Closed Loop Systems

A closed loop system encompasses the chill water and hot water systems. The majority of our products are liquid concentrates for ease of addition. Formulations cover pure water loops to high hardness, high alkalinity water systems. High makeup (high leakage or water use) systems require the consulting of your service representative as you should with any water treatment question.
