main business unit and specializes in ventilation of environmental buildings and houses. They focus mainly on natural ventilation, but for 5 years they have also produced products for mechanical ventilation. Especially in the sector of mechanical ventilation they intend to introduce a new product line which will communicate with KNX, especially KNX-RF. This will be the first KNX application Renson will develop, but other opportunities may follow.
