• Machine Surface Cleaning Solutions

Maintaining clean surfaces of papermaking equipment is critical to operating a machine without defects and breaks. The paper machine wet-end is prone to deposition of scales, biological slimes, process additives, and fiber. The dryer section is prone to a buildup of grease, oils, and paper dust, which can become a flammability hazard. Coaters and size press must be clean to avoid sheet defects and breaks.

DuBois will work closely with your employees to ensure the proper procedures and trainings are established for safe and efficient foam/gel cleaning. DuBois can also provide equipment suited to your cleaning needs.
