The need to make the invisible measurable created Produal. We wanted to give buildings the ability to sense. We invented devices to measure and manage the changing indoor circumstances of the buildings. The demand to optimise the building ecosystem and to minimise costs and the environmental impact guides us. Our experts develop solutions that measure, adjust and communicate accurate data for the building automation and HVAC industry. Together, we make the invisible visible and give extra years to buildings’ life cycle – doing our share of building a sustainable world.
