  • Droplet size 100 to 350 microns
  • Mist generated by water flowing through swirl chambers

FOGEX has been tested in accordance with IMO Guidelines MSC/Circ. 668/728, MSC/Circ. 1165 for use in machinery spaces and cargo pump rooms (upto 4,000m³), IMO MSC/Circ. 913 for local applications and Factory Mutual Research Corporation combustion turbines, machinery spaces, and special hazard machinery spaces for enclosures up to 500m³. 

Pump Systems

FeaturesOperation/Descriptions
  • Heavy-duty designed
  • Manufactured in accordance with strict Quality Assurance procedures
  • Offer an extensive range of high-pressure piston pumps to suit any sized project
  • When more than one pump is supplied on a project, the pumps are manifolded together to deliver the correct quantity of water and pressure under continuous flow
  • Pumps can automatically or manually started and stopped
  • High-pressure piston pumps range in sizes, flows from several litres per minute and in excess of 330-litres per minute

FOGEX pump systems comprise either electric high-pressure reciprocating piston pump(s) or diesel high-pressure reciprocating piston pumps. Pneumatic driven pumps are also possible upon request.

High-pressure piston pumps are connected to the water supply and to the stainless steel distribution pipe network that contains the water mist nozzles. Pumped systems are supplied with state-of-the-art PLC pump controllers and a local water mist control panel having automatic and local manual start/stop features. Fire pump skids are supplied complete with all accessories such as pump unloader valves, S/Steel pressure gauges, pressure switches, ammeters, electric (or diesel) motors, high pressure basket inline water filters, non-return valves, manual isolation ball valves, 24VDC section valves, Y-strainers etc all mounted onto a heavy duty Galvanized steel frame with eye lifting lugs and anti-vibration mounts. Pump cabinets are IP65 NEMA-4X rated and can be supplied as explosion proof versions for specific hazards.

Diesel fire pump sets are also supplied with the above accessories including over-speed regulators, batteries and leads, ammeters, local auto start/stop panel, fuel tank, radiators (or cooling loops) for engine cooling, starter motor, drive shafts with safety guards and exhaust manifold. 

Pressure Skid Modules

FeaturesApplicationsOperation/Descriptions
  • FM approved for use in combustion turbines
  • Machinery spaces
  • Special hazard machinery spaces up to 500m³
  • Under FM Approvals the system running time is 18.5 minutes for extra safety and combat ability

FOGEX Pressure Skid Modules can be either stand-alone systems where it is impractical to install a fixed pipe work system, e.g. Diesel generators or combustion turbines located in remote areas. FOGEX Pressure Skid Modules can also be used as a back-up water mist firefighting system or used as a first shot system before the main fire pumps start up, e.g. for use in passenger vessels. 

The FOGEX water mist fire protection system can be supplied as a self-contained Pressure Skid Module (PSM). The quantity of water contained is determined by hydraulic calculations based on type and quantity of nozzles installed and the desired system running time. High-pressure lined steel cylinders are used to avoid the possibility of internal corrosion or discolouration of water. Dry nitrogen gas is used for system pressurisation.

FOGEX PSMs are manufactured and supplied in various sizes and arrangements. PSMs can be supplied “loose” meaning that the water and nitrogen bottles can be bracketed to a nearby wall or they can be supplied in a steel cradle or skid depending on customer preference.

FOGEX stainless steel high-pressure actuator heads complement the PSMs. Pressure gauges, pressure switches, and FOGEX high-pressure 24VDC electric turn actuator ball valves are also supplied and fitted onto the PSM. FOGEX high-pressure stainless steel gas manifolds and regulators may also be supplied, where desired. FOGEX PSM water bottles remain un-pressurised until the system is activated.

Nozzles

NozzlesOperation/Descriptions
  • Smallest and lightweight
  • Less than 30 grams, means less system weight
  • Reduced clutter
  • Enhance the aesthetics of an engine room compartment
  • Do not protrude
  • No moving parts ensure no nozzle failures to increase reliability

FOGEX® nozzles are flow and pressure tested to the system design pressure before export. Automatic glass bulb nozzles are also pressure & flow tested to the system design pressure and then up to 120-bar g to ensure no failure. Every automatic nozzle is pressure tested prior to sale to ensure no leakage.

FOGEX open deluge nozzles are a one-piece construction and are supplied complete with a stainless steel filter.

FOGEX automatic glass bulb nozzles are sometimes pressure tested up to 400-bar to ensure structural integrity and the glass bulb remains intact even under these elevated pressures. FOGEX automatic water mist nozzles are supplied with approved bulbs and they can be supplied in various temperature activation ranges depending on application.

FOGEX automatic nozzles are also supplied with internal filters and have the same flow rates and spray angles and thread sizes as the open deluge nozzles.

FOGEX nozzles use the least amount of water for fighting fires and they are manufactured and supplied either in Stainless steel or Aluminium Nickel Bronze (depending on customer choice). Both nozzle material types have been environmental tested as per IMO MSC/Circ. 668/728 by Factory Mutual (Project Identifier No. 3007879) and FILK Laboratories in South Korea.
