New Electrolytic Anti-Scale Solution from Altecnic: Caleffi eCAL®

Chemical-free, low-energy solution offers sustainable limescale prevention for domestic and commercial heating systems

Altecnic have launched the Caleffi eCAL®, an innovative electrolytic anti-scale device designed to combat one of the most persistent challenges facing British heating systems: limescale caused by hard water.

Limescale buildup affects millions of homes and commercial systems across hard water regions of the UK, leading to reduced system efficiency, higher energy bills, and costly maintenance. The Caleffi eCAL® offers a smart, sustainable, and maintenance-free alternative to chemical water softeners and traditional magnetic filters.

How does the Caleffi eCAL® work?

The Caleffi eCAL® is an inline electrolytic treatment device that prevents limescale formation without altering water chemistry. It works by using a low-voltage electric field to convert calcium and magnesium ions into stable aragonite microcrystals, which remain suspended in the flow and are flushed out naturally, rather than forming scale on heating elements and pipework.

An integrated stainless steel filter (50 μm) captures suspended particles, while a high-performance neodymium magnet traps ferromagnetic impurities, delivering dual protection for potable systems.

A self-contained system with no moving parts, the eCAL® reduces installation time and eliminates the need for regular servicing, with a 7-year average internal cartridge lifespan. With installers in mind, the Caleffi eCAL® has been engineered to be as intuitive and efficient to install as it is to operate, with Transparent filter chamber for clear visual inspection. Cleaning and maintenance is also made easier for the installer with tool free cleaning with a removable cartridge and isolated magnet chamber for straightforward maintenance.

Gary Perry, Managing Director at Altecnic, commented, ‘With the UK’s push toward low-carbon heating and greater system efficiency, the Caleffi eCAL® arrives at the perfect time. Installers and specifiers need reliable, sustainable ways to protect modern heating systems without introducing chemicals or costly maintenance. eCAL® delivers all that in a compact, plug-and-play format’

 

The Caleffi eCAL® will be on display for the first time in the UK on stand 5D15 at the InstallerSHOW from 24th-26th June 2025.
