XLDriveLineScreen drive systemVan der Valk Horti Systems is introducing a new drive technique for screen systems: the XLDriveLine. It is well-known that cable-driven screen systems that are longer than 100 m are considerably less accurate. The traditional 3 mm steel cable just has too much stretch at that distance. That is why three screen systems are often placed in greenhouses with a gutter length exceeding 200 m.This is no longer necessary with the XLDriveLine. With this new technology the steel cable is largely replaced by a massive and stable steel shaft which retains top precision to a length of 150 m. So you can cover a 300 m greenhouse with just two screen sections without losing climate control.Long and strongSustainable materialsPrecise to 150 m in length with thin, solid steel shaft instead of 3 mm steel cableOnly two screen sections required for a gutter length of 300 mStainless steel cable 77 ( 4 mm) at the reversing pulleysWire tensioners are standardly fitted with plastic cable drumsEconomicalMore precision for the same priceSaving on materials like reversing pulleys and drive shaftsLess maintenance given extra strong and sustainable drive systemFewer brace sectionsDelivered in complete sections that are easy to join upKliMax XLDriveLineSpecial slide systemEffortlessly compensates for expansion and contraction of the greenhouse structureEnsures safe restriction of forces exerted on the greenhouse structureIncrease of light due to the smallest possible screen packageSustainable due to adjustment of a specially developed plastic in combination with aluminium housingWHY VAN DER VALK HORTI SYSTEMS?
