Award-winning dross recovery
13 December 2010
EVS International worked with the market to gain feedback from which to develop its solder dross recovery solutions.
The new EVS 7000 and EVS 9000 are a culmination of this process and offer manufacturers a reduced footprint, advanced electronic controls and integrated diagnostics.
The EVS7000 offers a capacity of 10kg/20lb and the EVS 9000 offers a capacity of 20kg/40lbs and has the ability for single operation de-drossing of even the largest wave soldering machines.
Its integrated hopper makes rapid transfer of dross simpler and safer, and speeds de-drossing times by up to 75%.
This provides a cleaner wave with less maintenance, less downtime and a reduction in shorts and bridging, as well as the potential to discontinue the use of messy wave oils and/or dross reduction powders.
The process uses heat and pressure inside a magnetised cylinder to separate and return pure solder into an ingot tray. The remainder of the material is automatically ejected down a sealed chute into a dross bucket. Hundreds of solder assays prove that the recovered pure solder is exactly the same specification as the solder in the WSM pot. This has been authenticated by the solder manufacturers and confirmed by the International Tin Research Institute.
The system offers the benefit of a rapid return on investment by recovering 50% - 70% pure solder from dross, with savings of up to 50% in solder costs. The system provides a self-contained process to reduce the handling of dross and uses no chemicals, additives or toxic substances. In addition, the new High Solids Filtration System on the EVS 9000 increases air flow and dust/smoke capture, while maintaining the small footprint of the new four wheel steer cart with its pull-out service drawer. The system is complete with an LED monitoring system that shows a green light for normal running, an amber light when 75% of the combination filter is used and a red light when the combination filter should be changed.
The EVS 7000 and EVS 9000 will help a company to attain and retain ISO14001 accreditation with the added benefit of improving wave solder machine effectiveness. These new solutions follow hot on the heels of EVS International’s EVS 1000, which gained global approval with multiple industry awards, including Product of the Year at the most recent Productronica.
EVS 7000 and EVS 9000 come in a lead or lead free version making these new EVS Solder Recovery Systems attractive to customers looking to save money on solder purchases.
