Screen drive technology

More and more greenhouses are using screens to maintain the ideal climate conditions. In addition, screens serve a social purpose by minimizing light pollution.

Screens are used to:
  • Protect the plants against excessive exposure to sunlight.
  • Retain heat in the greenhouse to save energy.
  • manipulate the length of the day with blackout screens for short-day plants.
  • Prevent light pollution if the supplementary lighting is switched on.

Drive system applications in screen solutions

Our screen drive systems are used in glass greenhouses, such as Venlo, open roof and wide-span greenhouses. They are also used in poly greenhouses, if the structure is sufficiently strong. The overview below shows the most common screen solutions:



Drive technology applications in screen solutions





 

Wire screen system

This system can only be used in greenhouses with a strong enough structure, such as glass greenhouses or in gutter-connected poly greenhouses. A motor gearbox drives a winding tube that winds up steel cables, opening the screen.

Push-pull system

This screen system is suitable for almost any glass and poly greenhouse, since it places lower demands on structural strength. A push-pull system uses pinion house units, gear racks and RW motor gearboxes to open and close a screen.

Roller screen system

The roller screen system can be used in a greenhouse sidewall or the greenhouse roof. Roof roller screening is practically only found in wide-span greenhouses. In roller screen applications, the drive system is mounted directly onto the sidewall or roof. Roller screen systems are also used to divide or separate areas or blocks (compartments) in a greenhouse. Ridder can provide two drive systems for this type of screening, which wind the screen onto a winding tube:

 

 

 

We can help you choose the right drive system

Ridder has developed more powerful motor gearboxes, specifically for screen purposes. These motor gearboxes are indicated by the addition of the letter 'S'. Deciding which motor gearbox will best suit your needs depends on the size and weight of the screen. We'd be happy to advise you.
