“LOTUS FIRE PROTECTION“ Ltd. is a newly established company with the aim to offer a state-of- the-art fire extinguishing system. Four successful companies united their knowledge and experience to create a reliable partner who is able to design and execute a complete “turn-key” system.
WATER MIST SYSTEM
SMART USE OF WATER
For a fire to survive, it relies on the presence of the three elements of the ‘fire triangle’: oxygen, heat and combustible material. The removal of any one of these elements will extinguish a fire.
The high-pressure water mist system goes further. It attacks two elements of the fire triangle: oxygen and heat. The uniqueness of high-pressure water mist is that it combines the suppression effect of gas and sprinkler systems. As well as removing the oxygen like a gas, a gas system simultaneously cools the fire like a traditional sprinkler. The cooling effect additionally lowers the risk of re-ignition.
LESS WATER CONSUMPTION,
WATER DAMAGES & MINIMUM DOWNTIME
Very fine particles of water mist have a size of 50-100 μm so that they can quickly penetrate the fire and in that contact, they quickly evaporate spreading through the space thus cooling the fire and at the same time removing oxygen from the space. There is reduced water consumption and no need for a large water supply reservoir. The size of the water supply reservoir is up to 66% smaller than with a conventional sprinkler system.
In case of a fire, there is little water damage to furniture and equipment. The clean-up is easier with no business interruption and, consequently, lower risk of losing market shares and lower insurance costs.
SIMPLICITY & FLEXIBILITY IN INSTALLATION
Installation of the highest quality stainless steel is minimally invasive for installation in older as well as in new facilities. The pipeline is extremely light, including the water in the pipeline it is 85% lighter than traditional sprinkler systems.
The modular design of the system provides flexibility for future extensions to cover more protected areas.
LOWER COSTS FOR MAINTEnance
All key components of the high-pressure water mist systems are high-quality components.
High-pressure pumps are multi-axial piston pumps made from stainless steel. Water is used as a lubricant, making the pumps virtually maintenance free.
The piping network, nozzles and section valves are also made from stainless steel. This ensures a long service life for the system installed.
TESTED AND APPROVED
The design of the high-pressure water mist system is based on full scale fire tests. For industrial and commercial applications, approvals are obtained through testing in accordance with specifications from, for example FM, UL, ISO and NFPA standards, as well as from the European guideline CEN/TS 14972 and approvals from DBI and VdS
Internal HSE&Q system in accordance with:
– DS/EN ISO 9001:2015
– DS/EN ISO 14001:2015
– DS/OHSAS 18001:2008
Using high-pressure water mist keeps secondary damage to a minimum due to the low water consumption. Water coming from the pipes is clean water as system uses stainless steel pipes that are corrosion resistant. In case of system release, the clean-up is easier, faster and incurs lower costs. In addition, the system is only activated in areas where fire is detected. Other areas in the building will not be affected.
BEST CHOICE FOR WINDOW COOLING
The excellent cooling features of the high-pressure water mist system make it the perfect choice for protecting glass facades. The system has passed EN-1364-1 fire resistance test for nonloadbearing elements. Instead of spraying water on the glass, the system atomises the water in front of the glass. This threedimensional cooling removes the risk of thermal stress cracks associated with traditional water-based sprinkler systems, and allows the use of a cheaper class of glass. This means significant savings for the building investors.
SAFE FOR PEOPLE
The high-pressure water mist system for fire-fighting helps with controlling of heat, smoke and toxic gas. This is great advantage when it comes to the safe evacuation of the occupants. Also, it can help facilitate access for the fire crew. The system prevents fire from spreading, while lowering temperature.
The nozzle has a beautiful and discrete shape, which will make it blend with the style of the room. In addition, the highpressure water mist nozzle can be manufactured in any color, contributing to a more esthetically pleasing surrounding for the end user.
- Smaller pipe diameter: 12-17 mm (sprinkler: 33.7-60.3 mm), main pipe 26.9-42.3 mm (sprinkler: 89-219 mm)
- Longer life expectancy: 30-40 years (sprinkler: 15-20 years)
- Smaller tank size and pump footprint (sprinkler tank 100-1200m3) HPWM can be 5-30m3
- The damage caused by the activation of the sprinklers is greater than the damage caused by the fire
- Protection of glass, facade elements, floor tiles, old buildings up to EI60
- Small space requirements and easy installation
- There is no need to use other technologies, the high-pressure water mist system is an ideal solution for fire protection for sensitive rooms such as server rooms and archives
TRADITIONAL SPRINKLER SYSTEM
HIGH-PRESSURE WATER MIST SYSTEM
THE HIGH-PRESSURE WATER MIST SYSTEM USES UP TO 50% LESS WATER COMPARED TO LOW PRESSURE SYSTEMS AND UP TO 80% LESS WATER COMPARED TO TRADITIONAL SPRINKLERS!
IT IS CRUCIAL THAT HIGH-RISE BUILDINGS ARE FULLY AND PROPERLY EQUIPPED TO HANDLE A FIRE SITUATION. IN HIGH-RISE BUILDINGS, THE ACCESS FOR THE FIRE-FIGHTING CREW CAN BE VERY DIFFICULT, ESPECIALLY ON THE LAST LEVELS OF THE BUILDINGS. ALSO EVACUATING PEOPLE PRESENTS CHALLENGES AND LIMITATIONS.
Having a fixed high-pressure water mist system installed in high-rise buildings can make the fight against fire more efficient, with the ultimate goal of saving lives and limiting property damage.
- No need to place a large reservoir on top of the building, you can instead use the top floor for penthouse flats.
- No need for sprinkler units on more floors of the building to prevent pressure loss, the space saved can be used for other money generating purposes.
- No need for large diameter pipes. Sprinkler systems requires 3 times larger diameter riser pipes than high-pressure water mist systems.
- No need for expensive fire-resistant glass and expensive special purpose sprinkler for fire protection of glass facade.
- No need for large water supply reservoir.
FIRE PROTECTION OF DATA CENTRES
Normally a double knock pre-action system is used for protecting data centres against fires. This provides you with added safety for your data centre in the unlikely event of accidental release. The piping system is dry and nozzles are closed. When a fire is detected and confirmed by the fire alarm system, the section valve of the system opens and water flows into the actual section pipes. Only nozzles with broken bulbs are activated. This means that only the areas affected by fire will be actively sprayed.
Data centres are the heart of the IT infrastructure and are essential for day-to day business operations. It is crucial that data centres are fully and properly equipped to handle a fire situation. With high-pressure water mist, the fight against fire is more efficient, with the ultimate goal of saving lives, limiting equipment damage and keeping the data centre running.
Due to the minimal water damage to surrounding equipment and the environment, minimal downtime is achieved. Furthermore, you can keep your data centre running while extinguishing the fire.
The system can be discharged immediately upon detection of a fire – without any threat to human safety.
The modular design of the system makes it easy to extend to cover more sections as your data centre gradually expands.
No need to shut off ventilation before releasing the water mist system.
