NITROGEN-PAC™

Nitrogen Generator Systems

The UNITED Fire Systems NITROGEN-PAC™ is a fully integrated nitrogen generator system to introduce high-purity nitrogen into preaction or dry sprinkler piping. NITROGEN-PAC™ replaces the existing air compressor, providing the necessary supervisory pressure in the form of nitrogen instead of air. NITROGEN-PAC™ occupies minimal space, operates quietly, and can be installed near your sprinkler system riser.

Why Choose NITROGEN-PAC™?

The NITROGEN-PAC™:

  • Lengthens the life of the pipe
  • Helps prevent pipe wall thinning, pinhole leaks, and rust that clogs sprinkler heads
  • Offers reliable, dependable protection that works
  • Comes with expert field and in-house technical support

NITROGEN-PAC™ SC SERIES

The NITROGEN-PAC™ SC (Self-Contained) Series is a family of FM Approved nitrogen-based sprinkler corrosion inhibiting systems, providing high-purity dry nitrogen for the interior of preaction and dry sprinkler piping. These units feature a compressor for system fast-fill and nitrogen generation, refrigerated drying of the air for the lowest possible moisture content, and membrane technology for efficient nitrogen generation. The SC Series factory-assembled units save space and shorten installation and commissioning time.

Product Information

NITROGEN-PAC™ M SERIES

The NITROGEN-PAC™ M (Modular) Series from UNITED Fire Systems is a unique approach to supplying nitrogen for sprinkler systems. The modular concept allows for the choice of components perfectly sized for the application. Many small to mid-sized systems need an engineered system approach for both proper application and cost-effectiveness. The NITROGEN-PAC™ M Series permits our expert designers to choose the components that fit your application—with no compromise of protection or dollars.

Product Information

NITROGEN-PAC™ SC-W

The FM Approved NITROGEN-PAC™ Model SC-W (Self-Contained Wall-Mount) is a part of the SC Series; it is a completely self-contained nitrogen-based sprinkler corrosion inhibiting system. The unit is factory assembled and tested, and is ready for connection to sprinkler system riser(s). The system contains an air compressor, filters, and a membrane device to perform nitrogen separation.

Product Information

TRUE ADVANCED PURGE™ (TAP)

The UNITED Fire Systems True Advanced Purge System Model TAP-G3 is designed to automatically purge air from within a dry-pipe or preaction sprinkler system and replace the air with 98% nitrogen from a NITROGEN-PAC™ sprinkler corrosion inhibiting system. The system also automatically samples, analyzes, and displays the percentage of nitrogen within the pipe.

Did You Know?
  • Your wet-pipe sprinkler system may not be as filled with water as you expect it to be. A bubble of air may migrate to the highest point in the system, creating a very vulnerable location for internal pipe corrosion. That’s why NFPA 13 now requires that all new wet sprinkler systems be fitted with an air vent at the system’s highest point. This is a good investment for both new and existing systems. The UNITED Fire Systems Model AR-1 automatic air vent device is Factory Mutual (FM) Approved for just this function. See here for more information, and take action to prevent damaging corrosion.
