Macawber Engineering, Inc. has installed tens of thousands of pneumatic conveying systems worldwide. We have over 40 years of experience designing systems for a wide variety of bulk materials. We specialize in the design and engineering of low-velocity, dense phase pneumatic conveying systems. We understand how to handle materials that are fragile, abrasive, moist, lumpy or hot, and many more that cannot be handled efficiently by dilute phase systems or mechanical systems. What is Dense Phase Pneumatic Conveying? Simply - the transfer of powder, granular, lumpy, or solid materials through enclosed pipeline using high pressure gas (>15 psi) at very low velocities (2-15 ft/sec) Low velocity, fully enclosed, high efficiency, short ROI, dust free with minimal to no degradation, attrition, product separation, product loss, wear, or erosion The Experts in Dense Phase Pneumatic Conveying Systems
