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.
