Most fire protection service companies treat nitrogen generators as an afterthought. NGT was founded to fill that gap — with 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.
With a distributed technician network across the U.S., we reach your site faster than regional providers — with no third-party subcontracting.
We stock OEM and aftermarket components for virtually all major generator brands, eliminating weeks-long lead times that can leave your system offline.
Every service visit produces inspection-ready reports formatted for AHJ submission, insurance requirements, and FM Global compliance.

"NGT had a technician on-site within 36 hours of our emergency call. They diagnosed a failed membrane module, had the part on hand, and got our suppression system back online the same day. No other company we tried could match that response."
"We manage fire protection across 14 data center properties. NGT is our go-to for anything nitrogen — they know these systems inside and out, and their documentation holds up during every AHJ inspection without question."
"Switched our preventive maintenance contract to NGT two years ago and haven't looked back. Our generator uptime is the best it's ever been, and the annual service reports have made our insurance renewals significantly smoother."
