The True Advanced Purge™ Model TAP-G3 is designed to automatically purge air from within a dry-pipe sprinkler system 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.
