It consists of a frame, motor, drive system, transmission system, and shading system. In the southern regions of China, the internal shading system generally only serves a shading function, similar to the external shading system. In the northern regions of China, the shading curtain of this system in the greenhouses we build is replaced with a shading and insulation curtain, which provides both insulation and shading effects. This not only reduces the cost of the greenhouse but also offers better performance.
