Components and scope of supply
A system combines a controller, MMO-coated titanium electrode, wiring and suitable mounting parts. Before ordering, confirm which cables, seals, insulating parts and adapters are included. Components must form an approved configuration; matching the thread alone is insufficient.
Before ordering
Provide the manufacturer, exact model, rating plate, tank material, volume and dimensions, anode port, available depth, internal heat exchangers, heating elements, water data and applicable manuals.
* Confirm the exact component references, applicable documentation, price, taxes, delivery and availability for the destination before ordering.
This is a technical guide to electronic titanium-anode systems for hot-water storage tanks. Select the controller and electrode using current documentation for the exact tank: capacity in litres alone does not establish compatibility.
What a complete electronic-anode system normally contains
- potentiostat / electronic controller;
- one or more MMO-coated titanium electrodes;
- electrode and functional tank/cathode cables;
- model-specific insulating parts, seals and mounting hardware;
- an adapter only where the tank and system instructions permit it;
- operating and installation instructions for the exact model.

Product-family context
MAGONTEC publishes multiple CORREX controller and electrode families for hot-water tanks. Published family ranges are useful for orientation, but they are not a universal selection matrix. The exact model manual and selection documentation remain authoritative.

Do not select only by tank volume
Tank volume is only one input. Before choosing a controller or electrode, verify:
- exact tank manufacturer and model;
- enamelled steel, stainless steel or another construction;
- number and type of heat exchangers and heating elements;
- existing anode connection, thread and insertion depth;
- clear internal electrode path;
- electrical continuity and required isolation arrangement;
- water conductivity or manufacturer limits, if available;
- tank instructions and warranty conditions.
Adapter and retrofit compatibility
Common European threads such as G ¾, G 1 and G 1¼ are frequently encountered, but thread size alone does not establish compatibility. Port position, depth, sealing concept, electrical isolation, electrode clearance and internal metalwork also matter.
Compatibility should be stated for an exact tank model or documented manufacturer configuration, not at brand level.
What 2.3 V and 1.9 V mean
Where these values appear in product documentation, they are model-specific nominal controller setpoints or reference values. They are not universal tank potentials and must not be transferred to unrelated ICCP applications.
Maintenance and power
Electronic protection requires electrical power. If the potentiostat is disconnected, impressed-current protection is unavailable. The titanium electrode is non-sacrificial, but the complete system still requires the indicator, cables, connectors, insulation and functional tank connection checks stated by the manufacturer.
Need an exact configuration?
Provide the data-plate photo, exact model, tank material, volume, heat exchangers, anode port/thread and a photo of the connection. If those inputs are missing, the correct result is “insufficient data”, not a guessed product recommendation.
