Nu-calgon 4162-77 Soak-n-solv Restoring Solution

Product Description

The NU-CALGON 4162-77 is a restoring solution formulated to remove heavy soils, oxidation, and buildup from HVAC coils, heat exchangers, and related components. The solution works by soaking into fouled surfaces and loosening contaminants that restrict airflow and reduce system efficiency. HVAC technicians reach for this type of coil restorer when routine foaming cleaners have not fully addressed scale, grease, or environmental deposits. At 2.25 pounds per unit, it is compact enough to carry on a service vehicle and appropriate for field use on residential and light commercial equipment.

This restoring solution is suited for use on evaporator coils, condenser coils, and other heat transfer surfaces where heavy contamination has degraded performance. It is typically applied during scheduled maintenance visits or as part of a coil restoration service when a unit is showing reduced capacity or elevated head pressure from fouled surfaces. Proper dilution and dwell time should follow label directions before rinsing.
