 Material Safety Data Sheet



DRY INHIBITED SULFAMIC ACID CLEANER FOR GALVANIZED STEEL COOLING TOWERS


DESCRIPTION:

ALKEN® DRSD 887 is an effectively inhibited dry acid blend with corrosion inhibitors and wetting agents designed for cleaning galvanized heat transfer surfaces in cooling towers. ALKEN® DRSD 887 can be used to clean a cooling water system while in operation. ALKEN® DRSD 887 incorporates patented inhibition technology, for a high degree of electrolytically restrained action to the attack by acids on base steel, while ensuring high efficiency descaling, rinsability and fume reduction.

DOSAGE DIRECTIONS:

The dosage of ALKEN® DRSD 887 performs optimally when heated to 95 F or above. For cleaning, maintain a solution of 40 to 80 lbs of ALKEN® DRSD 887 per 100 gallons of water in the system. To measure pH, boiling point and freezing point, the most common dilution of 9% (0.8 lbs. ALKEN® DRSD 887 added to 1 gallon cool water) used for system cleaning was used. If oil and grease deposits are also detected, pre-clean the system with ALKEN® CW 883 for optimum system performance.

ALKEN ALKEN® DRSD 887 is an acid product and its solutions are strongly acidic. Do not take intermally. Avoid eye and skin contact. Should contact occur, immediately flush area with large amounts of water. Strict adherence to the safety procedures prescribed, especially those in the Material Safety Data Sheet, is necessary in order to handle and use this product safely
