Sizing your job

Sizing your nitrogen generator system requires three important pieces of information:

1

Supervisory Pressure

This is the air pressure required to keep the dry valve closed, usually ranging between 20 and 40 PSI.

2

Largest Riser in Gallons

This is the total volume (in gallons) of the largest riser to ensure NFPA requirements of 30 minute fill time.

3

Total System Capacity

This is the total volume (in gallons) of all the risers that being supplied by the Nitrogen Generator.

Integrated Systems

NGP-250

Potter's line of Integrated Nitrogen Systems is designed specifically for smaller dry and pre-action fire sprinkler systems. When space is a premium, these units easily fit where others can't. Just pipe directly from the nitrogen outlet to the air maintenance device to start protecting the system from corrosion. Completely skid mounted.
