It automatically opens and closes windows based on temperature, ensuring your plants thrive without the need for electricity. With a robust construction and impressive weight capacity, this opener is the perfect addition to any gardening toolkit. ## Description Product Description Automatic greenhouse window opener. The automatic opening device has been designed to automatically control the temperature and provide additional ventilation for all our greenhouses. As the air inside the greenhouse heats up, the ventilation gradually opens to allow the right amount of air in the greenhouse and closes when the optimum temperature is reached. The ventilation arm has been designed using wax that expands under the effect of heat to push a piston, which lifts the window when the air warms up, then contracts when it cools, closing with a spring. The automatic vent opener works on solar energy. Note: IMPORTANT: Do not use this opening system where temperatures are above 60°C. Please make sure your greenhouse window can be opened freely by at least 45 cm. Get the best from your greenhouse plants and vegetables, don't let it happen! Package includes: 1 x Automatic Window Opener 1 x Step by Step Installation Manual Safety Warning Do not use this opener where temperatures exceed 60°C. Ensure your greenhouse window can be opened freely by at least 45 cm. Do not use it where temperatures will exceed 45°C (122F). Always follow the installation manual for safe assembly and use. Review: Brilliant. - Having just put together our greenhouse, I'd seen these auto vents and wondered if they'd fit an aluminium greenhouse vent window. I ordered this one as some of the others on desertcart stated they were capable of opening some serious weight vents and as ours is light I was worried they may have been too strong. It works amazingly well opening the vent a good 10"/250mm maximum and closes fully to seal the vent efficiently. We now don't have to argue who's going to go out and open/close the vent 😀 Review: Does the job but fiddly to fit - It opens and closes my greenhouse window - so I cannot complain about that, it functions as expected. Fitting it however was a little fiddly resulting in much swearing from my other half! ## Features - SUITABLE FOR MOST GREENHOUSE - This window opener will automatically open and close your greenhouse window to maintain the best growing temperature and prevent your greenhouse from overheating. - QUALITY CONSTRUCTION - Reliable automatic window opener made of anodized aluminium for greenhouses. - Operating conditions: opening start: 15°C to 23°C. Full opening temperature: 35°C or above. Full Opening Distance: 45cm Maximum opening weight: 7 kg. - Mechanical system: need electricity supply, automatically responds to weather changes, no need to stay near the greenhouse. - Hinweis: Verwenden Sie diesen Öffner nicht bei Temperaturen über 45 ° (122F). Um mit dem Gewächshaus zu arbeiten, müssen Sie die Bohrwerkzeuge verwenden, um in den Kanal zu schrauben und ihn zu befestigen. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071ZZJMXJ | | Best Sellers Rank | 277,110 in Garden ( See Top 100 in Garden ) 99 in Greenhouse Window Openers | | Brand Name | IRYNA | | Colour | Clear | | Cover Material | Plastic | | Customer Reviews | 4.1 4.1 out of 5 stars (125) | | Frame Material | Aluminium | | Manufacturer | WIWIR | | Number Of Vents | 1 | | Number of Doors | 1 | | UPC | 615284689539 | ## Product Details - **Brand:** IRYNA - **Colour:** Clear - **Cover material:** Plastic - **Frame material:** Aluminium - **Number of doors:** 1 ## Images ![Window Opener, Single Vent Automatic Spring Opener, Automatic Greenhouse, Window Opener for Roof Skylight, for Small Greenhouse Garden - Image 1](https://m.media-amazon.com/images/I/71hIYHDxQlL.jpg) ![Window Opener, Single Vent Automatic Spring Opener, Automatic Greenhouse, Window Opener for Roof Skylight, for Small Greenhouse Garden - Image 2](https://m.media-amazon.com/images/I/51TEniozTfL.jpg) ![Window Opener, Single Vent Automatic Spring Opener, Automatic Greenhouse, Window Opener for Roof Skylight, for Small Greenhouse Garden - Image 3](https://m.media-amazon.com/images/I/51mRES4DedL.jpg) ![Window Opener, Single Vent Automatic Spring Opener, Automatic Greenhouse, Window Opener for Roof Skylight, for Small Greenhouse Garden - Image 4](https://m.media-amazon.com/images/I/61K0Ux+2AmL.jpg) ![Window Opener, Single Vent Automatic Spring Opener, Automatic Greenhouse, Window Opener for Roof Skylight, for Small Greenhouse Garden - Image 5](https://m.media-amazon.com/images/I/510BS9HUU1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant. *by J***T on 3 August 2023* Having just put together our greenhouse, I'd seen these auto vents and wondered if they'd fit an aluminium greenhouse vent window.
