AQUASYS - Water Fighting with Water Mist

AQUASYS was established in 1993 as enterprise of the HAINZL INDUSTRIESYSTEME group at Linz/Danube (Austria).

Since the beginning of 2004 AQUASYS has directly been represented by a branch office in Glashütten, Germany.

AQUASYS operates globally either with partners or directly!

AQUASYS water mist technology is based on approvals, certificates and test reports of notified certification institutes such as VdS (VdS Schadenverhütung, Germany) and IBS (Institut für Brandschutztechnik und Sicherheitsforschung, Austria).

High pressure water mist systems produce a very fine water mist with droplet sizes of approx. 10 to 100 µm with high-pressure pumps with a pressure of up to 120 bar with special nozzles, which spreads almost three-dimensional gas-like.

From the fire are quickly extracted large quantities of energy and the temperature level is lowered rapidly by the reaction surface of the water droplets which is enormous to the quantity of water.

This makes a fire spread more difficult and decreases substantially the radiation heat on humans, surroundings and basic building parts. The fast fire suppression and the enormous cooling efficiency decrease the danger of a re-ignition. The fire fighting of covered areas is thus possible. Small amounts of water produce minimum damages caused by water. The disposal of person endangering and environmental damaging fire extinguishing agents is avoided.

That physiologically harmless water mist from pure water can be used without deceleration time and facilitates for present humans thereby an escape and obtains rescue and attack ways for the firebrigade.

The water mist …

- evaporates highly efficiently, withdrawing approx. 2.3 MJ of heat per litre of water from the thermal energy of the fire.

- expands to 1600 times its previous volume when it hits the flames and vaporises, causing an oxygen depletion locally at the area of the flames, which contributes to the rapid fire suppression

Following system-types are typical:

- Pre-action system with glassbulb- activated nozzles
- Wet system with glass-bulbactivated nozzles
- Dry system with open nozzles and release by a fire alarm system

Advantages of an AQUASYS- Water Mist:

• Enormously quick fire suppression
• Immediate substantial cooling efficiency
• Minimization of re-ignition danger
• Protection from radiant heat
• Almost three-dimensional extension, gas-like
• Harmless to persons
• Release without deceleration time
• Small quantity of water => minimum damage caused by water
• No disposal of chemical fire extinguishing agents
• Space-saving and simply to retrofit
• Risk and cost minimizing
