Limescale- & Corrosion Protection

Aquanode Patented sacrificial anode technology “Made in Germany”

This proven system provides reliable protection against limescale deposits, corrosion, and pitting in piping systems. It operates self-cleaning and chemical-free, making it ideal for drinking water, process, and cooling systems.

With over 100,000 installations worldwide and two decades of field experience, its effectiveness is well established. The technology offers sustainable water treatment without the need for chemicals or intensive maintenance.

It is also suitable for restoring existing pipework, offering a cost-effective alternative to conventional solutions. Particularly in older buildings, this approach can help prevent damage before it occurs.

A study by the German Insurance Association reports that damage caused by corrosion has increased by more than 80% since 1990. One of the main reasons is aging building infrastructure and outdated piping systems.

Without preventative action, property owners face rising repair costs, higher insurance premiums, and eventually, complete system overhauls. This solution offers a practical and economical way to mitigate those risks.

Function and structure

Sacrifical anode sketch of interior construction

The Aquanode from Acquaspar is installed directly in the cold water pipework and reliably protects your system against limescale, corrosion and deposits.

At the heart of the system is a sacrificial anode with a service life of around 6-7 years. On contact with water, a galvanic element is formed that directs corrosion processes specifically to the anode – not to pipes or systems.

Thanks to the integrated chambers, the aquanode cleans itself automatically. The low adhesion tendency due to the Teflon surface also prevents deposits in the filter unit.

The galvanic treatment changes the crystallization behaviour of the hardness formers contained in the water. This results in larger, non-adherent limescale particles that can simply be flushed out – a clear advantage over classic scale.

With the Aquanode, Acquaspar provides a technically mature, low-maintenance and environmentally friendly alternative to chemical water treatments. Ideal for residential, commercial and industrial buildings.
