The "SA-K Series" is an agricultural CO2 controller that works in conjunction with CO2 generators to maintain the CO2 concentration in greenhouses at appropriate levels. When the ventilation windows are open, it applies zero concentration difference CO2, and when the windows are closed, it applies high concentration CO2, allowing for automatic switching control (managed by a single CO2 sensor). 【What is zero concentration difference application?】 This is the application of CO2 that brings the indoor and outdoor CO2 concentration difference to zero. Even with the windows open, during photosynthesis, the indoor CO2 concentration decreases (250-350 ppm) compared to the outdoor air (400-450 ppm), resulting in about a 20% reduction in photosynthesis compared to using outdoor air. With zero concentration difference application, CO2 is absorbed by plants without waste, enabling photosynthesis to occur with nearly 100% efficiency. 【What is high concentration CO2 application?】 By setting the indoor CO2 concentration to a high level (700-1000 ppm), it can further promote the photosynthesis of crops. 【Recommended for those who:】 ■ Find it cumbersome to manage CO2 concentration in greenhouses ■ Want to improve production efficiency 【Benefits of introduction】 ■ Reduction of labor in operations ■ Improvement in plant production efficiency *For more details, please refer to the PDF materials or feel free to contact us.
