Open a control cabinet that has spent five years inside a process building and the story is written on the components: dull gray films on copper, terminal screws bleeding rust, a relay that clicks but no longer makes. Nothing dramatic happened. The air did it, slowly, and one morning a unit drifting toward failure finally quits.
IVS Incorporated has repaired industrial automation equipment for over three decades, and units from process environments get treated as chemistry problems as much as electrical ones.
The New Orleans region anchors one of the densest concentrations of process industry in the country. Chemical and petrochemical plants line the river corridor upstream toward Baton Rouge, producing intermediates, resins, fertilizers and industrial gases, each running drives, motor control centers and controllers continuously. Refining and downstream processing add to that load, and the service firms and fabricators supporting them make up an economy of their own.
The waterfront carries the rest. Shipbuilding and marine fabrication, barge and vessel repair, and bulk terminals handling grain, coal, ore and containers all depend on cranes, ship loaders, conveyor drives and handling controls. Food and beverage production, coffee processing, metals work and equipment shops round out a base spread across Orleans, Jefferson and St. Charles parishes.
Process atmospheres punish hardware in ways plant managers underestimate until they compare failure rates between buildings. Chemical vapor, acid mist, hydrogen sulfide, chlorides and particulate migrate into enclosures through cable entries, vents and doors opened on rounds. Sulfur-bearing atmospheres tarnish silver and copper into creeping sulfide films that grow across boards and up connector pins. Chlorides pit plating and undermine solder joints. Acid mist attacks exposed metal, and terminal blocks, relay contacts and edge connectors are all exposed metal.
The result is failure by degrees rather than by event: rising contact resistance, intermittent signals, connectors that read good under a probe and open under vibration, boards where the trouble is residue rather than a failed component. That is why cleaning and protection carry as much weight here as the electrical repair. A board from a plant atmosphere is cleaned thoroughly before diagnosis, because a contaminated board hides its own faults. After repair, conformal protection and proper reassembly of seals and gaskets matter, since returning a repaired unit to the same atmosphere without closing the contamination path simply restarts the clock.
Two resources worth handing to your electrical crews: PLC troubleshooting and maintenance and how to test a servo motor, both aimed at catching problems while a unit still runs.
