The Hoval Muonio sorption rotor transfers humidity to the maximum extent possible. For this purpose, its surfaces are coated with a highly effective 3 Å molecular sieve. The humidity is transferred through adsorption and desorption exclusively. The high humidity transmission ...



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 ...
