CONRROLLED REALEASE COOLING ADDITIVE COMPOSITION

摘要

A controlled-release additive composition for use in aqueous systems. The composition comprises a core containing at least one additive component and a polymeric coating encapsulating said core. The controlled released cooling additive composition slowly releases the additive components to aqueous system, thereby delivering an effective concentration level of additive components over an extended period. A liquid replacement system is provided for introducing additivies to an open recirculating system or a closed loop boiler water system in a controlled manner. The liquid replacement system comprises a make-up line and an additive system disposed therein. A make-up liquid enters into the make-up line where the additive system is structured to provide a controlled release of an additive to the make-up liquid, and the make-up liquid carries the additives into the open recirculating system or a closed loop boiler water system. The liquid replacement system allows for controlled release of additive components to the open recirculating system or the closed loop boiler water system, thereby delivering an effective concentration of additive components over an extended period.
