The MistTech system, using unique collision-drop technology, provides a more consistent droplet size for higher efficiency mist. It is a highly effective, lightweight and flexible firefighting solution for use in the Primetech MultiPod® carried on smaller, lower emissions and utility-style vehicles.
Primetech has launched its ground breaking new MistTech range, specially designed for rapid intervention vehicles, whether low emissions electric vehicles or lower emissions vehicles such as as utility vehicles carrying the Primetech MultiPod®. What makes the MistTech system unique is the way that it uses the patented collision-drop system to produce fine mist at the branch or nozzle head.
This method gives firefighters the advantage of a cooler working area close to a fire, and improved fire suppression capabilities. This is achieved by two jets of water coming out of the branch or nozzle head and colliding at carefully calibrated angles resulting in a highly efficient mist droplet firefighting capability.
At a recent demonstration at a Fire and Rescue Service training centre, observers were impressed by a live demonstration of the MistTech system. The rapid fire suppression effects were demonstrated on both a car fire and a domestic structural fire scenario, using lower than normal levels of water. This is due to more effective firefighting power of mist.
What makes the MistTech system unique is the way that it uses the patented collision-drop system to produce fine mist at the branch or nozzle head. This is achieved by two jets of water coming out of the branch or nozzle head and colliding at carefully calibrated angles resulting in a highly efficient mist droplet firefighting capability.
Primetech’s Sales Manager, former firefighter Wayne Porter, explains further: ‘Unlike other systems, MistTech is designed with numerous pairs of holes, which are strategically located around the entire length of the branch or lance. These holes are designed to create two streams of water at low pressure, which collide with each other and break apart. Water droplets are created, at that point.
‘This technology uses low pressure but acts in a high-pressure capacity. The angles and size of these holes is very important, as it is this design that produces its unique misting quality’.
The MistTech system is highly versatile and can be adjusted according to the type of misting environment required for the specific fire scenario being encountered. It will deliver water as droplets at a maximum flow of up to 130/140 litres per minute (in jet mode), but the system will also operate at much lower pressures if required. The larger the droplets the bigger the surface area and distance covered; the smaller they are the greater the surface area cooling effect, but with a lesser ‘reach’, and thus taking the heat out of the fire more quickly. In addition, the water droplet mist forms directly at the end of the branch, which provides a protection heat barrier for the firefighter against the fire.
The branch head has dual functionality in that it can operate in a traditional manner, by producing a firefighting jet, or produce the revolutionary misting effect by a twist of the branch.
The system has been designed so that the QR Quick Release version of the MistTech branch allows firefighters to convert quickly and easily between the branch spray option and the lance option, depending on operational requirements.
With a swift bayonet release movement, misting system branches can be simply swapped at the end, meaning that with one body on the vehicle, the system can operate several different pieces of equipment, used at different stages during firefighting. In addition, there is an option for an attachment to deal with chimney fires and fires within confined spaces. Engine-powered and electric-powered versions are both available.
The equipment can use both water and foam. Misting /CAFS fire fighting equipment can operate as a misting system only, producing high efficiency water mist, or switched over to foam, if required, which produces CAFS. With the MistTech range of firefighting systems the water turns to steam, therefore there is less entrained air and the user has greater thermal protection. There is minimal collateral damage and no flooding risk. In short, misting is a high efficiency method for combating fires that uses minimum amounts of water and foam to deliver positive firefighting outcomes.
Primetech believes that in many circumstances this is the way forward in the future of firefighting and is a sound solution where water supply is limited, such as in remote areas of the UK. Because the system can be carried din smaller, lighter weight vehicles, it also supports the goal of creating lower emissions fleets to helps fire services and central and local government greener cities objectives – lower pollution and lower carbon emissions.
In practical terms, the move to faster, more varied fleets of emergency response vehicles means that different types of vehicles will be sourced for different types of incidents. Primetech can offer a solution to utilise dormant vehicles more precisely, effectively and in a more versatile manner. These can be deployed to different types of fires and for other, more collaborative, multi-agency roles.
Even when larger appliances are required, rapid intervention vehicles can travel faster - sometimes getting past traffic congestion along the way - and arrive earlier to start tackling fires in advance of the arrival of the larger vehicles in the fleet. Speed of attack, initial firefighting power and agility are the key to successful firefighting.
Firefighting effectiveness is a prime consideration with this new approach to rapid intervention response. The equipment carried on rapid response vehicles need to be capable of delivering the kind of high-powered fire suppression capability, which can have a decisive early effect, delivering the initial ‘stop-the-clock’ impact required.
Primetech have a proven solution for portable firefighting. MistTech is a high spec Misting System which can be installed in the latest upgraded version of the Primetech MultiPod®.
Primetech’s upgraded MultiPod® system is a unique lightweight demountable body system for use on utility vehicles for which no vehicle modifications are required. It can be easily and quickly mounted on any standard utility vehicle, giving Fire and Rescue Services a lower cost option for deploying to incidents quickly. MultiPod® is capable of being carried on sub 3.5 tonne utility vehicles, such as the Ford Ranger, Isuzu DMAX and Toyota HiLux. The new upgraded version of the Primetech MultiPod® is 10% lighter and stronger than the previous version, while still retaining all the storage flexibility of the MultiPod® format. MistTech systems can also be supplied without the MultiPod®.
MistTech misting system together with CAFS (Compressed Air Foam System) provides misting and foam-based fire fighting capability where the full power high pressure/aggregate lance-based system is not required.
In both cases, the power of water mist delivers the fire suppressing power. It is well documented that water mist is the only method in the world to extinguish most classes of fire using only water and no additives, ensuring a truly environmentally friendly solution.
The system has been generating high levels of interest because it supports the drive for lighter, faster, lower emissions and more flexible approaches and fleets, and increased levels of collaboration between the emergency services. It also helps to improve public safety in an era of tighter budgets, and supports the drive for diversified, expanded and more effective use of service resources.
To provide Fire and Rescue Services with reassurance, Primetech are ISO 9001 certified, therefore quality assurance is guaranteed.
