What causes Electrochemical corrosion?
Electrolysis is a naturally occurring phenomenon resulting in the corrosion of metal surfaces.
Electrochemical corrosion (electrolysis) is brought about by the flow of ions from negatively charged metals to positively charged metals when they are connected in the same environment. The resulting electromotive force appears as voltage. This voltage is proportional to the flow of the aforementioned ions and its increase directly affects the intensity of the electrolysis phenomenon.
The naturally occurring phenomenon of electrolysis manifests itself in metal structures, bridges, storage tanks and generally in plumbing installations, machinery, engines etc.
STOPCOR Reduces Limescale
The generated impressed current of the STOPCOR devices creates a magnetic field, thereby activating the Brownian movement in liquids.
The Brownian movement is the random movement of particles.
This process prevents the damaging effects of limescale accumulation in plumbing equipment.

Key Features
The STOPCOR anode product line utilizes the method of producing and imposing impressed current through a sacrificial magnesium anode which creates an electrolytic dipole capable of generating voltage of up to 1,5 volt and current density of up to 10mA when present in a standard environment.
Fields of Application
Commercial Applications
The innate complexity of large scale commercial piping networks represents an entirely different challenge for the engineers.
Marine Applications
Boat engines, air conditioning, metallic installations, engine components
