Automatic louvre opener – We believe in high quality products and quality service.

J. Orbesen Teknik ApS has focus on window openers for hobby greenhouses and has been the core business since 1981. In those +30 years, we have become the market leader for window openers, and are currently exporting the openers to all over the world.
The core technology in the opener is the hydraulic cylinder that contains a plant-based wax. The special designed cylinder containing this wax, works as the greenhouse window openers thermostat, thus there is no need for electrical power supply.

Sesam Liberty® is a universal opener that will open and close the louvers in your jalousie window.

The opener can replace all existing both manual and automatic operated louver openers. Still with the automatic Sesam Liberty® opener installed, it is possible very easy to disconnect the hydraulic cylinder, and operate the louvers manually. It uses our standard hydraulic cylinder, which is also used in our small range openers.
