Technology and design
The technology is principally designed to be fully automatic. Dust, germs, algae, limescale, etc. are removed using suitable filters and biocides. For a single water wall, the technology is installed in the water wall basin. Where several water walls are implemented, all technical elements are housed in a separate technical room or technical tank.
The cooling water is circulated. (Depending on the rates of evaporation and condensation, fresh water inflow or outflow will be needed).

Requirements of the air conditioning system
- Reduction of particles, contaminants and odours
- Avoidance of draughts and asymmetries in the radiation of heat
- Germs live longer when the air is very dry
- Excess humidity promotes the growth of mould and mites
Operating principle: cooling/dehumidification
With cooled water, effective cooling and dehumidification of the ambient air is achieved.
Without water cooling, the ambient air is humidified to act against the dryness experienced indoors in winter.
Climate fountain – heat transfer processes
Climate fountain’s mode of action
Water circulates over a vertical panel in the room, forming an even film of liquid across the surface. Without cooling, the water evaporates and humidifies the ambient air. In the winter months, this can markedly improve comfort in dry rooms. In summer, on the other hand, a cooling unit is used to bring the temperature of the water below 10°C. Effective cooling and simultaneous dehumidification of the ambient air is thus achieved through the great difference between air and water temperatures. If the temperature of the water film is below the dew point temperature of the ambient air, the humidity in the air condenses on the water film and is drained away into the collection basin. Excess water flows away via an overflow and can be collected as needed for further use.
