ExxFire is a disruptive industrial fire suppression company, using patented pressureless nitrogen gas storage technology called Cool N2 Gas Generators (CGG). These replace high-pressure gas tanks with a safer, greener, easier to handle, and maintenance-free alternative. The nitrogen gas released from CGGs potentially offsets 7-10 megatons of CO2 equivalent p.a. from current solutions, whose cylinders filled with environmentally impacting chemical or CO2 gas. The CGGs technology, available for business-critical cabinet protection with integrated smoke or heat detection, is sold/installed worldwide. The CGGs technology is being scaled to larger volumes to enter the largest part of the €4.6bn global market, providing a safe, green and more economical alternative. A segment is preventing the start of thermal runaways of lithium-ion battery energy storage systems (BESS) that otherwise end in fire and possibly in explosions and a 2nd segment is the ever-growing data center segment.
