• low energy consumption: just 4 W/(kg/h), equal to 1150 W for the 250 kg/h model;
• high capacity: standard models are available with capacities from 60 kg/h to 500 kg/h, and custom models up to 5000 kg/h;
• very fine atomisation that requires minimum space for evaporation);
• wide range of models for all requirements:
- with inverter: can be configured to
humidify in the AHU/duct or to supply water at a constant pressure, with high precision (multi-point applications);
- without inverter: the capacity is
modulated in steps, while the water pressure is fixed (70 bar): this mode is used for direct humidification in the room or multiple zones;
• adiabatic cooling: humidifies and the cools the air (even up to 10 °C);
• hygiene: in the AHU/duct applications humiFog is certified according to the most recent European standards (VDI6022); for
ambient humidification the water distribution lines downstream of the pump can be automatically emptied and washed.

Characteristics of the supply water

For correct operation, the humiFog system should be supplied with treated water that has the characteristics described on the following pages. To reach these values, in normal circumstances a reverse osmosis system is required for the treatment of mains water. The principle that the operation of this system is based on involves sending the water through a special membrane that is only permeable to molecules that are the same size as H2O, thus removing most of the mineral salts present. These systems have with outputs that range from a few litres to several cubic metres of water per hour, and can therefore be used to supply a series of humiFog appliances. When the water characteristics are correct, the risks of blocking the nozzles and conveying dust into the environment are reduced significantly. On the other hand, using tap water that can contain up to 500 mg/l of dissolved salts, in one year up to 100 kg of very fine mineral dust (small solid particles from 0.5 to 1 µm in diameter) will be deposited and may block the atomising nozzles.
