Open, directional mist nozzles • They are intermediate pressure nozzles which utilize a single fluid jet impinging on a diffuser to produce a spray having a range of water droplet sizes suitable for the extinguishment of Class B fires, as well as incidental Class A fires • Maximum utilization of water for flammable liquid fire protection.
AM10 & AM10B Non-Automatic Open Type
Listed and Approved for Marine Type Approved by Lloyds, USCG, DNV, American Bureau of Shipping, MCA, Germanischer Lloyd, Bureau Veritas • Intended Applications – IMO Mandated Local Application System for Protection of Class A Machinery Spaces • Nozzle pressure: 12,1 to 17,2 bar.

How the AQUAMIST System Works
Tech Data Sheet
TFP2270
1 •
• Reducing droplet size increases
The “MCC" Pump Skid Package is the self-contained control center of the AQUAMIST System. The compact skid unit
has been professionally designed and assembled to ease system installation and to meet the most stringent project requirements. • Power must be provided for the control cabinet and pump controller • Detection circuits must be installed and wired to the control cabinet. • An adequate water supply must be piped to the pump supply piping inlet.
2 • Water converts to vapor expanding by a factor of 1650 times
• Oxygen is displaced and diluted, thereby blocking it from the fuel source
• Higher heat level causes a faster vaporization
4 • Small water droplets tend to remain suspended
• The expanding mist will expand and cool the gases and other fuels in the area
• Blocks the transfer of radiant heat to the adjacent combustibles and pre-wets them

3 •
Fire extinguishment is improved with direct contact of water droplets
Evaporation (heat extraction) is a function of surface area of droplets
surface area
• Increase in surface area allows for larger cooling effect for a given flow
• This type of extinguishment is normally associated with standard sprinklers
• Important part of operation if ventilation is a factor and Class A combustibles are present
