CertifiedNSF/ANSI 60 Non-Corrosive Non-Toxic Fully Biodegradable* Safe to Handle IMPROVE EQUIPMENT EFFICIENCY:Water scale deposits are a significant cause of heat transfer loss, along with the subsequent increase in energy costs. In fact, even a thin layer of scale (1/32') can cause a 30% increase in the cost to operate that piece of equipment. Keeping the heating passages free of mineral deposits significantly improves efficiency, conserves energy, extends the useful life of the equipment, and saves you time & money.
