Fire Suppression in Data Centers and Critical Facilities

By Staff Reporter, 04 June, 2025

Johnson Controls' Hygood® Inert Gas System 300 (IGS-300) simplifies fire suppression in buildings with valuable or sensitive assets.

The solution is suitable for a wide range of applications including control rooms, data centers, electrical switch rooms, financial institutions, museums, laboratories, medical facilities, petrochemical, oil and gas facilities, air traffic control towers, archives, mining centers, telecommunication sites, cultural and historic sites and e-houses.

"With the launch of the new Hygood Inert Gas System 300, we expect our specifying customers will leverage the simplified design and installation features to be more competitive in winning projects," says Beth Bjorlo, product management director at Johnson Controls. "This system represents a significant step forward in both fire protection safety and efficiency, providing our end users with peace of mind and dependable protection for their assets."

The Hygood IGS-300 utilizes clean agents INERGEN® or IG-55, coupled with enhanced regulated flow technology and simplified actuation, to effectively extinguish fires while minimizing turbulence during discharge.
