Product description

Do you want to provide your plants in the greenhouse with the optimal temperature and ventilation without having to open and close the windows every day? The automatic greenhouse window opener is a practical solution that will do it for you – completely without electricity and without your intervention.

How does an automatic greenhouse window opener work?

The mechanism of operation is based on the expansion of the liquid in the working cylinder. When the temperature inside the greenhouse rises above approximately +18°C, the liquid begins to expand, causing the window to gradually open. The higher the temperature, the wider the window opens – up to a maximum angle of 45° at a temperature of approximately +25°C.

When the temperature drops, the liquid contracts and the window automatically closes, restoring stable conditions to the greenhouse.

Possibility of adjusting the opening temperature

Thanks to the adjustable working cylinder, you can adjust the moment when the window starts to open – depending on the type of plants grown and your preferences. The adjustment range allows you to increase or decrease the temperature at which ventilation begins.

Automatic operation without power supply – thermal mechanism, without electricity and batteries;
Adjustable opening temperature;

Why is it worth having an automatic window opener in the greenhouse?

Ventilation is a key element of proper cultivation of plants under covers. Too high temperature and lack of air movement can lead to inhibition of growth, fungal diseases or damage to delicate plants. The automatic opener ensures reliable ventilation even when you are not at home – taking care of the health and comfort of your crops.

Take care of the microclimate in your greenhouse – do it wisely and effortlessly!
