ATCO's COIL-NU Foaming Cooling Coil Cleaner is formulated to penetrate and remove dirt and matted material from condenser coils and fins, eliminating the need for high pressure sprayers and bulky tank sprayers. Upon contact with the surface of the coil, the foaming action of the product begins to remove the soil from the surface. Rinsing is not required. Dirt and lint are washed away with condensation, leaving the unit cleaned and deodorized. COIL-NU is suited for use on most any coils, such as window air conditioners, roof top HVAC units, auto radiators, small air cooled equipment, small condenser and evaporator coils, metal filters, fan blades and more.
