Abstract
Aqueous heat transfer apparatus contains a multicomponent corrosion protection system including a first component adapted to release a corrosion inhibitor on exposure to water under relatively milder conditions and a second component adapted to release a corrosion inhibitor on exposure to water under relatively severer conditions. The components may be open top compartments of a capsule, closed by means of covers of controlled release glass which dissolve in water at different rates.
