Macawber Engineering, Inc. specializes in the design and engineering of low-velocity, dense-phase pneumatic conveying systems for all bulk materials in industry. We understand how to handle materials that are fragile, abrasive, moist, lumpy or hot. These types of materials can not be handled efficiently by dilute-phase systems or cleanly by mechanical type systems.

We also design and manufacture pressure valves – including the Dome Valve capable of operating in harsh and abrasive environments; pressure vessels to many world-wide standards; and shot blast systems featuring media recovery. We have over 35 years of experience with tens of thousands of installations in all types of process industries worldwide.

We provide the most environmentally responsible and energy efficient pneumatic conveying solutions in industry.

Understanding pneumatic conveying systems makes vital decisions easier. From pebble lime to peanuts, from coal to baby powder – and everything in between – Macawber has the technology, the hardware, and the experience to design and supply the highest quality system.
