General Information
An optimal climate in the greenhouse is important for maximising yield. Balanced natural ventilation of the various sections in the greenhouse contributes to this. For this we offer a wide range of gear rack systems for Venlo greenhouses. These systems are coupled to the push-pull tubes of the ventilation system, which opens or closes the ventilation windows. We distinguish between various options.
THG truss-rail ventilation column mounting
The THG RK series is designed for mounting against the column. The systems are fitted around the column, as it were, and then clamped with bolts. A GW motor gearbox drives a shaft that is connected to the rack box and moves the rack. The gear rack then drives a push-pull tube which opens and closes windows. The rack box is equipped with an integrated 5/4" bearing plate for the counter air tube.
Advantages of column mounting
- Maximum light yield, minimum shadow.
- Very easy to install on the column.
- Ideal force transfer on the column.
- Suitable for prefabrication of drive shafts.
- Particularly suitable for lighter ventilation windows.
THG RKGC end-wall ventilation
When it comes to ventilation, it is important that the entire section is optimally ventilated and that there are no zones where the conditions are far from optimal. Venlo greenhouses and truss-rail ventilation systems have ventilation windows centrally located above the truss. This creates an area that is less well ventilated. Ventilation of the end section next to the end wall is important for optimal climate control. The THG RKGC is a Rack box specially developed for driving end-wall ventilation windows. The rack box is driven by a GW motor gearbox. The gear rack drives the push-pull tube. Standard delivery takes place by racks.
THG truss-rail ventilation truss mounting
An alternative to mounting around the column is to mount gear racks on the truss. For this we offer the THGR drive, a powerful and low-maintenance drive for ventilation in Venlo greenhouses. A GW motor gearbox drives a shaft that is connected to the rack box and moves the rack. The gear rack then drives a push-pull tube which opens and closes windows. The drive shafts are supported by glide bearing plates which are mounted on the trusses.
THG RGC end-wall ventilation
The THG RGC is a rack box and is intended for driving end-wall ventilation windows. The rack box is driven by a GW motor gearbox. The gear rack drives the push-pull tube. Standard delivery takes place using racks.
