Atlas Copco Oxygen Generator OGP 45

Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar.

The release of nitrogen molecules from the MS is a very slow process. This might cause a pressure build-up in the generator tanks, even after they were depressurized.

Before maintenance, make sure the generator is fully depressurized and purge thoroughly with air to remove all oxygen before service or inspection.

Always vent oxygen to the outside atmosphere.

Due to fire hazard, smoking and the use of open flames are prohibited in the vicinity of the oxygen generator.

Avoid closing valves too fast as gas velocities in the oxygen net might become too high, and create a hazardous situation.

Check the controller for information on the purity, alarms and service messages

Safety Precautions: Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar. Switch off the generator. Make sure the generator is fully depressurized and purge thoroughly with air to remove all oxygen before service or inspection. Always vent oxygen to the outside atmosphere. Avoid closing valves too fast. Smoking and the use of open flames are prohibited in the vicinity of the oxygen generator.

After maintenance activities, the service counter needs to be reset. Contact your supplier.

Oxygen sensors have to be disposed of according to the applicable regulations. The zirconium oxygen sensor and the oxygen analyzer need to be replaced as a couple.

Shut off the outlet flow after the buffer tank. (BA08)

Close the ball valve (BA09) of the purity measurement line.

Shut down the generator (generator shows OFF).

Disconnect the oxygen sensor wiring from the oxygen analyzer.

Disconnect the wiring of the oxygen analyzer.

Introduction: The Flow sensor (FI01) is optional and can be ordered in case a measurement of the outlet product flow is required; it measures the flow rate consumption. The flow sensor is to be installed downstream the buffer tank (TK04), behind the pressure regulator (RV04).

Overview of model versus flow sensor: The table below gives an overview of which flow sensor is to be used in combination with which model.
