Cotto Tiles faced a complex cooling system challenge where both scale and oil contamination made treatment difficult.

As part of the Thai Cement group, the plant relies on mould machines cooled by a recirculating water system. The circuit suffered from silica and calcium deposits, made worse by heavy oil contamination. Various chemical and non-chemical treatments had been tried previously, but none were successful.

A Magcat water conditioner was installed on the cooling circuit, sized to manage the full system flow and target both new and existing scale.

After six months, the results showed:

Scale deposition stopped completely.
70% of existing scale was removed.
Cooling efficiency improved across the machines.
Energy and maintenance costs were lowered.
Continuous protection was achieved without the need for chemicals.
This case highlights how Magcat performs in demanding ceramics manufacturing environments where conventional methods fail.

How does catalytic water conditioning actually work? It comes down to changing how minerals behave in the water.

Fluid Dynamics technology doesn’t remove calcium. It changes its structure so it can’t form hard scale.

The process is simple—but highly engineered:

1. Water passes through the treatment chamber
Inside the unit, water flows over a patented catalytic core designed to create turbulence and trigger a reaction.

2. The mineral structure is altered
Calcium carbonate crystals are transformed so they stay suspended in the water rather than bonding to surfaces.

3. Scale can’t form
With no adhesion, limescale doesn’t build up. Systems stay clean, efficient, and protected.

This means:

• No chemicals or salt
• No power required
• No regeneration cycles
• No routine maintenance

It’s a different way of treating water—one that works with the chemistry, not against it.

We don't outsource what matters.

Every Fluid Dynamics core technology is designed, engineered, and assembled in the UK - because when you're building water treatment systems, quality isn't negotiable.

In-house manufacturing gives
→ Complete control over design and performance
→ Traceable, consistent build quality
→ Faster iteration and improvement
→ End-to-end accountability

50+ years of British engineering expertise. Not a legacy. A competitive edge.

Addressing scale at Daimler Truck with Magcat.

The cooling system at this facility was struggling with persistent scale build-up. This was causing poor heat transfer and higher maintenance requirements, which directly impact the bottom line through increased energy consumption and operational downtime.

To solve this, a Magcat unit was installed to control calcium carbonate formation throughout the system.

The results following installation included:

Controlled scale accumulation.
Restored heat exchange efficiency.
Reduced frequency of manual cleaning and maintenance.
Consistent, more reliable equipment operation.
This case shows a straightforward approach to a common industrial water problem.

Hard water. Severe scaling. Constant maintenance.

When limescale builds up, it drives energy costs, reduces efficiency, and shortens equipment life. The impact is real—and expensive.

This is what happens when that cycle is broken.

Our catalytic water conditioning technology changes how scale forms, keeping systems clean without chemicals, salt, or ongoing maintenance. The result? Lower operating costs, improved performance, and long-term protection across your system.

Real results. Real impact.
