VpCI®-648 is a water treatment additive designed for corrosion protection of ferrous metals and copper at low dosages in deionized or reverse osmosis water. Based solely on organic components, VpCI®-648 does not contain nitrites or any halogen counter ions. At recommended dosages, VpCI®-648 does not significantly contribute to the conductivity of water systems. VpCI®-648 is intended for water cooled generator stators but is also applicable to other cooling water systems containing copper or steel where low conductivity is required. A ferrous-only version, VpCI®- 648 FO, is also available.

Package: VpCI®-648 is available in 5 gallon (19 L) pails, 55 gallon (208 L) drums, liquid totes, and bulk. To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F(4-38 °C). Shelf life: 2 years
