Our History


In 1974, George Weissenberger founded MEI to provide engineering consulting and project management to companies using bulk storage and pneumatic conveying in a variety of industries.

The result George saw was that many of his customers were experiencing a high level of system failure that stemmed from systems not designed or installed to be maintained.The company quickly began supplying total systems, installation, and system preventative maintenance services. Joined by his son Mark, a mechanical engineer, they began developing systems engineered for life.
