Nitrogen Generator key features include the following:
-
Air Filters and Pressure Regulator
-
Membrane
-
Pressure Switch for Automatic Start/Stop (per demand)
-
Safety Relief Valve
-
N2 Storage Tank
-
STS Patented Blast-Off (optional)
Air Filters and Pressure Regulator:
The generator has three filters: the particulate, coalescing, and adsorber filters. The
particulate has a 5 micron filter that will catch any of the larger particles. The
coalescing has a 0.1 micron filter that will catch the remaining smaller particles.
Both filters feature and auto drain that will drain the water captured after the air
compressor. The drain is plumbed to the outside of the cabinet where the end-user
can then connect ¼” tubing and drain to a safe location. The adsorber filter captures
0.003 ppm/wt oil content.
Pressure Switch for Automatic Start/Stop (per demand):
The generator comes with a built in pressure switch to indicate when the nitrogen
demand is needed or has been met. When the pressure switch is triggered (nitrogen
storage tank pressure is met), it will pause the production of nitrogen to the tank.
Once the pressure switch is reset (automatically reset when pressure fall 7-10 PSIG
below set pressure), it will resume the production of nitrogen to the storage tank.
Safety Relief Valves:
Safety Relief Valves have been placed throughout the system for maximum safety.
They are designed and put in place to minimize failure of other components. They
all come with an ASME stamp.
N2 Storage Tank:
A N2 Storage Tank is housed inside the cabinet with manual ball valves and gauge.
It is plumbed to an external manual ball valve so that the end-user will not have to
do any plumbing within the cabinet.
Patented Blast-Off Detection (optional):
The Blast-Off Leak Detection will provide the end-user with an alarm when it
detects characteristics of a leak somewhere on the system. It will trigger an audible
alarm, display it on the screen, and the end-user can tie into the dry contact so that
the alarm can be relayed back to the Building Management System (BMS).
