COIL CLEANER NA is a blend of surfactants, water-based solvents, alkaline detergents and derusters especially formulated to melt away oily deposits and dissolve scale from heat transfer surfaces such as those found in boilers, air conditioner units, and other types of heat exchangers. When applied as directed, COIL CLEANER NA will immediately begin removing dirt, oil, and scale with a unique foaming action that pushes the soils away from the surfaces so they may be rinsed way easily. COIL CLEANER NA contains a high level of alkaline salts and special care should be used when cleaning aluminum. Available in UN approved 5 gallon pails, 55 gallon drums and bulk quantities.
