ValkTrussRail | Standard ventilation capacity

‘Next Generation Growing’ has meanwhile become part of many a grower’s cultivation strategy. It stands for optimising production while reducing energy consumption.

The key elements of it are the following:

  • Moisture control under the screen
  • More frequent and longer use of screen cloths
  • Better handle on CO2 thanks to less natural ventilation 

Ventilation accuracy is crucial for Next Generation Growing. Van der Valk Horti Systems’ ValkTrussRail ventilation mechanism prevents ventilation windows from misaligning and not closing properly and ensures extremely uniform ventilation openings, making it the ideal solution for climate security for a greenhouse’s entire service life.

Calculations

The ValkTrussRail ventilation mechanism is calculated completely for each situation using the unique WinTop calculation program, which was developed in partnership with TNO, the Netherlands Organisation for Applied Scientific Research.

Based on various variables (the geometry of the roof, the maximum local wind load, the required opening angle, etc.), all factors that may affect the system’s reliability are calculated. Such factors include the required structural strength, clearance between the mechanism and the roof structure, and the position of the rail consoles and rack and pinions.
