Reduce Corrosion with a SMART Air Vent
As a fire sprinkler system is filled with a continuous supply of nitrogen gas from a Tyco® NG-1 Nitrogen Generator, the TSV-D SMART Air Vent allows oxygen-rich gas to be vented from the fire sprinkler system. Over a period of 14 days, the SMART Air Vent almost completely removes oxygen from the fire sprinkler system (< 2% oxygen). After 14 days, the SMART Air Vent automatically closes and prevents continuous venting.
The TSV-D SMART Air Vent includes two separate components: the vent assembly and electric control box. A back pressure regulator is also included to prevent total system depressurization from the vent assembly before the vent is electronically closed. The restricted venting orifice allows oxygen to be vented from the fire sprinkler system at a controlled rate to achieve a minimum nitrogen concentration of 98%.
Features
- Two components — vent assembly and electronic control box
- Includes back pressure regulator to prevent total system depressurization from the vent assembly before the vent is electronically closed
- Automatic float shut-off in the event of a system trip
- Equipped with an electronic solenoid valve that must be wired to the electric control box (conductors not included)
- Levered float valve allows gas to discharge but prevents liquid water from leaking through the restricted venting orifice if water enters the fire sprinkler system
- Support hanger not required
Benefits
No Remote Equipment
Install the vent directly at the system riser.
Reduce Corrosion
Nitrogen replaces corrosion-causing oxygen.
Extend Useful Life
Reducing corrosion can extend the service life of a fire sprinkler system.
Minimize Business Interruption
System leaks due to corrosion can lead to costly downtime – reducing corrosion helps keep systems healthy and operational.
