Unlike traditional scavengers, it not only removes oxygen from the feed-water but also forms a protective organic compound on boiler steel surfaces. Its filming properties are especially effective during shutdown periods, protecting lines where moisture and oxygen are present.<\/p>\n<hr data-path-to-node=\"8\" \/>\n<h3 data-path-to-node=\"9\"><span class=\"ez-toc-section\" id=\"APPLICATIONS\"><\/span><b data-path-to-node=\"9\" data-index-in-node=\"0\">APPLICATIONS<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p data-path-to-node=\"10\">Used for comprehensive control of corrosion throughout feed-water, steam lines, and condensate systems.
