Greenhouse – Automatic window-opener

The automatic window opener is a fully automatic device for temperature regulation.
It opens and closes the windows automatically. The window opener works mechanically, without any electrical energy and is therefore a very environmentally friendly solution for temperature regulation.

How it works:
When the air in the greenhouse warms up, the spring inside the cylinder expands and lifts the window. (At temperature between 17 and 25°C)
The warm air, which would cause heat stress to the plants, can escape through the gap.
When the air cools down, for example in the evening, the spring contracts again and the window closes, protecting the plants from the cold.

Lifts windows weighing up to 14 kg.
