Key features - Full opening angle: about 30 degrees when fully open, adjustable depending on setup and load - Maximum opening height: about 45 cm for the window - Designed to ensure that your greenhouse window opens normally - Important notice: Automatic ventilation cannot be used at temperatures above 50 C (122 F) Benefits and practical value - Clear ventilation range: know exactly how far the window can open both in angle and height - Reliable operation: designed to work with greenhouse windows to support normal opening behavior - Temperature-aware use: the system includes an upper limit for automatic ventilation to protect plants and equipment What it solves - Provides a defined and controllable opening to improve air exchange and reduce heat buildup - Helps maintain a healthier greenhouse environment by enabling consistent ventilation without guesswork - Helps prevent condensation and stale air by enabling regular airflow through the window Typical use scenarios - Summer heat control: use the full opening to vent hot air on sunny days, helping to keep temperatures at humane levels for plants - Humidity management: during damp mornings or periods of high humidity, opening the window up to 45 cm aids air renewal and moisture balance - Routine window operation: when opening or inspecting the greenhouse, the mechanism is designed to ensure the window opens normally for access and airflow Notes - The specified angles and heights are approximate and depend on adjustment and load - Automatic ventilation should not be used when ambient temperatures exceed 50 C (122 F)
