The Durr Universal 81C utilizes non-chlorinated hydrocarbons in a closed loop system to provide superior process results virtually emission free. A highly effective cleaning media non-halogenated hydrocarbons allow safe and economical use of solvents for removing oils, greases, emulsions and swarf between or after manufacturing processes. On account of its many different process variants using hot and/or cold immersion with downline vapor degreasing, the sophisticated technology of the Universal 81C cleaning system is ideal for meeting the requirements expected of modern manufacturing processes with regard to quality and functionality. Removal of large quantities of oil or swarf from mass produced parts or particles of dirt with a defined size in fine cleaning can be achieved by selecting the appropriate filtering system and other application dependent optional extras.
