Noctis Thermo - Fachjan Project Plants
"With Noctis Thermo, we are reaching an extra 10% of energy savings".
Fachjan cultivates a wide range of green plants for day trading, interior, and project planting. Fachjan has 10 hectares of greenhouses spread over four locations. At the location in ‘s-Gravenzande, Phormium spoke with Ron van der Knaap. As one of the first, Fachjan replaced the top screen here in 2023 with the innovative Noctis Thermo.
In ‘s-Gravenzande, cultivation is done with SON-T lamps and a daily temperature of 20°C. Additionally, the PAR light quantity is controlled by means of a variable shading system, which benefits the growth of the plants. The facilities in the greenhouse, including the screens, are adapted to this cultivation strategy.
The high average day temperature leads to a demand for energy savings. The lighting regime requires a solution for light emissions and controlling the PAR light quantity in the greenhouse calls for a - preferably variable – screening system. Noctis Thermo meets all three of these requirements.
There were several options considered for energy savings at Fachjan, but this is the most suitable. “The extra energy savings we achieve with Noctis Thermo are noticeable,” says Ron. “The minimum pipe temperature can be 5 degrees lower with the screen, which corresponds to about 10% of energy savings,” he explains.
Ron further explains, “I mainly use Noctis Thermo to save energy, but also as a night screen in the sense of a light restriction screen. We illuminate at night and early in the morning. Regardless of the lighting, the Noctis Thermo screen is always closed at night.”
At higher radiation levels the screen is also used for variable shading in combination with the diffuse screen. At Fachjan, Noctis Thermo, which shades 99%, is used to adjust the amount of incoming light to the needs of the crop.
