Orival filters are thoroughly proven in filtration of cooling water for continuous casting, hot rolling, cold rolling and non-ferrous metal production. Remove scale, airborne particles, sand, silt, etc. from re-circulated and once-through water which cause quality problems such as black digs. Provide reduction in maintenance and operating costs by protecting spray nozzles from clogging. Unlike sand filters, Orival filters are unaffected by the presence of oil in the water. Filters clean themselves automatically while providing uninterrupted flow of water to the process. Individual filters up to 12,000 gpm; unlimited flow rate capability. ASME U-Stamp, oil-resistant, high-pressure and high-temperature units available.
