Water Storage

Fire Protection Misting Tanks


Tricel Killarney provide storage solutions for misting tanks. Misting systems are a fixed fire protection system which uses water droplets to control, suppress and extinguish fires.



How it Works

A misting system uses nozzles which are fitted to a water piping system connected to the water storage tank. Once activated, the water is pumped from the misting water storage tank to the automatic nozzles. The nozzles automatically discharge fine water droplets or water mist, which fills the protected zone removing two of the three elements for a fire to spread. Elements removed include, oxygen & heat. This type of fire protection would generally be installed with smoke alarms or fire detection systems.

Fire protection misting tanks are extremely effective and significantly reduce asset damage and operational downtime in all business-critical applications.The larger the surface area, the more effective the system becomes in quickly reducing temperature and oxygen at the flame front.

The main objective for installing a water mist system:

  • Fire Extinguishment. A sharp reduction in heat release rate leading to complete elimination of any flaming or smouldering fire or
  • Fire suppression/control. A steady reduction in the heat release rate resulting in a lower controlled level of burning/limitation of fire growth and protection of structure (by cooling of the objects, fire gases and/or by pre-wetting adjacent combustibles)


The benefits of using water mist fire suppression in comparison to more traditional sprinkler systems, are as follows:

  • Immediate activation
  • Quicker fire fighting due to its cooling properties (water into steam)
  • Minimized water damage due to the low consumption of water required for the system
  • Less downtime to businesses resulting in lower costs
  • An environmentally friendly solution to fire suppression
  • The mist can extinguish a fire in shielded and obstructed locations

Water tank options for misting systems


  • Insulated – suitable for storage of wholesome water
  • Un-insulated for storing of water for non-wholesome applications

Examples of applications for misting systems:


  • Data centres
  • Hotels & residential buildings
  • Commercial Offices & Banks
  • Hospitals, Community& Care Centres
  • Schools & Universities
  • Museums and archiving centres

Misting tanks performance & regulations



The appropriate minimum duration of water supply needs to be selected for each project as it is currently not a prescribed standardised value. Values of minimum duration of water supply could be taken as for automatic sprinkler systems, for similar premises, e.g. minimum durations for:

  • Domestic – in excess of 10 minutes for BS 92515 sprinkler systems
  • Residential – 30 minutes for BS 92515 sprinkler systems or in excess of 60 minutes for BS EN 128453 or BS 5306 Part 24 sprinkler systems.

To ensure optimum performance and compliance with regulations, the following ancillary items are usually fitted to our fire protection tanks:

  • Hydrostatic contents gauge to measure the level of water in the tank.
  • AB Air gap to prevent water siphoning back into the mains water supply.
  • Internal Ladder for safe tank access.
  • External aluminium ladder complete with safety cage to safely gain access to the man-way cover for maintenance purposes.
  • Tank overflow and warning pipes.
  • Drainage facility to completely drain down the tank for maintenance work.
  • Access man-way to enable testing, maintenance etc.
  • Side access hatch.
  • Vortex inhibitor eliminates air circulation through the water when large volumes of water are extracted from the tank.
  • Immersion heater to prevent water from freezing in the tank and pipe work.
