D’Scale™ Purple Acid Scale Remover by DiversiTech is a professional-grade descaling solution engineered for cooling towers and industrial water systems where scale buildup reduces efficiency and heat transfer.
This non-foaming acid formulation safely dissolves mineral scale without producing corrosive acidic foam, making it ideal for HVAC and facility maintenance applications. D’Scale Purple features a built-in pH indicator dye that changes color from purple to yellow, clearly signaling when the acid has been fully consumed.
Each 1-gallon container dissolves up to 3 pounds of scale, helping restore system efficiency, improve water flow, and extend equipment life.
Trusted by HVAC technicians and water-treatment professionals, D’Scale Purple delivers controlled, visible, and effective scale removal.
