Izziv
The facility operated 5 computerized, highly efficient natural gas boilers heating approximately 7000 liter of water across seven different loops. Despite continuous adding of expensive boiler corrosion inhibitors, the corrosion rate and herewith the iron content in the water system was never under control. Chemical treatment alone proved insufficient in closed circuits where chemicals have already been consumed on their way to distant parts of the pipe system.
Rešitev Merus
Installation of Merus Rings at the water loops to develop a protective magnetite coating on metal surfaces, removing existing rust and preventing new corrosion formation.
Rezultati
→The iron content reached after a few month time a stable level below 1 ppm, which is far below the set acceptance level of 2.2 ppm. The facility subsequently reduced step by step the dosing of anti corrosion chemicals and now operates with only 1/4 of the corrosion inhibitors used before.
