Impressed current anodes - Modern corrosion protection for your storage tanks
Impressed current anodes are an innovative and reliable solution for protecting hot-water storage tanks and domestic hot- water storage tanks against corrosion. These modern anodes, also known as electrically controlled anodes, replace the classic sacrificial anode, which they have historically replaced. Unlike the sacrificial anode, which sacrifices itself over time and has to be replaced regularly, impressed current anodes are low-maintenance and sustainable as they do not suffer any material loss.
What are impressed current anodes?
Impressed current anodes use electrical voltage to actively ensure corrosion protection inside a storage tank. This technology reliably prevents the formation of rust, and therefore significantly extends the service life of your hot-water storage tank. In contrast to the classic sacrificial anode, which has to be checked and replaced regularly, impressed current anodes remain permanently functional and only require an occasional check of the electronics.
Advantages of using impressed current anodes
Impressed current anodes offer numerous advantages, as they are durable and work efficiently for years, because no sacrificing of the material takes place, they are low-maintenance as no regular replacement is required compared to classic sacrificial anodes, they offer reliable and constant corrosion protection through active control with electrical voltage, and they are cost-saving as the reduced maintenance effort and the longer service life of the storage tank lead to long-term savings.
Possible applications
Impressed current anodes are suitable for most hot-water storage tanks, domestic hot-water storage tanks and heating systems. They can be installed in new storage tanks as well as be retrofitted in existing systems. Especially in regions with hard water, impressed current anodes are a sensible investment to minimise limescale and corrosion damage.
Why impressed current anodes instead of sacrificial anodes?
While sacrificial anodes have to be replaced at some point due to material loss, impressed current anodes work actively and without wear. This makes them a more sustainable and more economical solution for the long-term protection of storage tanks. In addition, there is no need for time-consuming regular maintenance, which makes impressed current anodes particularly advantageous in large systems or storage tanks that are difficult to access.
