Stainless Steel Automatic Greenhouse Window Opener

Automatic Temperature Control for Healthier Plants

Maintain a stable growing environment in your greenhouse with this Stainless Steel Automatic Greenhouse Window Opener. Designed for reliable, unattended operation, it opens and closes your roof or side windows based on temperature changes, helping to protect plants from overheating and sudden temperature swings. The robust stainless-steel construction offers excellent resistance to rust and corrosion, making it suitable for long-term use in humid greenhouse conditions.

This opener operates entirely without electricity or batteries. A temperature-sensitive cylinder expands and contracts with heat, automatically adjusting the window angle as the temperature rises or falls. It begins to respond from around 5°C (41°F) and provides effective ventilation control within an approximate working range of 5-25°C (41-77°F). Suitable for windows up to 7 kg (15 lbs), it comes with mounting clamps, screws, and a clear instruction manual for straightforward installation on most standard greenhouse frames.
