On January 20, 2012, the air-divided micro-heat regeneration and purifying dryer , which began operation in the Shijiazhuang refinery air separation and air-pressure plant, has been operating safely for one month. The compressed air drying effect of the air separation and micro-heat regeneration and purifying dryer is good. The dew point can be controlled below minus 45 degrees Celsius (passing below minus 40 degrees Celsius) and the lowest energy can drop below minus 80 degrees Celsius. In this way, the old dryer load is reduced, the compressed air dew point of the entire outlet is more easily controlled, and the labor intensity of employees is reduced. At the same time, the current is reduced by 10 amps on the basis of the original, saving 1,400 yuan in electricity per day. tennis shooting machine china,tennis shooting machine kit, tennis shooting machine Yi He Technology (Shenzhen) Co.,Ltd , https://www.nbball-shootingmachine.com
