Charter Machine Company

Charter Machine Company (CMC) is a division of Graphic Equipment Corporation (GEC) which was incorporated in 1968. Beginning primarily in the printing industry, they designed and patented the Turret Rewinder used not only in the U.S., but worldwide including: Australia, France, Japan, Germany, Brazil, and Canada.

Roediger contracted CMC in 2003 to manufacture all their dewatering equipment, utilising specifications and designs, subsequently purchasing Roediger in 2006. The current engineering department has over 40 years experience concerning Roediger designs. Expanding in the the dewatering industry has proved a perfect fit for the Charter Machine Company in both growth and diversification.


Gravity Belt Thickener


A highly effective tool for de-watering, it operates quietly at a minimal cost, consuming a low volume of wash water.  Sludge is flocculated by the use of polymers, introduced on the belt and the released water is drained through the gravity belt.  While the process is simple, the decrease in sludge volume is impressive. Our Gravity Belt Thickeners (GBT) reduce the volume of thin sludges and slurries produced during municipal or industrial wastewater treatment. The principle of the GBT is simple: Sludge is flocculated with polymers and the released water is drained by gravity through a traveling filter belt.
