The TWT patented Deposit Control System prevents new scale build-up and removes existing scale over a period of time in equipment such as boilers, heat exchanges, ice machines, cooling towers, domestic water systems and other water related products. Scale particles and colloids in the water receive a treatment that causes them to remain suspended and away from the surface of the equipment. The effect of the Triangular Wave System lasts for many days, allowing continuous, effective treatment throughout the water system, when in operation.
