What we repair
We service and restore VFD/VSD units used in ESP installations across multiple OEMs (including major oilfield suppliers and industrial drive platforms).
Business impact: repairing existing VFDs often reduces lead time and can provide significant savings compared to replacement.
Your current website already highlights multi-OEM capability and engineering discipline — we keep that positioning consistent.
Typical work packages
- Incoming inspection + fault isolation
- Power stage diagnostics (IGBT / power modules)
- Control/logic validation (MCU/DSP where applicable)
- Firmware restoration and parameter recovery
- Protection circuit verification
- Cooling/thermal system check
- Communication recovery (Fieldbus/Modbus/Profibus where applicable)
- Load testing / functional verification
Diagnostics that clients value
- Under-load verification where feasible (not only “power-on” checks)
- Waveform / harmonics review when relevant
- Clear “pass/fail” criteria and documented protections
- Root-cause analysis (RCA) with preventive actions
When to contact us
- Drive trips, unstable operation, nuisance alarms
- Overcurrent / overvoltage / ground faults
- Communication loss with surface control / SCADA
- Thermal issues / cooling failures
- Need for fast recovery to restore production
We can support remotely or coordinate onsite assistance depending on location and urgency.
