single-channel all-steel fume hood variable air volume butterfly valve control:

       1, using SM6 surface wind speed sensor, real-time measurement of equipment surface wind speed, feedback control of the fume hood exhaust valve;

       2, to maintain a constant wind speed on the equipment surface, the system response time is <3 seconds.

        2-wayAll steel fume hoodVariable air volume butterfly valve control:

       1 uses SM6 surface wind speed sensor and SM2 displacement sensor to simultaneously detect the adjustment window displacement and real-time surface wind speed;

       2. Quick response control through displacement measurement, within <2 seconds;

       3. Adjust the precision high-pressure independent butterfly valve to the preset exhaust volume position;

       4. After the adjustment window stabilizes (Boost Duration can be set, such as 3 seconds), switch to face air speed control to deal with equipment turbulence and maintain the leakage rate of the fume hood;

       5, system response time <2 seconds.

        adaptive all-steel fume hood variable air volume butterfly valve control:

       1. Use SM10 area status sensor to detect whether there is an operator in front of the equipment;

       2. When there are no operators in front of the equipment, reduce the surface wind speed setting of the fume hood to 0.3m/s. Once someone is detected, quickly adjust the surface wind speed to 0.5m/s;

       3. Significantly reduce equipment energy consumption.
