Better ventilated with Kesser

Our automatic window opener is an innovative and practical support that is perfect for garden and greenhouses made of wood or aluminium. It allows better ventilation of the greenhouse by automatically opening and closing the window depending on how the temperature is inside the greenhouse.

The piston of the cylinder moves depending on the temperature and opens or closes the window automatically. This means you no longer have to go to the window to manually open or close. The automatic window drive also saves money thanks to its function, as unnecessary heat loss is avoided.

The opening angle can be easily adjusted by turning the cylinder. This allows you to tailor the ventilation of the greenhouse exactly to your needs. The window regulator reacts to temperature changes and automatically opens or closes the window in a temperature range of approx. 16-35°C

Another great feature of the automatic window opener is that it does not require any electricity or batteries. This is not only practical, but also good for the environment. You can easily install the smart window system in standard greenhouses, instructions for quick and uncomplicated installation are included. Overall, the Kesser automatic roof fan is a useful and practical addition to any garden or greenhouse, which allows automatic control of the ventilation and avoids unnecessary heat loss.
