Most fire protection service companies treat nitrogen generators as an afterthought. NGT was founded to fill that gap, bringing the specialized knowledge, parts inventory, and national reach to get the job done right.
We don't split our focus. Every NGT tech is trained exclusively on nitrogen generator systems, giving you deeper expertise than a generalist fire protection company can offer.
Our specialized technicians are based in the Midwest and travel nationwide. We fly for long-distance jobs and drive for regional work. You always get the same dedicated expert, never a subcontractor or franchise tech.
We recommend your fire protection contractor be present during site visits. Our work is most effective when the full system team is aligned from the start.
