Macawber Engineering, Inc.

For over 45 years, our focus has been to become an expert in dense phase pneumatic conveying, to understand the processes and flow characteristics of materials, to design high-quality systems, and offer our customers long-term solutions and value.

Today, we are known for our expertise in conveying materials of all kinds with unique capabilities to handle difficult to convey materials. Many materials that are fragile, abrasive, damp, lumpy, or hot cannot be handled efficiently by dilute phase systems or cleanly by mechanical type systems. We offer the required expertise and experience to convey these materials, and many others, successfully coupled with system designs developed over years that improve the overall benefits of dense phase pneumatic conveying.

We offer the most environmentally responsible and energy efficient pneumatic conveying solutions.
