The electric film roller is a motorized device specifically designed for rolling and unfolding insulation film or shade nets on side or top windows of greenhouse structures. Powered by an electric motor, it replaces traditional manual cranks, enabling effortless and efficient control over the opening and closing of greenhouse films. This facilitates precise management of indoor temperature, humidity, and air circulation.
Its core operating principle involves the motor converting high-speed, low-torque power into low-speed, high-torque output via a reduction gear. This drives the film-rolling rod connected to the output shaft, rolling or unrolling the film. Users simply issue commands via buttons or a mobile app to complete ventilation for the entire greenhouse within minutes.
Core Advantages of Electric Film Rollers
Labor-saving and Effort-reducing, Doubling Efficiency: This is the most tangible benefit. With one-button operation, a single person can manage ventilation for dozens or even hundreds of greenhouses, significantly reducing labor intensity and dependence on manual labor—ideal for large-scale multi-span greenhouse complexes.
Timely and Uniform Ventilation: Electric film rollers enable synchronized, uniform opening and closing across all greenhouses, eliminating uneven ventilation caused by inconsistent manual operation sequences and speeds. During sudden weather changes, it responds swiftly to protect crops from high temperature and humidity damage.
Seamless Integration with Smart Controls: This is its revolutionary advantage. Electric film rollers easily integrate into greenhouse environmental automation systems. By linking with temperature, humidity, rainfall, and wind speed sensors, the system achieves fully automated ventilation based on preset environmental thresholds.
For example: When indoor temperature exceeds 30°C, the system automatically opens the film; during rainfall or excessive wind, it closes automatically. This achieves true “unmanned” precision management.
Enhanced safety: Eliminates the safety risks for operators climbing to manually roll films during rain, snow, or nighttime.
