A centrifuge control panel can operate for years before its age begins to affect reliability and maintenance. Sometimes the warning signs are obvious, like recurring shutdowns or failed components. Others develop gradually, making the system harder to troubleshoot or less responsive to changing operating conditions.
7 Things We Look for When Evaluating a Centrifuge Panel Upgrade
At Integrity Control Services (ICS), we work with centrifuge operators who want to extend the life of their existing equipment. Here are seven signs we look for when evaluating whether a control panel needs an upgrade.
1. Your Main Drive Has Failed
The main drive is often the single most expensive component in a centrifuge control panel. On some systems, it can account for close to 25% of the overall cost of the panel.
When that drive fails and can’t be repaired, replacing it becomes a significant purchase on its own. Installing a brand new drive into an aging control system means you’re still left with the obsolete PLC, worn HMI, and other legacy components around it.
That’s why a main drive failure is one of the best times to upgrade the entire panel. Since a large part of the investment is already being made, upgrading the remaining controls at the same time brings the whole panel up to date in a single project, rather than scheduling another shutdown for those upgrades later.
2. Faults and Shutdowns Are Becoming More Frequent
Occasional faults don’t necessarily mean your panel needs replacing. But recurring drive trips, unexplained shutdowns, or inconsistent startup behavior deserve attention.
We look at drive diagnostics, feedback signals, and control sequences to determine the cause of the interruptions. When failures recur and existing controls make diagnosis difficult, a retrofit may be a more practical long-term solution than repeated repairs.
3. You’re Missing Important Operating Data
Reliable centrifuge operation depends on accurate information about what’s happening inside the machine.
If your controls don’t provide useful torque readings, speed feedback, bearing temperature monitoring, or fault information, your maintenance team may have difficulty identifying developing issues.
Modern control systems can make this information easier to access, helping operators recognize changing conditions before they interrupt production.
4. Replacement Parts Are Getting Harder to Find
Older programmable logic controllers (PLCs), variable frequency drives (VFDs), and communication modules eventually become obsolete.
If you’re sourcing discontinued components through secondary suppliers or maintaining an extensive inventory of spare electronics, it’s worth evaluating a control system upgrade.
A retrofit can replace aging hardware while retaining usable portions of the existing cabinet and wiring.
5. Your HMI Is Becoming Difficult to Use
Faded displays, unresponsive touchscreens, and limited diagnostic information can make everyday centrifuge operation more frustrating.
Your human-machine interface (HMI) should give operators clear information about equipment status, alarms, and operating conditions.
For centrifuges used outdoors, screen visibility is especially important. Modern HMI replacements can provide clearer displays and more useful diagnostics without requiring replacement of the centrifuge itself.
6. Troubleshooting Takes Too Long
Some older panels rely on complex communication protocols that make it difficult to trace faults across controllers, drives, and other equipment.
Legacy networks aren’t automatically a reason to upgrade. However, if technicians spend excessive time tracing communication failures or navigating poorly documented wiring, the control architecture may be adding unnecessary maintenance time.
Modern communications and updated electrical drawings can make future troubleshooting considerably easier.
7. Heat and Vibration Are Affecting Panel Components
Centrifuges often operate in demanding environments. Poor cabinet ventilation, failed cooling fans, and excessive vibration can shorten the life of sensitive electronics.
These conditions don’t always require a complete panel retrofit. Sometimes maintenance or targeted repairs are enough.
When component failures become recurring issues, however, improving the cabinet layout, cooling, and vibration protection may be part of a larger modernization effort.
What a Centrifuge Control Panel Retrofit Looks Like With Integrity Control Services
A centrifuge panel retrofit starts with a practical question: What can we keep, and what needs to change?
Because Integrity Control Services is vendor neutral, the answer isn’t tied to any single brand. We work with controls from Yaskawa, Fuji, Schneider Electric, Eaton, Allen-Bradley, LS Electric, Beijer, Omron, Nidec, and many others. That flexibility lets us build around the equipment you already have, stay with the platform your maintenance team knows, or recommend the hardware that best fits your application.
For an oil and gas customer operating a fleet of decanter centrifuges, we reused the existing cabinets and upgraded the controls inside. We replaced a complicated Profibus and DeviceNet architecture with Ethernet-capable hardware, improved access to operating data, and installed daylight-readable HMI screens.
We also improved cabinet airflow and added vibration protection. The upgrades reduced troubleshooting time and downtime while making the controls easier to maintain.

Our centrifuge panel upgrade services cover controls engineering, panel modifications, and commissioning. We can also handle PLC retrofit and upgrade services when older controllers need to be replaced.
Is It Time to Upgrade Your Centrifuge Controls?
If several of these warning signs sound familiar, our engineers can evaluate your existing panel and help determine what needs attention.
Integrity Control Services provides centrifuge controls and panel support for existing systems, as well as 24/7 emergency automation repair when unexpected failures disrupt production.
