Automatic roof window opener "Thermovent" for optimal ventilation.
The roof window opener "Thermovent" with its sophisticated system ensures optimal ventilation of your greenhouse.
The roof window opener works completely without electricity. Connected via a pressure cylinder, the wax contained in the cylinder pushes the piston rod forward and thus ensures the opening of the skylight.
The opening temperature can be freely adjusted between 16 and 25 degrees Celsius. The coarse adjustment is done via two holes at the end of the piston rod. Depending on the use of the pin, the roof window regulator opens sooner or later.
The fine adjustment is done via a thread at the end of the piston rod. The further the rod is screwed onto the thread, the warmer temperatures are required for opening the window regulator.
When temperatures fall down, the roof window also closes automatically. The maximum opening height of the window regulator is approx. 45cm The lifting force is approx. 7kg
The window regulator is equipped with an aluminium-zinc coating and is therefore robust against the elements.
The roof window opener is suitable for almost all roof windows of Vitavia and Pergart greenhouses. However, the "Thermovent" is not suitable for the balcony greenhouses Styx, Osiris and Ida.
The "Univent" window regulator (PER90881) is the right choice for these greenhouses, as well as for the cold frames from the Gaia series.
