Atmospheric humidity in a greenhouse is a key growing factor because it influences the production and quality of the crops, directly and indirectly. A high pressure air humidification system, also known as a fogging or misting system, is used to control the relative humidity or to cool the air.
The misting system can be used to create a cooling effect. Depending on the outside air temperature, a temperature reduction of more than 8 degrees can be achieved compared to sections without cooling. It is also possible to maintain a single growing section at temperature with this system.
The operating pressure of the high pressure misting system is between 70 and 120 bar. This tremendous pressure creates a very fine mist. The uniform microscopic misting is so fine that it immediately evaporates and does not settle on the crops.
