Better Engineering Mfg.’s new Drum Washer System is designed to clean and dry parts that other parts washers can’t—complex screw machine parts and parts with blind holes and intricate passage ways. The parts washer features a rotary drum available in diameters 12 – 48 inches with a continuously welded helix, height and pitch as needed. The drum is positively driven with a chain. The drive motor is variable speed (1-5 RPM’s) and is protected by an electronic “smart drive” torque overload sensor. Modular systems can be expanded or changed without a torch or welder. Customers can specify spray or immersion in the wash and rinse modules. With few exceptions, all wetted parts are stainless steel, and the drying modules use high volume airflow bgenerated by a centrifugal blower, recirculated to conserve energy and to avoid air blowout.
