Ventilation is crucial when you want to regulate the temperature and humidity inside a greenhouse no matter the size. To achieve the best possible indoor climate in your greenhouse, the automatic opener will open the windows when the temperature inside the greenhouse reaches 12-15⁰ C. When the temperature drops, the window starts to close and at app. 10-12⁰ C, it will close completely. Having automatic openers on your ventilation windows prevents the temperature from getting too high damaging the plants. At the same time, the automatic openers help regulate the humidity inside the greenhouse. The automatic opener is suitable for many of our ventilation windows and various greenhouses.

The automatic opener has an arm with a metal cylinder containing wax. The wax expands as the surrounding air gets warmer pushing a piston, which then raises the window.
