Limescale is not usually visible to the naked eye in water.
Only when (hard) water is heated can limescale be recognised as a white deposit. But once limescale deposits have formed, it is usually too late. On this page, you will learn how the Fluid Dynamics technology inside the AQON PURE system has been tested for its effectiveness in reducing limescale deposits on surfaces.
Test duration: 18 months [2]
Test object: Six heating elements [3] in an electric domestic hot water generation system [4]
Water hardness: Hard [5]
Test location: Frank E. Moss Federal Courthouse in Salt Lake City, Utah (US) [6]
Carried out by: Oak Ridge National Laboratory (ORNL) and General Services Administration (GSA) in the framework of the GSA Proving Ground Program [6]
The technology prevents calcite deposits and saves energy [8]
In 2012 [4], the General Services Administration commissioned the Oak Ridge National Laboratory to investigate the effectiveness of Fluid Dynamics technology. This Fluid Dynamics technology is built into the AQON PURE system and is responsible for the effect.
The study is based on a before-and-after comparison, which assesses the limescale deposits that form on the heating elements of a water heating system [5].
Before the installation of the catalytic-based technology (Fluid Dynamics technology) and without any kind of water treatment, the commercial heating elements had such a considerable amount of calcite deposits that they overheated and failed after two months of operation. After installation (of the Fluid Dynamics technology), the heating elements showed a small amount of calcite deposits – even after 18 months [12].
The information shown here on the investigation of Fluid Dynamics technology is taken from the original GSA documents. These are available for download here and on the website of the General Services Administration (GSA).
