Realize real cost savings with Chemetall descaling products and solutions
Nozzle and pipe descaling
Maximize your spray efficiency
- Scale, soils, and particles deposit on the inside of the nozzle and restrict flow uniformity from the nozzle.
- These photos compare the spray pattern of a clogged nozzle versus an unclogged nozzle.
- Cross section of a pipe before and after descaling.
Heat exchanger descaling
Maximize your heat exchanger efficiency
- Scale forms when water salts in the solution settle and plate on the outside of the heater tube.
- The scale builds and becomes thicker over time and acts as an insulator, preventing the heat from the heater tube from reaching the solution.
- Scale build up leads to a higher usage of natural gas.
How scale can affect cost efficiency
A washer with an 1/8 of an inch of scale on the heater tube could cost an additional $50,000 per year for gas.
Effective descaling may save up to $12,500 per year for gas.
