The Unitor local application fire-fighting system is approved by major Classification Societies and accepted by flag authorities for use as a local fire protection system for high risk areas, such as main and auxiliary engine top, burner for boilers & inert gas generator & incinerator and purifier for heated fuel oi.
The system has been extensively tested according to IMO MSC/Circ.913 and Circ.668 App.A.
Features and benefits
- Complies with SOLAS and approved by major classification societies (IACS)
- MED (Marine Equipment Directive) approved nozzle
- Extensive independent testing according to IMO MSC/Circ.913 and Circ.668 App.A
- Low working pressure (4 bar) – low installation cost using PN16 dry piping system
- No need for supply of pump if suitable pump onboard can be utilised
- Components can be delivered in modular units, reducing shipyards installation work
- Minimal and easy maintenance
- Safe and secure for crew
Technical Design
The low-pressure water nozzles are located in a grid pattern at an approved distance from the equipment to be protected.
The local application system utilises low pressure PN16 piping between the pump station and nozzles.
Separate protected objects/areas have individual dry piping leading from selector valve register to the nozzles.
The piping only contains water during operation of the system.
The selector valves, one for each protected object/area, are remotely operated from the centrally-located main control panel or from manual release boxes near the protected objects/areas.
The valves can also be operated manually. Our system design allows for the use of both fresh and/or sea water which is accepted by the rules.
In unmanned machinery spaces, release of the local fire fighting system is activated automatically by means of detection, as well as manual from either central or localised cabinets. For attended machinery spaces, automatic release is not required.
Pump, valves and control panels can be delivered on skid units, thus reducing the cost of installation.
