A Leading Manufacturer of Low Pressure Watermist Nozzles
Dualmist Ltd is the authorised european manufacturer for DualMIST International Ltd. DualMIST Ltd is a specialist provider of Low Pressure Watermist Systems with a proven and well established range of approved low pressure watermist nozzles. Based in Nottingham, the company operates from close to Junction 25 of the M1. The Components are manufactured to the strictest quality controls and ISO 9001 requirements using Citizen Slidinghead and Nakamura CNC lathes.
Each Nozzle is engraved with a Part Number, assembly date, flow rate and a unique serial number that allows full traceability of all the components back to the raw material certificates. The DM4R and DM4C Nozzles are LPCB Approved and have undergone a vast range of pressure/leak and corrosion testing to eliminate any potential design flaws. Under FPC procedures each nozzles that is produced undertakes a rigourous testing regime (pressure/leak/activation and 100% bulb cull test) to ensure that there are no defects in the product or the bulb prior to dispatch.
The Thermo-bulbs we use are purchased from JoB Gmbh in Germany and are manufactured under ISO 14001.

How It Works
DualMist 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 these smaller droplets as far as possible from the nozzle. In this way we can engulf the entire area in a combination of fine mist and larger water droplets. The larger water droplets have the ability to penetrate the fire and the smaller droplets act like a gas and suffocate the fire whilst also removing large amounts of heat energy. In this way we can easily outperform a conventional sprinkler nozzle using up to 50% less water.
We use Job fast acting bulbs to ensure the nozzle activates as soon as possible
Installation manuals are available. We can also assist you with scheme Design
All nozzle components manufactured from brass or stainless steel.
Lower Flow Requirements
Sometimes water flow to residential houses is too low for conventional sprinkler systems. Dualmist has passed BS8458 fire test with a specially designed nozzle that uses just 25 litres per minute at 7 bar pressure. This makes this technology ideal for such installations.
Lower Installation Costs
Using less water means smaller tanks,smaller pipes, smaller pumps and as some nozzles can be used at 5 metre spacing it can also mean fewer overall nozzles. The end result is that in spite of the nozzle costing more per unit than a sprinkler nozzle, the overall cost of the whole installation can be significantly lower than that of a conventional sprinkler system.
