The Continuous Window Opening System is the centerpiece of a crop-friendly environment that provides natural ventilation to the greenhouse. By adjusting the window opening angle through the gear motor and driving the ventilation window to a precise angle, the ventilation area of the greenhouse is greatly increased, lowering the temperature and humidity inside the greenhouse, creating a suitable environment for plant growth, and at the same time utilizing the convection of the air in nature to reduce the temperature and humidity inside the greenhouse, which fully saves on the operation cost.
