Nivola presents a new solution for climate control under 100% closed screens in existing and new greenhouses.
The need for light shielding by growers is continuously increasing. Last Monday, Hortidaily posted:
‘’Passed on December 8th, 2020 by the municipality of Leamington, the “Greenhouse Light Abatement Bylaw” was enacted in an effort to curb light pollution by the region’s numerous greenhouse operations’’.
Closed climate screens are demanded more and more by laws and regulations. Growers are forced to oblige and risk a detrimental growing climate.
Not all is lost, though. Growers can use this necessity to obtain great benefits such as greater energy savings and to solve temperature differences.
As you may know, when you close the screens several problems will arise. Not only will there be less air movement, leading to a dead climate, but also the temperature and humidity will rise.
Optimizing the climate with 100% closed screens therefore requires a different approach.
"A simple system that is easy to install in existing and new greenhouses. The Nivolution brings dry and cool air in the greenhouse from above the screens. This allows you to maintain the desired climate and control humidity levels with closed screens!", Nivola is proud to announce.
The Nivolution systems works with two components: the Nivolution transportation fan for transporting air through the screens and the Nivolator® vertical fan for air circulation in the greenhouse. The benefits of this system are amongst others dehumidification to obtain the desired humidity under 100% closed screens, and the creation of a homogeneous temperature and CO2 distribution both vertically as well as horizontally in the greenhouse.
This will bring activity in the crop, as the greenhouse will probably cool down. This, in turn, might save up to 50% on energy usage.
With the Nivolution greenhouses can dehumidify an average of 50 gr/m²/h (510 Liters/ha/h) in a controlled manner. The Nivolution can even be used for cooling, which is required for crops such as gerberas.
