FOR DRY PIPE AND PREACTION FIRE SPRINKLER SYSTEMS WITH NITROGEN
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.
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.
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.
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.
