Hoval energy recovery systems are independently tested time and time again (for example, at the building technology testing laboratory of the University of Lucerne). All technical data is based on these measurements. This means that this is reliable data for planners, installers and operators.
You can rely on certified performance data, particularly high leak-tightness and ultimate hygiene. As a founding member of the Eurovent certification programme for plate heat exchangers, we vouch for the reliability of the data and we put our name to it.
