The LV 7R/B and LV 20 R/B aluminum racks form part of the DGT-Volmatic
vent opening system for greenhouse vents. The patented racks are based on
more than 40 years experience in development and production of rack-and-
pinion opening systems, and they are consequently thoroughly tested products.
Solid and reliable
The meshes are placed as close as possible to the drive shaft, whereby a
reduced torque and a reduced twist of the shaft is obtained. This secures a
uniform opening/closing of entire vent rows resulting in large energy savings.
Besides less torque is required, for which reason smaller gear motors can
be used.
Curved racks
Curved racks LV 7B and LV 20B are ideal for e.g. side vents, or where the
screen system owing to consideration of space calls for this. |
