Smith 3-Stage Low-Pressure Nitrogen Generator – Special Purpose Model 16391

Description

Description

This preset three-stage regulator is specially designed to deliver a highly accurate and consistent low-pressure supply of nitrogen to oil-filled power transformers. The regulator will deliver and maintain 0.50 PSIG in the headspace of oil-filled transformers. A built-in self-relieving valve set at 8 PSIG protects the system from over-pressurization due to temperature variation. Both models come with a rapid-fill bypass pressure valve allowing the rapid filling of the transformer with 6 PSIG of pressure.

• This special-purpose regulator is designed to supply constant pressure nitrogen to oil-filled substation power transformers.

• This regulator will maintain oil-filled transformer atmospheres at approximately .5 PSIG.

• This design is constructed with a two-stage preset regulator connected to a highly sensitive single-stage regulator that maintains a .5 PSIG outlet pressure.

• A built-in self-relieving valve set at 8 PSIG protects the system from over-pressurization due to temperature variations.

• This unit is also designed with a purge valve that has a preset pressure of 8 PSIG which is connected to the second stage allowing quick gas filling of transformers.

• This highly reliable design provides constant outlet pressure and flow.

• Adjusting screws are concealed to prevent tampering.
