Corroventa's journey

The first product that was launched had a major impact on the market as it was simple, user friendly and had a unique patented drying process that significantly shortened the drying time of a water damage. Corroventa’s founder Knut Claesson established an early collaboration with customers around Europe, which later also actively influenced the development of Corroventa’s products.

Our driving force has always been to find smart and effective solutions to facilitate the customer’s everyday life and through close dialogue, we create products that can withstand the toughest environments and last for many years. We aim to offer flexible products that work for all kinds of drying assignments and the latest in the market is the small but effective adsorption dehumidifier A1.
