Adjustable air flow control for pneumatic conveying Applications This automatic control unit enables in particular the safe operation of slow motion conveying by providing pre-calculated air quantities at any time and under any operating conditions. The small window for careful and reliable transport of solids is secured by a combination of off-the-shelf regulators and air quantity measuring instruments with a micro processor unit. Advantages Easy set point setting for required air flow Programmable conveying modes for different conveying lines Programmable conveying parameters for different product characteristics Compensation of air leakage of rotary feeder depending on conveying pressure Individual adjustments depending on conveying pressure, conveying line, rotary feeder size Integrated process for gentle purging with higher air velocities Fluctuations of mass flow up to 1:10 automatically regulated (depending on conveying length) Even suited for low mass flow in large pipes Efficiency of 95 % in comparison to 85 % with sonic chokes Noise-optimised Automatic pressure control for safe relief of high pressure and pressure peaks Interface to main controls with Profibus DP, digital in-/output or as stand alone unit
