Vitavia automatic window opener with thermometer - Sesame Spiro

With the Vitavia automatic window opener Sesamspiro, you effortlessly ensure optimal ventilation in your greenhouse. This clever mechanism opens and closes the greenhouse window fully automatically based on the temperature in the greenhouse. This keeps your plants protected from overheating on hot days, without you having to constantly check yourself whether the window is open or closed.

Automatic ventilation without electricity

The Sesamspiro works completely without electricity or batteries. Inside the cylinder of the window opener is a special liquid that expands when the temperature rises. This causes the window to open automatically. When the temperature drops again, the liquid shrinks and the window closes again automatically. This natural system makes the window opener reliable, energy efficient and low maintenance.

Thanks to this automatic operation, the climate in your greenhouse remains stable even when you are away from home or on vacation. Your plants always get enough fresh air, which is essential for healthy growth.

Optimal temperature control in your greenhouse

In a greenhouse, temperatures can rise quickly on sunny days. Without ventilation, this can lead to heat stress, delayed growth or even damage to your plants. The Vitavia Sesamspiro prevents this by automatically opening the window when the temperature rises.

The opener responds to a temperature range of about 16°C to 25°C, gradually ventilating the greenhouse as soon as it gets warmer. The maximum opening height is about 45 cm, providing sufficient air circulation for a healthy greenhouse climate.

This makes the Sesamspiro an indispensable accessory for any hobby gardener who wants to provide his plants with the best possible growing conditions.

Strong, durable and reliable

The Vitavia Sesamspiro is made of high-quality aluminum, making the window opener light, strong and corrosion-resistant. The mechanism has a lifting capacity of about 7 kg, making it suitable for most standard garden greenhouse skylights.

The robust design ensures that the opener will continue to function smoothly for years, even under heavy use in changing weather conditions.

Easy assembly

The automatic window opener comes with mounting hardware and can be easily mounted on the roof window of your greenhouse. In most cases, installation is quick and you don't need any complicated tools.

Once mounted, the opener works completely independently. So you no longer need to regulate anything: the ventilation system automatically adjusts to the temperature in your greenhouse.

Ideal for every greenhouse enthusiast

Whether you are a novice vegetable gardener or an experienced greenhouse enthusiast: good ventilation is essential for healthy plants. The Vitavia Sesamspiro helps you regulate the climate in your greenhouse automatically and ensures that your plants can always grow in optimal conditions.
