StabiMaxTwin | Ventilation mechanism
The StabiMaxTwin rail system has a unique construction, with the pullpush tubes (for individual control of the two air vent sections) installed on top of each other on the truss. This allows the two sets of push rods (from the uppermost and lowermost pull-push tube, resp.) to move through each other, and the screen can sit freely against the truss.
The StabiMaxTwin system consists of a hinge element with an exceptional form that keeps the push rods together in a steel grip. And it has a unique tube clip that, given its wide design, can absorb the tolerances of your greenhouse without difficulty and is absolutely free of torsion. The Valk-Plus push rods are customised exactly to your specifications in a completely automated production process. They undergo various unique processing steps to become distinctive in terms of functionality and ease of mounting.

Sustainable
For the required stability, the StabiMaxTwin uses the StabiMax ventilation mechanism and the Valk-Plus push rods. These two familiar innovations of Van der Valk Horti Systems are now being employed all over the world. The StabiMax ventilation mechanism works optimally in combination with the Valk-Plus push rod, which is customized to your specifications in an automated production process.
Calculation tool
The StabiMaxTwin ventilation mechanism is calculated in detail for every situation using the unique calculation programme WinTop. In collaboration with TNO (the top independent research institution in the Netherlands), the WinTop calculation programme was developed. On the basis of several variables (the geometry of the covering, the maximum local wind load, the preferred opening angle, etc.), all factors are calculated that could affect the reliability of the system. This concerns factors like the required construction strength, free-running of the mechanism with regard to the covering construction, and position of the rail consoles and gear racks.
