Cortec S-7 Oxygen Scavenger

Product Description

S-7 is a non-catalyzed sodium-sulfite-based oxygen scavenger designed to protect low- to medium-pressure boiler systems against corrosion during normal operations. Oxygen present in feedwater can cause severe damage to boiler equipment if left unchecked (e.g., pitting corrosion on the metal surface can result in rapid failure of the boiler). Ten parts of S-7 are necessary to remove one part oxygen. S-7 is not recommended for use in high-pressure boilers. S-7 can be used for the removal of OCl- from cooling water or wastewater where the presence of chlorine is restricted

Packaging and Storage

S-7 is available in 5 pound (2.3 kg), 50 pound (23 kg), and 100 pound (45 kg) drums.

To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F (4- 38 °C).
