NN100 Suppression System

The Clean and Green Solution

About Nitrogen gas

The NN100 System by NOHMI extinguishes the fire by discharging the nitrogen gas into the protected room. This help to reduce the oxygen concentration in the room to below 15% which is a cut-off point for continuous combustion.

The discharge of nitrogen gas does not cause any problem with visibility necessary for occupants to access exits since no condensation in the air take place on discharge. NN100 System is excellent to protect critical infrastructures and rooms containing precision instruments such as Data Centre, Server Room, Electrical & control rooms, Documents storage, Medical Treatment Rooms, Fine Arts etc.
