True Advanced Purge (TAP)

Description

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.

Features

  • Automatic initial purge sequence for removal of air from sprinkler system piping and replacement with 98% nitrogen.
  • Automatic sampling of gas from inside the pipe and permanent display of nitrogen concentration.
  • Easy to read front panel display of nitrogen concentration, purge status, time, and date.
  • Mounts separately from associated purge vent assembly and connects with plenum-rated tubing.
  • Advanced, self-calibrating gas sensing technology with long sensor life.
  • Relay output for system fault remote notification including low nitrogen concentration after automatic initial purge sequence.

Benefits

  • Eliminates manual operation of ball valves to regulate purging.
  • Eliminates manual use of hand-held nitrogen analyzer to measure nitrogen concentration in the pipe.
  • Read nitrogen value at eye level – no need to climb up to purge vent locations.
  • Unit requires no periodic calibration.
  • Local and remote signaling of fault conditions.
  • Automatic purge sequencing minimizes compressor run time, lengthening compressor life and reducing energy consumption cost.

Did You Know?
  • If you have a dry standpipe in your structure, can you tell if it’s intact and ready for fire department use? If it’s not, the risk is high.  Be sure – a UNITED Fire Systems STANDPIPE-PAC system will alert you if someone accidentally leaves a valve open or even disassembles a portion of the standpipe inadvertently.
