The FRM3600 is a fixed ratio gas mixer for argon, carbon dioxide, helium, nitrogen, and oxygen. The mixer is suitable for different applications; such as welding, modified atmostphere packaging, process control and other similar applications. The gas mixture is preset at the factory. The gas mixture can be changed in the field with the assistance of a gas analyzer. The FRM3600 gas mixer will deliver a constant gas mixture concentration up to 3600 scfh while the mixer is still cycling.

STANDARD FEATURES

• Mixer is still cycling at 3600 scfh.

PRINCIPLE OF OPERATION

The supply gases are individually filtered at the inlet of the mixer to remove particles. the pressure of each gas is then regulated at the exact same pressure before entering their respective flow restrictors. The flow restrictors are adjusted to ensure the requested gas mixture. The gases are blended in a mixing tee before entering the surge tank. The tank is constantly monitored by a pressure switch which actuates the solenoid valve on and off to allow the mixture to fill the surge tank at a constant pressure and flow. The mixture pressure is controlled by a line regulator before entering the pipeline.
