THE ADVANTAGES OF THE DUALMIST SYSTEM
There are many advantages of using the dualmist system over a traditional sprinkler system, these are described below:
Larger Coverage per Nozzle
Our nozzles have passed tests that cover a much larger area per nozzle than a traditional sprinkler. This considerably reduces the amount of labour required to fit out a room. The overall amount of nozzles and pipe required is also reduced.
Higher Working Pressure
There are several advantages of having a slightly higher working pressure than a standard sprinkler system.
As with sprinklers, the system still can use CPVC pipe so it can be quickly installed but the extra bit of pressure
means that you can go further up in height without the need for additional pumps. A larger working pressure range allows a single pump system to cover many floors.
Higher K- Factor
The watermist nozzle is more restricted than a sprinkler. If a nozzle activates then the pressure drop to subsequent nozzles is not as significant and this enables longer spurs and in general fewer/smaller pipes to be used.
We have also found that another selling point is that we can also provide a blow off cap (available in black or white) to fit over and fully protect the nozzle head which means the nozzle can sit discreetly and inconspicuously in any ceiling. This makes it ideal for hotels and offices and similar situations where the aesthetics are important.
Less Water Damage
Using 50% less water means any damage caused by the water is reduced.
Smaller Tank Saves Space
In many major cities, space is expensive and a smaller tank is highly preferable to the huge tanks needed by sprinkler systems.
Higher Overall Performance
Due to the fact that the nozzle is producing a range of droplet sizes this means multiple methods are simultaneously being used to suppress the fire.
Dualmist inhibits both pyrolysis and oxidation - not just one of these - see 'how it works'
Highly Competitive Overall System Cost
The overall costs of a fully approved Dualmist low pressure system is often lower than that of a comparative sprinkler system. The reasons for this are sometimes subtle. It has to do with many factors including the higher K-factor, lower flow and wider spray coverage of the various nozzles which allows systems to be designed with fewer nozzles , smaller pipes and smaller pumps and tanks.
The combination of all these factors means if the system is designed correctly then advantageous pricing can often be achieved over rival systems. When you combine this with the fact that the suppression ability of the Dualmist System is far greater than that of a sprinkler system (see 'how it works') then you can begin to understand why companies using the Dualmist System as an additional offering can rapidly gain market share from companies only offering sprinkler systems alone.
