Technical Specifications – ICCP Active Anode Systems for Water Heaters
System Selection Overview
Selection of the correct ICCP system depends on tank volume, material (enamelled steel or stainless steel), internal geometry, and number of heat exchangers.
All data are for guidance purposes only. The system component recommendations are target values and assume tanks manufactured in compliance with DIN 4753.
Indicative System Selection Guidelines
Selection of potentiostat model, current output and number/length of titanium electrodes depends on tank volume, material, number of heat exchangers and measured protection current demand.
Electrical Specifications
- Protection class: Safety Class II
Electrode Specifications
- Material: Titanium
- Coating: mixed-oxide-coated titanium electrode
- Design: non-sacrificial (no material consumption)

- Multiple electrodes can be used for larger tanks
Potentiostat Specifications
- Function: automatic control of protective current
- Control: setpoint adapted for enamelled and stainless steel tanks
- Measurement: duty cycle operation (millisecond intervals)
- Monitoring: LED status indicator
- Operation:continuous 24/7 operation required
Installation Interfaces
- Sleeve mounting (replacement of magnesium anode)
- Ground connection to tank shell (bare metal contact required)
Operating Conditions
- Suitable for potable water systems
- Compatible with enamelled steel and stainless steel tanks
- Adaptation to varying water conductivity
Standards and Compliance
- DIN 4753-3
Important Technical Notes
- The potentiostat must remain continuously connected to mains power
- Disconnecting power immediately stops corrosion protection
- Correct electrical isolation of the electrode is essential
- System performance depends on correct installation and grounding
- Any additional metallic parts (heat exchangers, heating elements) in enamelled tanks must be properly insulated
Need Exact System Selection?
For precise system configuration, provide:
- Tank volume
- Tank material (enamelled or stainless steel)
- Number of heat exchangers
- Photo of the data plate (type label)
For specified water-heater systems, 2.3 V and 1.9 V are nominal potentiostat setpoints for particular configurations, not universal tank potentials. Actual drive voltage and protective current depend on the model, water conductivity, tank geometry and manufacturer approval.
No scheduled sacrificial-anode replacement is required, but the system is low-maintenance rather than maintenance-free: inspect the LED, cables and connections as specified by the manufacturer. Electricity consumption is low but model- and operating-condition-dependent.
Where stated in the model datasheet, the control unit uses Class II protective insulation. Class II is not an IP enclosure rating.
Adapters are available for common European thread sizes, but compatibility must be verified for the exact tank model, port, internal geometry and manufacturer instructions. The functional tank/cathode connection is distinct from the appliance protective-earth (PE) conductor.
DIN 4753-3 is relevant to corrosion protection of enamelled hot-water storage tanks, but compliance and system sizing must be confirmed for the exact tank/anode combination. Tank volume alone is not sufficient for selection.
Voltage, current, electrode length, temperature, pressure, enclosure rating and power-consumption values must be taken from the datasheet of the exact product; generic values are not binding.
