Nu-Calgon 4167-08 Eco-Lyme Descaler Gallon – Eco-Friendly HVAC & Boiler

Nu‑Calgon Eco‑Lyme is a powerful, professional-grade descaler engineered for HVAC/R systems, boilers, evaporative condensers, cooling towers, and industrial water-handling equipment. It combines top-tier descale performance with an environmentally responsible, user-safe formula. Features: Strong yet Safe on Metals: Eco-Lyme delivers descaling power comparable to hydrochloric acid — dissolving stubborn scale, rust, and mineral deposits — but with much lower corrosion risk. It’s safe for carbon steel, stainless steel, aluminum, copper, iron, brass, and many other common HVAC metals. Environmentally Friendly & Biodegradable: The formula meets the biodegradability standard of OECD 301A, making it an excellent “green” descaler choice for contractors and facilities managers who care about environmental impact. Odorless, Low-Foaming, and Easy to Handle: Designed to minimize hazards for technicians — no strong fumes, excessive foam, or unpleasant odors. Versatile Use Across Systems: Ideal for descaling cooling towers, hot water boilers, evaporative coolers, processing equipment, condensers, and many other water-circulation systems. Performance & Longevity Gains: By removing scale buildup, Eco-Lyme helps restore water flow and heat transfer efficiency — reducing refrigerant high-side pressure in HVAC systems, cutting down compressor load, lowering energy costs, and extending equipment lifespan.
