The catalytic alloy core changes the structure of hardness minerals, forming soft crystals that stay suspended instead of bonding to pipework or heat-transfer surfaces.
Magcat
Industrial & commercial scale prevention system
FOR POINT-OF-ENTRY
When scale threatens performance, prevention pays for itself
Protect boilers, chillers, and process systems from limescale and corrosion — without chemicals, power, or maintenance. Designed for the most demanding industrial and commercial applications, Magcat delivers long-term, chemical-free protection that keeps your systems efficient, reliable, and compliant.

The real cost of scale
Scale buildup restricts flow, accelerates corrosion, and reduces heat transfer efficiency
In large-scale heating and cooling systems, just 1 mm of limescale can increase energy use by up to 7%
In hard water areas over 150ppm, unprotected assets can begin to lose efficiency in as little as 6 weeks
Left untreated, it leads to unplanned shutdowns, pressure losses, and higher maintenance costs
In 24/7 operations like hospitals, factories, and process plants, those small efficiency losses compound quickly — costing tens of thousands each year in wasted energy
How Magcat works
As water flows through Magcat, its dual-treatment technology delivers magnetic and catalytic scale prevention in one integrated process.
Catalytic transformation
Magnetic stabilisation
A surrounding magnetic array stabilises these crystals, strengthening the treatment effect even under extreme or variable water conditions.
Scale control & system protection
Together, these processes prevent new scale, gradually reduce existing deposits, and maintain consistent energy performance across potable, processed, recycled, and wastewater streams.
Untreated water
Scale forms as crystals that stick to surfaces and build up as hard deposits
Treated water
Scale forms as crystals that flow freely and do not attach to surfaces

Frequently asked questions
How long does Magcat last?
Magcat has a minimum service life of 25 years and is supplied with a 10-year pro-rata warranty. Many units have operated in the field for decades without replacement or maintenance.
Does it remove hardness from the water?
No – Magcat doesn’t remove calcium or magnesium ions but changes how they behave. The catalytic process prevents them from bonding to surfaces, keeping them suspended so scale can’t form.
Will Magcat reduce existing scale?
Yes. Over time, it gradually dissolves and loosens existing scale deposits, particularly in systems where flow is consistent and temperature is stable.
Does Magcat affect water chemistry or compliance?
No. It doesn’t add or remove any substances, alter pH, or change mineral content, so it maintains full WRAS and Reg 4 compliance.
Can it be used with other treatment systems?
Yes – Magcat can be installed alongside filtration, UV or softening systems if required. It’s completely passive and doesn’t interfere with other processes.
Where should it be installed?
Ideally close to the point of entry or before the plant equipment you want to protect (e.g. boilers, chillers, or heat exchangers). It can be installed horizontally or vertically.
What maintenance does it require?
None. Once installed correctly, Magcat operates continuously without power, calibration, or servicing.
