Ridder - Solutions Poly Greenhouses

Ridder offers a suitable ventilation system for each greenhouse construction also for Poly Greenhouses.
The drive systems and drive components of Ridder Drive Systems, which are applicable in continuous ventilation systems that are directly driven by Ridder products. In case of ventilation systems with vents, the vents are opened and closed by rack drives which are directly mounted to the vents. In case of ventilation rollup systems, the rollup systems are directly operated by cardan shafts or RW motor gearboxes.
For these systems, Ridder Drive Systems has standard and special or customized drive components and systems available.
Rollup ridge ventilation system poly house
Besides poly houses with vents, also there are poly houses with a vertical ventilation opening equipped with a roll up system for opening and closing the ventilation opening in top of the greenhouse. For the opening and closing by means of rolling up, Ridder Drive Systems has cardan shafts available that are being connected to a drive system.
For operating these rollup ventilation systems, Ridder Drive Systems distinguishes a direct and an indirect driven system. A directly driven system is where the cardanshafts are mounted directly to a motor gearbox. With an indirectly driven system the cardan shafts are mounted to square headed gearboxes. Several of these gearboxes are driven by one motor gearbox in this case.
Rollup side wall ventilation system poly house
In poly houses it can be the case that the end walls of the greenhouse can be opened and closed to achieve more ventilation in the greenhouse. For this mostly rollup systems are being used at which plastic foil is being rolled up on a (winding) tube. For driving these (winding) tubes for instance cardan shafts are being used in combination with a fixed mounted motor gearbox. In such a system, the motor gearbox with one cardan shaft can be mounted at the end of a rollup system.
Also it is possible to mount the motor gearbox in the middle of the rollup system. In this case on both sides of the motor gearbox a cardan shaft is mounted. Another manner for operating rollup ventilation walls is by means of connecting a motor gearbox directly to the (winding) tube. In this case the motor gearbox has to be connected to a guiding system for making it possible that the motor gearbox moves with the (winding) tube during the rollup. For a good functioning of the rollup system a weight compensation of the motor gearbox is necessary. Motor gearboxes of Ridder Drive Systems are being used for this kind of systems. The guiding units and weight compensation must be provided by the greenhouse builder or installer.
