Thermal Oxidizer & RTO Controls Support for Industrial Facilities.
Independent controls reviews, PLC/HMI modernization, alarm and trend visibility, burner-interface support, and commissioning for plant teams that own and operate industrial process equipment.
When plant teams call VIR Automation.
The first step is understanding the equipment, current symptoms, and available records without assuming the PLC or controls caused the concern.
Aging PLC or HMI
Legacy hardware, unsupported software, missing backups, or documentation gaps are making routine maintenance harder.
Recurring Trips or Unclear Alarms
Operators can see that the unit stopped, but the HMI and event history do not clearly identify the initiating condition.
Testing or Permit Activity
A recent or upcoming test, permit change, or monitoring concern calls for a bounded review of controls, instrumentation signals, and operating records.
Documentation Gaps
The running program, drawings, I/O references, alarm list, or sequence no longer match the installed equipment.
New or Modified Equipment
Controls changes need to be coordinated with the approved process, OEM, safety, electrical, and field-interface basis.
Commissioning and Handoff
The project needs disciplined I/O checkout, sequence testing, backup, documentation, and operator handoff within the authorized scope.
Signals, logic, alarms, and operating evidence in one controls picture.
VIR Automation maps the controls-side evidence around the actual equipment sequence, then identifies what can be resolved in controls and what must be routed to instrumentation, mechanical, process, environmental, OEM, or licensed-professional authority.
- Commands, feedback, permissives, interlocks, alarms, and sequence states reviewed together.
- PLC, HMI, BMS-interface, VFD, analyzer, historian, and field-signal boundaries kept explicit.
- No controls root cause or compliance outcome assumed before evidence review.
Controls support organized around plant needs.
Thermal oxidizer and RTO controls are the flagship specialty, supported by broader PLC, HMI/SCADA, modernization, commissioning, and documentation capability.

The work begins with what is actually installed and ends with a reviewable, scope-defined result.
1. Review the Evidence
Identify the running software, drawings, alarm history, trends, test timing, calibration records, and known field changes.
2. Define the Boundary
Separate controls work from field verification, process, mechanical, environmental, safety, and design-of-record authority.
3. Implement Offline
Develop and review approved PLC/HMI changes against a preserved baseline before any authorized transfer or startup activity.
4. Test and Hand Off
Record checks, unresolved holds, backups, documentation, and the verified release state without overstating completion.
Useful starting points for plant teams.
Practical guidance for gathering evidence, planning modernization, and understanding the controls architecture.
