Storm Automatic Door & Window Opener
Ensure your greenhouse maintains the perfect climate with the Janssens Storm Automatic Door & Window Opener. Designed for convenience and efficiency, this opener automatically regulates the temperature inside your greenhouse by opening and closing windows without the need for manual intervention or external power.
The secret lies in the temperature-sensitive gel contained in the cylinder, which expands as temperatures rise, lifting the window to allow fresh air in, and contracts as it cools, closing the window to retain warmth. Ideal for those times when you're away or can't tend to your greenhouse, this maintenance-free device is a must-have for busy gardeners.
For optimal airflow, we recommend installing at least two openers on opposite sides of the roof to ensure efficient air circulation. The Storm Opener is built to withstand harsh conditions, including strong winds, thanks to its durable construction, reinforced piston, and additional shock absorber.
This robust opener can lift windows weighing up to 12 kg and begins to open at temperatures between 17-25ºC, reaching full opening at 30-32ºC. With a maximum opening height of 38-40 cm, it offers excellent ventilation for your plants.
Crafted from painted aluminum, it is available in a sleek black lacquered finish. For long-term durability, the manufacturer recommends unscrewing the opener cylinder during the winter months.
