ValkCabrio | Ventilation Mechanism

 

A cabrio greenhouse combines the advantages of cultivating in a greenhouse with the advantages of cultivating outdoors. But then it must be possible to open the greenhouse roof fully and retain stability.


The ValkCabrio vent push rod/rail system of Van der Valk Horti Systems meets this need effortlessly. The system is distinguished by two push/pull tubes placed above or next to each other and a unique patented telescope construction for maximum ventilation possibilities.

Common properties

of the ValkCabrio types 2, 3 and 4

  • Stronger due to larger diameter of push/pull tubes
  • Larger ventilation sections with fewer motors and less wiring
  • Unique calculation program: - calculated in detail for every situation

- developed in collaboration with TNO Bouw
- calculates forces exerted on the entire system

ValkCabrio type 2

Two push/pull tubes above each other

 

  • Set of push rods move simultaneously on the upper and lower tube
  • Is combined with Valk-Plus vent push rods and StabiMax hinge element
  • The screen can sit freely against the truss
  • Screening on upper beam possible
  • Double consoles
  • Guaranteed ‘free-running' of the push rods
  • Calculation programme calculates the space required between the two sets of push rods 

 

ValkCabrio type 3

Two push/pull tubes next to each other

 

  • Simultaneous movement of steel push rod tube left and right of the truss
  • Option with aluminium Delta vent push rods
  • Single consoles
  • Consoles symmetrically positioned
  • NB: for screening on the upper beam, the consoles have to be raised 

 

ValkCabrio type 4

Two push/pull tubes next to each other and overlapping greenhouse covering

 

  • Same as ValkCabrio type 3, but with more travel due to the asymmetric position of consoles
  • Prevents rain entering due to overlapping greenhouse covering
  • NB: for screening on the upper beam, the consoles have to be raised 

 

Telescope construction: minimal forces

Van der Valk Horti Systems developed a clever telescope construction (patented) for the ends of the push/pull tubes.

 

With this fully rolling construction, greater travel distances are realised, without having to tilt the push/pull tube.
Result: minimal forces exerted on the greenhouse construction. 

Sustainable

For the required stability, the ValkCabrio type 2 ventilation mechanism use the StabiMax ventilation systems and the Valk-Plus push rods. These two familiar innovations of Van der Valk Horti Systems are now being employed all over the world.

 

For the required stability, the ValkCabrio types 3 and 4 ventilation mechanism use steel push rods. Option to fit with aluminium Delta push rods.
