Navi Chemicals has improved corrosion and scale inhibitors which includes organic and inorganic inhibitors to prevent corrosion and scale in both cooling and heating closed system circulations. Inhibitors makes molecular film between water and surface of the metal to prevent corrosion in the circulation system. To maintain the molecular film inhibitors should present in the system consistently. Navi Chemicals has also improved inhibitors which especially works on an aluminum surfaces.
