TYCO High Performance Water-Based Fire
Suppression Products

The TYCO NG-1 100, NG-1 250, and NG-1 500 Wall-Mounted Nitrogen Generators are designed to facilitate the Dry Pipe Nitrogen Inverting (DPNI) process for controlling oxygen corrosion in dry and preauction fire sprinkler systems, and provide supervisory maintenance gas. Designed for “plug and play” performance in a typical dry or preaction fire sprinkler system, the nitrogen generator utilizes membrane separation technology that produces 98%+ nitrogen on demand without the need for nitrogen storage.

The generator includes an internal bypass valve to allow for maintenance or “fast fill” needs to meet the NATIONAL FIRE PROTECTION AGENCY (NFPA) 13 30-minute fill requirement for dry pipe and preaction fire protection systems. The Nitrogen Generator is designed to nitrogen inert all of the zones being served within 14 days. Thereafter, it will continue to automatically provide supervisory nitrogen gas sufficient for pressure maintenance of the fire sprinkler system(s). The Nitrogen Generator facilitates the patented “fill and purge” breathing process in the fire sprinkler system when paired with an oxygen removal vent installed on the sprinkler riser such as the TYCO Dry Air Vent (TAV-D) or the TYCO Dry SMART Vent (TSV-D). Refer to TFP1262 for more information on TYCO Dry Air Vent (TAV-D), and to TFP1263 for more information on TYCO SMART Air Vent (TSV-D).
