Cathodic Protection, Redefined

Decades of experience have resulted in the invention of a proprietary method of generating Cathodic Protection Current. Our patented STOPCOR® technology  provides guaranteed results in preventing galvanic corrosion and protecting your investment.

STOPCOR is a self-contained device with magnesium anode which prevents corrosion in equipment ranging from a British household central heating system to a large scale industrial installation.

Innovative – Easy external application – No water contact means pure drinking water!

Focus on Prevention with a partner you can trust!

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.


Up to 80% saving in repair costs.


External fitting means no contact with drinking water.

Long term

Long term protection guaranteed.


It protects extended surfaces compared to other methods available.


No external power source required.


It provides consistent voltage and amperage throughout its 3 – year lifespan.


Environmentally friendly.


The active nature of the magnesium metal entails naturally generated current, compatible with other metals.

Fields of Application


No, grounding is only taken from the wedging anchor on the wall /concrete floor and it is perfectly efficient.
Proper maintenance check requires the use of a multimeter / voltmeter on 2 VDC scale.
The reading of the voltmeter needs to be 1 volt or higher.
Proper connection is possible at any given metallic point of the existing plumbing network.
STOPCOR has been designed for both indoor and outdoor applications and it is not affected by weather conditions.
