Control the humidity in your greenhouse by bringing cold air from above the closed screen. Eliminate humidity related diseases such as botrytis with the screens closed.
You can use the room between the roof and screens as a climate chamber. This system will push the colder and dryer air into the glasshouse. Warmer and more humid air will be pushed up and will leave the glasshouse trough the screens.
The system is equipped with a RPM adjustable vertical distribution fan which ensures an optimum climate for your crop by creating uniform temperature, humidity and CO2. The capacity from both fans can be determined by the horticultural computer, which can be controlled per climate group.
