AQL CL 333TM - CLOSED-LOOP CORROSION INHIBITOR

Benefits:

  • Provide corrosion protection in the piping of thermal storage units and large Closed loops.
  • Prevents exchangers and zone valves from plugging due to corrosion.
  • Reduces corrosion damage to water pump impellers and seals.
  • Non-chromate formula contains no heavy metals.

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.
The maintenance dosage is 1 gallon of AQL CL 333 for each 1000 gallons of makeup water added to the system.  The sodium nitrite level should be maintained in the range of 250ppm to 400ppm.  The pH of the recirculating water should be in the range of 8.5 to 10.5. Do not allow the pH to drop below 8.0
 
METHOD OF FEED: Feed AQL CL 333 to the closed-loop system using a by-pass pot feeder. For above-ground thermal storage systems, add the product at the time the system is initially charged with water.

WARNING

CAUSES SKIN IRRITATION AND ALLERGIC SKIN REACTION

CAUSES SEVERE EYE IRRITATION

MAY CAUSE IRRITATION IF INHALED

HARMFUL IF SWALLOWED

Contains Sodium Metasilicate and Sodium Nitrite.  Avoid contact with skin, eyes and clothing.  Wear neoprene rubber gloves if repeated or prolonged skin contact is likely.  Wear safety glasses if the method of application presents the likelihood of eye contact.  Avoid breathing the mist.  Use sufficient ventilation to prevent the buildup of mist.  Wash thoroughly after handling.  Swallowing may cause gastrointestinal irritation seen as nausea, vomiting and diarrhea.

FIRST AID:

FOR SKIN CONTACT: Wash affected areas with plenty of soap and water for 15 minutes.  Remove contaminated clothing and shoes.  Get medical attention.  Wash clothing and clean shoes before use. FOR EYE CONTACT: Rinse the eyes with water.  Remove any contact lenses and continue flushing with plenty of water for 15 minutes.  Hold the eyelids apart to ensure rinsing of the entire surface of the eyes and lids with water. Get immediate medical attention.  IF INHALED: Remove from the area to fresh air.  Seek medical attention if respiratory irritation develops, or if breathing becomes difficult.  IF SWALLOWED: Immediately give 3 to 4 glasses of water and induce vomiting by placing a finger or blunt object on the back of the victim’s tongue.  Give fluids until the vomitus is clear. Get immediate medical attention. DO NOT induce vomiting or give anything by mouth to an unconscious or convulsing person.
