Automatic greenhouse window opener without electricity

Automatic window opener - optimum ventilation without electricity: On warm days, the greenhouse heats up quickly and the plants can get too warm. You then have to provide fresh air and cooling. To avoid always having to go into the greenhouse yourself to open the windows, use our automatic window opener. It works completely without electricity. This not only saves energy costs, but also makes installation simple and straightforward.

The ingenious way the window opener works: the window opener contains an oil that expands at 22 degrees Celsius and pushes the mechanism upwards, pushing the window open. When the temperature drops, the oil contracts again and the window closes. You no longer need to worry about anything.

Always the optimum climate in the greenhouse: By reliably opening and closing the windows, the window opener ensures the ideal climate in your greenhouse. Excessively high temperatures and stagnant heat, which can damage your plants, are prevented. So you don't have to worry about your plants - even when you're not at home. Optimal air circulation also promotes the exchange of oxygen and CO2, which is essential for healthy plants.
