Dew scale softener is designed to soften the scales during cleaning. It increases the penetrating power of caustic soda used for evaporator cleaning. The product assists in penetrating the crystal lattice of the scale particles resulting in softening of even the toughest scale deposits like silicates, sulphates and carbonates normally found on evaporators. The scale is then easily removed with the help of cutters and brushes. Breaking of cutters is minimized and the life of tubes and cleaning equipment is prolonged.
