Ventilator, Film-roller & Curtain Controller Cases
4G ventilators, film rollers and curtain controllers deployed at scale in vegetable and rice-seedling greenhouses: scheduled ventilation, remote curtain control and sensor-linked automatic start-stop.
Ventilator, film-roller and curtain controllers have been deployed at scale in vegetable greenhouses, rice-seedling bases and edible-fungus sheds: growers schedule ventilation and roll up/down quilts and films remotely via APP. Linked with environment meters, vents open and close automatically when greenhouse temperature exceeds limits and close automatically at night for insulation; a manual crank provides backup during power outages. Full-time guarding is no longer needed, greatly reducing labor intensity and management risk.
