NARC™
Non-Acid Rust Cleaner
Non-acid Rust Cleaner for Closed Water Systems
Rust and iron oxide buildup in closed heating and cooling systems reduces heat transfer efficiency and raises operating costs, NARC™ removes it without using acid. Its formula loosens and lifts rust deposits from closed systems, heat exchangers, compressors and piping. It cleans without requiring neutralization, helping maintain clean, efficient system operation. Safe for steel, copper, brass, and plastic piping.
Where to Use NARC™ in Closed Loop Systems
Use In: closed loop heating and cooling systems, heat exchangers, steam boilers, compressors, and piping.
Recommended For: hospitals, schools, warehouses, and industrial facilities operating hydronic heating or steam boiler systems.
Effective Against: rust, iron oxide, magnetite deposits, scale, and calcium buildup in closed loop water systems.
On-Line cleaning of closed heating and cooling system:
Add NARC™ at a rate of 1 gallon per 200 gallons of system water in the closed loop system. Allow to circulate for 24 hours and then bleed 10% of the closed loop water. Add back an additional 1 gallon of product for every 200 gallons of fresh water added to maintain product concentration. Repeat this process for 5 – 7 days then drain and flush the closed loop to remove excess dispersed iron and scale. Fill the closed loop system to operating volume. Add sufficient State Industrial Products corrosion inhibitor treatment. Return system to operation.
During any on-line cleaning process small leaks may occur. Be prepared for water leakage. During the cleaning process rust and scale will be removed as fine particles. System filters may become plugged with these fine particles and may require service frequently during the cleaning process. As an added benefit consider the installation of State Chemical Filter Feeder. The Filter Feeder makes a convenient location to add chemical treatment as well as remove iron or other fine particles from the closed loop water.
Steam Boiler Water additive:
For additional scale and iron control in steam boilers, add 1 gallon of NARC™ to 55 gallons of State Chemical scale and corrosion inhibitor. NARC™ is not compatible with State Chemical Superhot™ Complete or Superhot™ NST. NARC™ is not NSF certified for use in steam boilers where steam may contact food. Please review label and SDS for all product directions, precautions, and first aid information.
