Sodium Nitrite

DESCRIPTION: AQL CL 333 is a liquid blend of sodium nitrite, sodium borate, yellow metal inhibitor and a dispersant. AQL CL 333 is a non-chromate inhibitor, specially formulated for corrosion in copper, steel and multi-metal systems, whether they are airtight or not.
APPLICATION: AQL CL 333 is a corrosion inhibitor for use in chilled-water closed loops, hot-water recirculating boilers, and above-ground thermal storage systems. This product provides effective corrosion protection for metals typically found in closed-loop systems. In addition, AQL CL 333 contains a borate buffer to maintain pH of the recirculating water in the range of 8.5 to 10.5.
PRODUCT DOSAGE: The initial dosage of AQL CL 333 is 1 liter for each 1000 liters of water in the system (1100ppm). This will provide a sodium nitrite residual of 275 ppm as NaNO2.
