The universal WetUp 2.8 duct humidifier is fully automatic, energy-efficient, silent, and safe. It is a device that increases the relative humidity of the supply air as water evaporates.
Maintaining optimal indoor humidity at 40–60% improves comfort and overall well-being for the occupants. The WetUp 2.8 humidifier operates completely independently of the ventilation unit and can be used with any mechanical ventilation system, including already existing installations.
The built-in modulated PTC electric heater ensures that the air temperature remains at a comfortable level. The humidifier is connected directly to the mains water supply.
