Abstract
A filled insoluble polymer containing one or more corrosion inhibitors and a slightly water soluble polymer is utilized to automatically and continuously add a corrosion inhibitor to a coolant solution passing through a heat exchanger. The corrosion inhibitor is gradually leached from the filled polymer supplying inhibitor to the coolant to protect the metallic parts of the coolant system that are subject to corrosive conditions.
