How AquaMist Works

• Evaporation (heat extraction) is afunction of surface area of droplets

• Reducing droplet size increases sur-face area

• Increase in surface area allows forlarger cooling effect for a given flow

• Water converts to vapor expandingby a factor of 1650 times

• Oxygen is displaced and diluted,thereby blocking it from the fuelsource

• Higher heat level causes a fastervaporization

LARGER DROPSPENETRATE TO

BURNING SURFACE

• Fire extinguishment is improvedwith direct contact of water droplets

• This type of extinguishment is nor-mally associated with standardsprinklers

• Important part of operation if venti-lation is a factor and Class A com-bustibles are present

BLOCKS RADIANTHEAT AND

COOLS GASSES

• Small water droplets tend to remainsuspended

• The expanding mist will expand andcool the gases and other fuels in thearea

• Blocks the transfer of radiant heat tothe adjacent combustibles and pre-wets them

Required Outlet Strainer –The pipe, fittings, hangers andAquaMist nozzles are to be connected to the strainer outlet.

The “MCC” Pump Skid Package is the self-con-tained control center of the AquaMist® System. Thecompact skid unit has been professionally designed andassembled to ease system installation and to meet themost stringent project requirements.

To System

• Power must be provided for the controlcabinet and pump controller

• Detection circuits must be installed andwired to the control cabinet

• An adequate water supply must be pipedto the pump supply piping inlet

AM10 AQUAMIST® Open Type Mist Nozzle

AM4 AQUAMIST® Open Type Mist Nozzle

AM15 AQUAMIST® Open Type Mist Nozzle

• Open spray nozzles

• Designed for use in water mist systems protecting flammable liquids and turbinebearings

• Minimal water demand, approximately 3.1 GPM/nozzle at 170psi (11,73 lpm at 11,6 bar)

• Mist represents latest in fire protection technology

• For use in “low pressure” mist applications

• Minimum operating pressure is 170 psi (11,6 bar)

• Listed & Approved – UL, FM

AQUAMIST® Systems utilize the newest and most unique nozzles developed and approved for fire protection. They offer an alternative to gaseous, foam, and heavy density sprinkler sys-tems. By utilizing a higher pressure than a normal sprinkler system, but a 50-80% lower waterflow, the AquaMist Systems use less water more effectively, reduce pipe sizes and labor costs,and minimize cleanup and water damage.

• Listed & Approved – Marine Type Approvedby Lloyds, USCG, DNV, American Bureauof Shipping, MCA, Germanischer Lloyd,Bureau Veritas

• Intended Applications – IMO MandatedLocal Application System for Protection ofClass A Machinery Spaces

• Maximum Distance between nozzles (toplane of protection) - Vertical ClearanceNozzle Spacing
