How it works
Water mist puts out fire using physics, not volume. High-pressure water is forced through fine nozzles to create a dense fog that cools the fire and starves it of oxygen — using a fraction of the water a sprinkler would.

The science
A fire needs heat, fuel and oxygen. Water mist takes away two of the three at once.
Systems run at around 80–90 bar, forcing water through specialist nozzles.
That pressure atomises the water into a mist of tiny droplets, roughly 50–150 microns across.
The vast surface area of the mist absorbs heat extremely quickly, dropping the temperature.
As droplets flash to vapour they expand, locally displacing oxygen and smothering the fire.
The fire triangle. Mist works on two sides at once.
Drawn to scale. Split the same water into 50–150 µm droplets and its surface area is 7–20 times greater than as 1 mm drops — which is why mist absorbs heat so quickly.
In a fire
A system that sits unnoticed in the ceiling until the moment it’s needed — then acts on its own, without anyone having to be there.

What makes it different
Same goal as a sprinkler — a very different approach, with far less collateral damage.
A fraction of a sprinkler’s flow means far less damage to the building and its contents.
Mains-fed, so there’s nothing bulky to find space for.
Only nozzles near the fire open — typically at around 57°C — and each releases a fine mist rather than a heavy spray.

The process
A straightforward path from first visit to a certified, maintained system.
01
We assess the building, its risks and its layout to design the right coverage.
02
A system designed and documented to the relevant British Standard.
03
Mains-fed pipework and discreet nozzles, fitted with minimal disruption.
04
Full certification on handover, plus scheduled servicing to keep it right.
On site
Real site photographs, not renders.
Flexible feed hoses are made up and labelled before they go in, so each one runs to its planned nozzle.
Feeds run between the joists to each nozzle position, hidden once the ceiling is closed.
The control panel shows system status at a glance: healthy, fault, isolated, running or service due.
Residential and domestic water mist systems, designed to the standard Scotland’s building standards cite.
Fitted and commissioned by qualified plumbers, backed by 19 years of frontline firefighting.
Design and consultancy for architects, builders and developers.
