Deaerator Operation

Once a deaerator is installed, it’s ready to get up and running – just set it and forget it. Not quite. There is still some consideration that goes into deaerator operation. For example, although the deaerator is inspected and tested at the factory in which it was assembled, debris or minor leaks may be present throughout. Before your plant’s new deaerator starts running, you will need to perform an evaluation on the unit to ensure proper operation will follow.

After a deaerator is installed, it is within best practice to check and clean the unit, freeing of it any debris. The spray valve can be removed to make sure the valve is secured and is able to modulate properly. If any debris is found within the tank or the strainers, it must be removed before the initial start-up. Mechanical floats should be inspected to ensure that no debris is preventing the float from functioning as it should.  

Additionally, the unit’s piping connections, fittings, attachments and any adjacent piping needs to be inspected for leaks by filling the deaerator to the overflow. It’s best to inspect any and all openings and fittings for leaks. Any obstructions must be removed to properly evaluate the deaerator. Despite passing any inspections that the factory performed, shipping vibrations or installation procedures may alter the unit.

Once the evaluation is performed and the unit has been inspected, your deaerator will be ready to start functioning. Of course, after some time and use, pipe fittings may need tightening and other routine maintenance may be required.
