TECHNICAL INFORMATION
SYSTEM DESCRIPTION AND CONFIGURATION

The 1230 Clean Agent System uses Novec 1230 fluid developed by 3M. The fluid is stored in steel cylinders, pressurised with nitrogen to 34.5 bar at 21℃. The cylinder valve outlets are connected to distribution pipes with discharge nozzles via flexible hoses.
The cylinder valve assembly can be equipped with a supervisory pressure switch connection for monitoring cylinder pressure, a pressure gauge and a safety burst disc. The valves can be activated electrically, pneumatically or manually.
Installations can be flexible depending on storage accessibility:

Central system

• Cylinders can be located in a centrally stored bank outside the protected space
• Distribution valves and piping are provided for each space

Modular system

• Cylinders can be evenly located inside or adjacent to the protected space
• Duplicated release lines connecting the cylinders are required

Extinguishing fire using NOVEC 1230
The 1230 Clean Agent System uses Novec 1230 which is stored as fluid and dischared as gas. The system extinguishes fire by removing the heat from the fire while it absorb the heat at its low boiling temperature.
A low design concentration of 4 to 6% in combination with a high No Observable Adverse Effect Level (NOAEL) of 10% gives a safety margin of up to 100%. The US EPA Significant New Alternatives Program (SNAP) classifies Novec 1230 fluid as acceptable for use as a total flooding agent in occupied spaces.

SYSTEM APPLICATIONS

• Machinery spaces Category A
• Cargo pump rooms
• Paint and flammable liquid lockers
• Control rooms
• Switch board rooms
• Any spaces needing fire protection (also possible for inerting spaces)
• Cargo compressor rooms on gas tankers

The system is applicable where space is a premium, and can protect high/low voltage switchboard rooms and computer service installations.

Tankers

Oil tankers

LPG

RULES AND REGULATIONS
The 1230 Clean Agent System fulfils the requirements of IMO MSC/Circ. 848 and MSC.1/Circ. 1267, and is equivalent to Fire Extinguishing Systems required by SOLAS 1974 as amended, Chapter II-2.
The system can be applied on merchant maritime and offshore structures as design is in accordance to SOLAS, class requirements and IMO MODU Code.
