Water Mist Guardian System

Small yet powerful, the target nozzle will emit a fine 360o water mist directly towards any fire below at an operating pressure of 80-90 Bar. Bridging form and function, the aluminum misting nozzles are manufactured using an electrolytic passivation process to resist wear and erosion, while an electrostatic applied polymer finish adds an elegant final touch. Measuring 62 mm in diameter and a mere 30 mm in depth the mist heads are sleek and discreet.

British Design Engineering

The Guardian nozzle is carefully machined within the UK and tested in-house to the highest standards to ensure full system integrity in normal settings, and full performance ability should it ever need to run in a fire scenario. Slightly larger than a standard GU10 LED light fitting, it is highly discreet and once installed is very difficult to notice daily. This can be enhanced with a unique production point that allows us to colour match the nozzle at production stage to the colour of your room.

Tried and tested

Our Guardian pump set is the result of many tests, performance reviews and development meetings, and is wholly owned by SmartMist Systems. This gives us greater control over the production and development of the system, which in real terms means you, our customer, is receiving the best time, attention and care possible.

Simple to use

The Guardian system can be installed into a wide range of properties, and in over 95% of properties it can be connected directly into the mains water supply and the existing electrical distribution board. Water requirements are very low, so no large changes are required to the incoming supply, and no large water storage tanks or booster pumps are required. Small bore, flexible pipework allows for quick, simple installation both in early stage first fix projects and in retrofitting projects.
