The system is used in the most demanding applications, allowing the highest cleaning speed, with all carbon steel wires (including 0.85%C), mechanically descaled or acid cleaned, bare or pre-coated, drawn with calcium or sodium lubricants. particularly recommended for cleaning applications in which a conventional process is inappropriate, especially with wires drawn in severe conditions resulting in increased heat and burnt lubricant tightly bound to the wire surface and embedded in micro cavities. BHW wire cleaning The BHW system is The BHW system incorporates new technology which enables normal plant water to be converted into the most unique “micro-abrading liquid” agent used for cleaning of drawn wire, in-line, at high speed, at virtually zero energy consumption, providing extra-clean wire.

Basically, it is a sensitive multi-layer displace/fine scrub/flush cleaning system, benefiting from water immersed high density ultra-fine bristles performing as porous long-life abrading pads that smoothly impact wire surface separating lubricant residue from base material, washing away dispersed contaminants by moving wire, exiting the unit very clean of white-metal appearance. At exit, the system can be fitted with the PWC (Pressure Wet Cleaning) unit for complete removal of residual moisture
