Preventing the generation of chiller scale should be controlled from the source to maximize the system's good operation and reduce losses, such as installation (Oerivo) automatic self-cleaning water filter. In addition, it is also possible to use an electronic descaler, such as the Dekore electronic descaler, which uses a combination of electric waves to change the physical structure of calcium and magnesium ions in water, and becomes a new crystal insoluble in water, which will suspend. In the water, it will not adhere to the pipe wall to prevent scale formation. Since calcium and magnesium ions are precipitated from the water, the water returns to a high dissolved state. The water itself is a highly soluble liquid, but it is saturated by absorbing other substances. When the water that returns to a high dissolved state flows through the scaled pipe, it can The scale dissolves and absorbs and is drained when drained. Therefore, in addition to preventing scale formation, the product can effectively remove old scale.
