In roof ventilation, a drive system opens a continuous ventilation flap. The multi-tunnel is a structure consisting of several interconnected tunnels. These tunnels can integrate various ventilation systems, including roof ventilation, side flaps or sliding ventilation. 

The multi-tunnel allows precise adjustment of ventilation along the entire length of the structure. This is particularly useful in large greenhouses where different plant zones exist, and individual climate requirements must be met.

  • Large and long ventilation length possible
  • Affordable ventilation system
  • Saving in number of drives possible through group ventilation
  • Time saving during assembly
