FLOW-AIDE® System Descaler is a non-toxic concentrate which is certified to NSF/ANSI 60 for use as a cleaner in potable water systems. FLOW-AIDE® System Descaler is specifically designed to dissolve the toughest water scale, lime, and rust deposits from virtually any piece of water based equipment. This powerful, yet totally safe, amber colored liquid is non-toxic, non-flammable, non-hazardous, non-corrosive and biodegradable. FLOW-AIDE® System Descaler will not harm your personnel, equipment or our environment! 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.
