As France accelerates its energy transition, ADEY, a pioneer in magnetic filtration, emphasizes a fundamental principle: the performance of a heating or air conditioning system depends primarily on the quality of the water circulating within it. We spoke with Stéphane Kling, France Country Manager at ADEY.
In the collective imagination, energy renovation mainly involves insulating attics or replacing aging boilers. However, there is an invisible menace silently threatening the efficiency of millions of installations across the country: sludge build-up. This phenomenon, caused by the accumulation of magnetite and bacterial residues, clogs the networks, causes premature breakdowns, and significantly increases the energy bills of households and businesses.
Since the invention of the first magnetic filter MagnaClean by the British engineer Chris Adey in 2003, ADEY has established itself as the undisputed leader in its sector. Present in about thirty countries, ADEY uses cutting-edge engineering to protect central heating and air conditioning systems.
This British technology now equips large real estate complexes, from individual residences to institutional buildings like hospitals. Its reliability is such that it has been chosen to equip demanding environments such as the French submarine fleet, where the continuous operation of HVAC systems is a vital necessity.
The issue of filtration goes beyond mere mechanical maintenance to become a cornerstone of the environmental strategy of buildings. An untreated network can lead to a 27% increase in energy consumption, a waste that ADEY’s powerful magnets can immediately counteract.
By optimizing thermal efficiency, the company not only reduces operational costs but also actively contributes to lowering carbon emissions. This commitment to the planet has been part of the group’s DNA since 2007 when it achieved carbon neutrality.
For modern installations like heat pumps, highly sensitive to impurities, this magnetic protection has become an essential guarantee of their durability and efficiency.
To ensure optimal thermal comfort, ADEY offers a complete ecosystem that enables professionals in the sector to provide a comprehensive response to their clients. This approach relies on essential synergy between the power of magnetic filtration and the effectiveness of chemical treatment solutions. By following stringent protocols (water analysis, curative cleaning, and preventive protection), technicians have powerful tools to transform a simple intervention into a genuine advisory and sustainability mission.
Although the 2020 regulations now require sludge verification, it is through this combined expertise that technicians can highlight their skills.
By making the invisible visible to end-users, ADEY helps professionals demonstrate that fluid maintenance is as strategic for budget control as equipment maintenance itself. This blend of technological innovation and educational efforts now defines the standards for modern and sustainable thermal maintenance.
