WINDOW OPENER IN DOOR

Two types of openers are available: for a hatch in the roof and a window in the door. An automatic ventilation window opener for a greenhouse is a convenient device that does not require power. The principle of operation of such a device is the expansion of a special liquid under the influence of solar heat. The liquid pushes out a rod, which transfers force to the lever, which in turn raises the window. When it cools, the liquid contracts and the springs pull the rod back into the cylinder, and thus the ventilation window closes. The start of the ventilation window opening is regulated in the range from 16 to 24 ° C.

The automatic ventilation device will save the crop when you are not on site or simply relieve you of the routine work of constantly opening and closing the window manually.
