Dualmist International Ltd is a UK based company that specialises in the Research and Development of Low Pressure Watermist Systems and Nozzles for use in the Fire Suppression Industry.
The DualMIST System uses a variety of methods (impingement, spinners and edge decompression) to create a blend of small and medium water droplet size. We then use larger droplets in the form of jets to distribute the smaller droplets as far as possible from the nozzle. In this way we can engulf the whole area in a combination of fine mist and larger water droplets. The large water droplets have the ability to penetrate the fire and the small droplets act like a gas and suffocate the fire whilst also removing large amounts of heat energy. In this way we can outperform a conventional sprinkler nozzle using up to 50% less water.
Our Misting Nozzles have been through a rigorous regime of independently certified performance testing.
DMI products have a diverse portfolio of fire test accreditations and fire test data that has been overseen and validated by BRE Global. Dualmist International in conjunction with Premier Mist UK Ltd were the first company to attain full fire test approval to the residential published watermist standard BS 8458 and the published BS DD 8489 for commercial watermist systems. In addition to the standard British Standard Protocol. DMI have surpassed the performance of conventional sprinklers at ceiling heights exceeding 5m and have successfully performance tested the DualMIST wall mounted nozzle (DM5) at an extended coverage of 25m2 whilst utilising a water density of only 2mm per m2.
