NITROGEN-PAC™ Model SC-W

The FM Approved UNITED Fire Systems NITROGEN-PAC™ Model SC-W 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. The system provides dry air for system initial fill and nitrogen for filling the interior of a dry or preaction sprinkler system with nitrogen at 98% or greater purity.

The Model SC-W Cabinet contains the basic hardware for proper nitrogen generation, a manually-operated valve for directing the air compressor output to the nitrogen generation system or sending compressed air directly to the cabinet outlet, and manual adjustments for commissioning.

Each Model SC-W system requires one of two compatible nitrogen receivers: UNITED Fire Systems Model NR-5 or NR-10. This provides a reservoir of nitrogen, and reduces the number of compressor starts and the total compressor run time. This lengthens the life of the compressor and reduces utility and maintenance costs.

Did You Know?
  • Your dry-pipe or preaction system piping may look brand new on the outside, but what about inside? Residual water and oxygen in the pressurized air could be rusting the interior of that pipe right now. This rust can weaken the pipe, cause pinholes to form, and even clog up the sprinkler heads in the event of a fire. NFPA 25 – Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems mandates internal inspection of sprinkler pipes at least every 5 years. Are your pipes rusty? Have them internally inspected by a qualified fire protection contractor before it’s too late.
