My nitrogen-hydrogen flow control panel seems to be working properly, but is there anything I should be checking?

There are many aspects of a flow control or blend panel that require periodic maintenance for proper functionality—especially those related to its safe operation.
You should check the operation of the solenoids to help verify that the combustible gas flow is automatically turning off and the inert gas purge is automatically turning on as intended. They should be tested in accordance with recommended maintenance frequency—typically every six months. Plus, you should rebuild the solenoids as needed. It’s also important to check the purge timer setpoint to help confirm that it can adequately purge the furnace. And you should verify and document the low-flow alarm setpoints on the inert gas purge and process flows.
These are just some of the items that should be reviewed on a regular basis. For more information, please give us a call at 800-654-4567.
