ANGUS chemistries are proven to be effective when used for high-performance pH control and carbon dioxide (CO2) absorption in steam generation systems. They offer superior ability to absorb dissolved CO2 in feedwater and condensate lines, and rapidly dissociate from CO2 in the deaerator without significant amine loss, improving corrosion control in low- to medium-pressure (<1,200 psi) steam generation systems. With low secondary amine content, they also have a more favorable environmental, health and safety profile compared to other commonly used chemistries, such as morpholine.
ANGUS’ oxygen scavengers provide a cost-effective water treatment solution for corrosion control in a variety of boiler systems without the use of a catalyst. These chemistries are equally effective in both vapor and liquid phases and are compatible with other commonly used water treatment chemicals. Ideal for treatment of steam generation systems operating up to 1,200 psi, ANGUS oxygen scavengers do not contain secondary amines and have successfully replaced hydrazine and sodium erythorbate in these systems.
- Highly effective corrosion control in boiler and condensate lines
- Low / no secondary amines
- Favorable toxicity and flammability profile compared to other commonly used amines
- Helps extend equipment life and reduce operating costs

DID YOU KNOW?
The active ingredient in HYDROGUARD I-15 Oxygen Scavenger (IPHA) reacts much faster with oxygen under certain conditions than do any of the other uncatalyzed oxygen scavengers. In addition, the uncatalyzed HYDROGUARD I-15 reacts just as fast as catalyzed diethylhydroxylamine (DEHA). Because HYDROGUARD I-15 has a favorable distribution ratio and does not require a catalyst, it is equally effective at scavenging oxygen in vapor phase areas as it is in the liquid phase.
