The modular N2G fire suppression system is used effectively where traditional extinguishing systems are less applicable. The goal is to limit the harmful effects of a fire by fighting it at the source. The N2G system is designed for placement in the room or cabinet to be protected. In some cases, an internal placement is not possible. For that situation there is a combination available intended for external placement. The N2G modular fire extinguishing system can also be used there effectively.
