Macawber Engineering Inc. has stayed true to it’s core for over 40 years. While other companies have been distracted by diversification and/or been taken over by larger companies, Macawber has stayed on the course for becoming an expert in everything related to low velocity, dense-phase pneumatic conveying, frequently called in to deal with difficult to handle materials and to solve unique customer requirements. Our reputation is attributed to our high standards in everything that we do from paying detailed attention to our customers’ needs to reliable and efficient designs, high quality products and customer service. We truly know what it takes and take great pride in it.
Technology: Low Velocity
Our technology excels due to our knowledge and experience in low velocity pneumatic conveying. Low velocity, dense-phase pneumatic conveying is the preferred method for many materials handling processes as almost all applications benefit from a regime that that provides the heaviest line loading and the lowest material velocity. These attributes also provide the greatest conveying gas economies for efficient power consumption. The applications that often benefit most from low velocity are related to materials that are difficult to handle with more conventional methods such as mechanical and dilute conveying systems. In the case of fragile and abrasive materials where eliminating material degradation and wear are important, material is conveyed at 1-3meters/seconds. The main benefits of low velosity conveying are:
* Low air and energy consumption
* No or minimal material degradation
* No or minimal component, pipe and bend wear
* No or minimal material segregation
Our 40-year experience extends to just about every process industry from food to minerals, combustion to chemicals and others, with the ability to handle thousands of materials from pebble lime to peanuts, biomass ash to baby powder. To-date we has installed over 25,000 systems worldwide, many of which have remained in operation for decades providing an excellent return for investment. The best systems are designed by people who truly know what they are doing.
Macawber systems are designed in-house with quality, flexibility, reliability and efficiently in mind. We realize that every requirement is unique and therefore, our equipment is designed to be able to accommodate. Our systems come in different sizes, materials of construction, control options, design pressures and are able to handle temperatures up to 350C and with special design considerations, even higher. We offer a wide range of proprietary ancillary equipment to complement our pneumatic conveying eqipment. And once a scope has been agreed, we can offer installation services.
* Low maintenance with only one moving part
* Robust proprietary Dome Valve in the heart of the system
* User-friendly with simple operations and fully automated controls
* Only few spare parts required
* Limited downtime
* No pipeline air boosters
* Simple installation and retrofit
*Enviromentally friendly; no spillage or dust
Due to our strong focus on quality in system design and our extensive experience we are able to offer a 24 month warranty (terms and conditions apply) which exceeds the standard industry warranty of 12 months, a benefit that add value. We manage several quality programs addressing product quality, product safety and management performance:
* ISO 9001 Compliant
*ASME Section VIII Certified
*CE Marked (via sister company, Mactenn Systems Ltd.)
Our philosophy is a scientific approach continuously testing new materials be it for our own purposes to better understand and improve our designs or to carry out customer witness testing to demonstrate how their unique material/s will perform in our equipment. We can adapt our tests to closely match the expected conditions on your site. Having a clear understanding of your material’s behavior in our equipment ensures that your system works right the first time, every time. The purpose-built full size R&D centre and test facility incorporates a materials characterization laboratory for detailed examination of the mechanical properties of bulk materials.
