Fire protection in sensitive areas with excessive stress water mist

Finding the optimal answer for the protection of high tech gear beneath delicate environmental conditions, while on the identical time reducing the chance of contamination and taking take care of the protection of persons in case of a fire, is a constant challenge, particularly for operators of services such as laboratories, data centres, hospitals or semiconductor manufacturing services.
During the past years the high strain water mist (HPWM) expertise has been introduced extra strongly into focus of such organisations. It is a proven, dependable and revolutionary technology used for the safety of equipment equipments, different sort of buildings and important infrastructure objects. This article demonstrates how AQUASYS, a manufacturer of high pressure water mist methods accepts these challenges and supply sensible system design and individual engineering options to fulfill purchasers around the globe.

Facts about AQUASYS and excessive pressure water mist
AQUASYS is a pioneer within the growth of HPWM solutions for more than 25 years and is part of a household owned group of companies with more than 50 years of experience in fluid and automation expertise.
The outstanding impact of AQUASYS HPWM is based on water, which flows at high stress by way of specifically designed and manufactured nozzles. This process creates an extremely fantastic water mist expanding three-dimensionally and filling all kind of rooms, edges or facilities inside seconds after activation.
The very fine water mist with a droplet size between zero,050-0,300 mm literally is spread within the room. As soon because the droplets approach the fire they evaporate due to natural thermals and the volume multiply 1,675 times!
This vaporization extract the energy of 2.3 MJ per litre of water from the hearth supply. At the identical time the oxygen is displaced by the bigger quantity of the evaporated water mist. Due to the room-filling impact and the permanent feeding of latest droplets, on one hand these results in a massive cooling impact, and then again in a very good shielding of the warmth radiation and thus an insulation of the fire.
The mixture of product development, capability to execute fire tests and simulation, challenge and customer specific engineering, challenge management, component production, system installation, on-site-training in addition to service and maintenance within our company permits AQUASYS to assist our clients with revolutionary ideas and solutions worldwide.
Less water and sensible system design
The mixture of the technological advantages of water mist and using high-quality stainless steel, especially for pipes but all different components contacting water, are the main benefits of the system. No corrosion will occur and this results in the fact, that AQUASYS fire protection techniques show a significantly lower danger of contamination. Therefore, it address highest cleanness requirements. Furthermore, using high-grade stainless steel leads to longer lifetime of the system and permits using demineralised water.
The AQUASYS system with high stress water mist achieve higher effectivity and on the similar time decrease water consumption compared to widespread sprinkler methods. This results in a better system design, less space requirements and cost-reducing effects due to considerably tinier water tanks, valves, pump items and lowered piping dimensions between 12 mm to 42 mm.
The system pressure of about one hundred forty bar allows more flexibility in regards to the design of the pipeline network in comparison with other suppression methods working at lower strain. This allows longer pipe distances, more curves and flexible pipe routes without worrying about pressure loss. Particularly if the system ought to be prolonged and new areas ought to be built-in within the hearth protection system, the AQUASYS know-how shows extra flexibility in reaching the minimum required nozzle stress.
Depending on the possible power sources, ambient circumstances or house, oil-free and maintenance-free pumps with electric motor Power Pack, optionally available with diesel- or gas-powered Power Pack options are available.
Individual engineered systems
HPWM methods are individually engineered systems by each manufacturer, which additionally differs to common used sprinkler or deluge system. While the engineering focus on the individual consumer, the practical system design in addition to the interfaces for activation and communication to central fireplace alarm methods are primarily based on common standards, that are comparable and linked to other suppression systems.
Providing practical options like the availability of pre-assembled nozzle traces or special necessities for tough and delicate condition (e.g. special supports, particular and high quality material demands) the HPWM system may be completely built-in to the present structures on site and reduces the installation time on website.
Different surrounding situations (high or low temperatures, aggressive, ..), energetic air flow, in addition to all totally different kind of obstacles can even influence the system design. This require intensive coordination of all customer specific functions upfront.
Involving Backdoor engineering staff, certified with the best level of expertise and experiences, already on the first design levels enables AQUASYS to design and engineer sensible engineered techniques.
Certified and examined solutions
AQUASYS offers a assist package, that includes clarifications with customer’s fireplace marshals, approval authorities, insurance coverage firms or unbiased notified body enabling a smooth progress in each project stage. Furthermore a variety of varied check certificates for A,B,C and F fire hundreds as a background for designing the system can be found or can be done on venture specific requirements. The chance of preparation of take a look at specification, doing 1:1 real scale hearth exams including as constructed mock ups and involving specific hearth hundreds such as batteries, cables or server gear are finishing this package deal provided by AQUASYS.
