SYSTEM TYPES
Fogex Water Mist Fire Protection Systems are supplied in two forms;
- Pump systems
- Pressure Skid Modules (PSM's)
Pump Systems:
Fogex pump systems comprise of either electric high pressure piston pump(s) or Diesel high pressure piston pumps.
High pressure piston pumps are connected to the water supply and to the Stainless steel distribution pipe work that contains the water mist nozzles. Pumps have local automatic and manual start/stop panels and are supplied complete with RX3 unloaders, pressure gauges, pressure sender switches, ammeters, electric (or Diesel) motors, mounted onto a heavy duty Galvanized steel base or frame with anti-vibration mounts. Pump cabinets are IP rated forthe specific hazards.
Diesel pump sets are supplied with over-speed regulators, batteries and leads, RX-3 unloaders, ammeters, local auto start/stop panel, fuel tank, radiators for engine cooling (if water cooled engines are used), exhaust manifold all mounted onto a heavy duty Galvanized steel frame or base with anti-vibration mounts.
High pressure pumps are heavy duty design and manufactured with strict Quality Assurance procedures. We 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 be either automatically or manually started and stopped. High pressure piston pumps range in sizes and flows from several litres per minute and in excess of 316 litres per minute. Some picture examples of electric high pressure piston pumps can be seen below.

Pressure Skid Modules:
Fogex Water Mist Fire Protection System can be supplied as self contained Pressure Skid Modules (PSM's). 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 corrosion and internal discolouration of water. Dry Nitrogen gas is used for system pressurisation.
Fogex PSM's are manufactured and supplied in various sizes and arrangements. PSM's can be supplied "loose" meaning that the water and Nitrogen bottles can be bracketed to a nearby wall or Fogex PSM's can be supplied in a steel cradle or skid. Fogex Stainless steel high pressure actuator heads compliment the PSM's. Pressure gauges, pressure sender switches and Fogex high pressure 24VDC electric %4-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. Atypical small Fogex PSM is shown in the picture.
