Extra clean wire at high speed The BHW wire cleaning system is used in the most demanding applications, allowing extreme high cleaning speed, with all carbon steel wires (including 0.90%C), mechanically descaled or acid cleaned, bare or pre-coated, drawn with calcium or sodium lubricants.

density ultra-fine brush bristles providing hydro dynamic cavitations at bristles/ wire interface 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. The BHW system cleans drawn wire from lubricant residue in applications prior to heat treatment or coating, including galvanising, annealing, patenting, plating, welding (chain, mesh), painting, plastic coating, Al or Cu cladding, etc. In a typical application, the 2.6 mm (0.102") drawn wire is cleaned in-line at 12 m/s (2,400 ft/min) with 4 or 5 x BHW units, obtaining an extra clean wire, enabling direct galvanising and other metallic or plastic coatings.

The particularly recommended for cleaning applications in which a conventional process is inappropriate, especially with wires drawn upon severe conditions resulting in increased heat and burned lubricant tightly bound to the wire surface and embedded in micro-cavities. The BHW system provides the ultimate combination of simplicity and effectiveness: Acid-free, caustic-free, without ultrasonic and chemicals. Economical and environmentally friendly, this completely ‘green’ system provides significant process savings in production of clean H/C and L/C wires. BHW system is

The BHW system incorporates new technology which enables normal plant cold water to be converted into the most unique “micro-abrading liquid” agent used for cleaning of dry 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
