Windows in greenhouses
Like all the other window openers from J. Orbesen Teknik ApS, the Univent® Black opener is typically used for opening windows in greenhouses. The design with its double springs makes it very suitable for lightweight windows, since the limited weight of the window won’t assist the closing.
Due to its compact design the Univent® Black opener is perfect for opening the roof in a cold frame. The opener will take up almost no space inside the cold frame leaving plenty of room for your plants. Furthermore will the Easy-Clip-System make access into the cold frame very easy and fast.
Operating sliding doors
Because of the Easy-Clip-System the Univent® Black opener is very suitable for operating a sliding door in a greenhouse. This could be if you don’t have any windows elsewhere in the greenhouse or if you need more ventilation etc. As well as for the cold frames, the Easy-Clip-System will make access through the door a lot easier and faster.
