Marine N2 Fire-fighting System
Description：
Nitrogen fire extinguishing system is one of the new substitutes for halon extinguishing agent. It has the characteristics of environmental protection and high efficiency. It is widely recognized in the world and is widely used in various fire-fighting places. Compared with other commonly used halon substitutes HFC-227ea and CO2, nitrogen has great advantages and broad application prospects.
With colorless, odorless, non-corrosive, non-conductive and non-residue superiority, it is widely used to sea-going ships, mines, docks, etc.
Principle：
Physical fire extinguishing characteristic.
Nitrogen is to reduce the oxygen concentration so that it does not support combustion. It does not produce any chemical reaction, has no corrosive effect on objects, and it is non-conductive, and is easy to clean up after a fire.
Advantage:
1. Environmental protection and energy saving. Nitrogen is the main gas component in the air and does not produce any greenhouse effect and does not destroy the ozone layer.
2. High security. Nitrogen fire extinguishing system can be used in places where people work, and there is enough time to escape when spraying. Compered that HFC-227ea extinguisher system irritates the human respiratory tract and is easy to suffocate carbon dioxide is low in safety, not only suffocating, but also has a fast cooling effect.
