ELLIOTT Product Lines We Repair
Our engineers are trained on the full ELLIOTT product range. Below are the major product families we service.
Elliott Governor Control Systems
Mechanical and electronic governors controlling steam turbine speed and load for refineries and power plants. Common faults include governor valve stiction, oil system contamination, and electronic control card failures causing turbine overspeed or load rejection events.
Elliott Steam Turbine Instrumentation
Vibration monitors, temperature sensors, and pressure transmitters integrated with Elliott turbine protection systems. Repairs address sensor drift, signal conditioning failures, and relay contact degradation in critical speed and load monitoring circuits.
Elliott Centrifugal Compressor Controls
Anti-surge valve control systems and pressure regulation electronics for Elliott compressors in refinery and petrochemical service. Typical issues include proportional solenoid failures, pressure transducer reading errors, and control loop instability.
Elliott Protection and Shutdown Systems
Safety-critical shutdown electronics preventing turbine damage from overspeed, over-temperature, or bearing failure conditions. Repairs require verified functional testing and compliance validation for Indian refinery safety standards.
Elliott Analog Control Cards
Legacy analog control electronics providing speed control, load regulation, and governing functions in pre-digital Elliott installations across Indian petrochemical plants. Board-level repairs address component degradation, transistor failures, and capacitor leakage.

Common ELLIOTT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELLIOTT equipment arriving at our workshop.
- ✓Governor valve stiction and sluggish response — Elliott governor oil system contamination from bearing wear debris or water ingress causes sticky valve spools, preventing smooth speed control. Oxidized oil deposits buildup on precision valve surfaces, limiting governor response time.
- ✓Overspeed trip relay chatter and false shutdowns — Elliott overspeed relay contacts suffer intermittent contact bounce or contamination after decades of operation in high-vibration refinery environments. Magnetic armature wear allows flutter during transient speed excursions, triggering unwanted turbine shutdowns.
- ✓Bearing temperature transmitter signal drift and false alarms — Elliott bearing temperature sensors experience thermistor aging, thermowell corrosion, or loose sensor contacts in hot refinery environments. Signal conditioning electronics develop capacitor leakage, distorting 4-20mA output to DCS systems.
- ✓Proportional solenoid sluggish response in anti-surge controls — Elliott anti-surge proportional solenoids accumulate magnetic coil rust and armature binding from moisture ingress or inlet system contamination. Solenoid response time degrades, preventing timely anti-surge valve opening during compressor surge conditions.
- ✓Control card capacitor failure and signal dropout — Elliott analog control cards operating for 20-30+ years in hot turbine enclosures experience electrolytic capacitor drying and leakage. Failed capacitors distort control signals, causing erratic governor response and alarm generation.
- ✓Inlet guide vane controller voltage regulation failure — Elliott compressor inlet guide vane controllers suffer regulator IC failures or transformer thermal degradation in ambient temperatures exceeding 50-55°C common in Indian refineries. Output voltage drifts, causing vane position control errors and compressor efficiency loss.

Frequently Asked Questions — ELLIOTT Repairs
Do you repair Elliott equipment anywhere in India?+
Yes. Synchronics repairs Elliott steam turbine controls, governors, and rotating equipment electronics across India. We offer PAN-India door pickup from major industrial hubs including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, Vadodara, Kolkata, and Chandigarh. All repairs are performed in our Vadodara facility with certified technicians experienced in Elliott systems.
Can Synchronics repair legacy Elliott governor systems in old refinery installations?+
Absolutely. Synchronics specializes in Elliott legacy governor electronics and mechanical controls used in Indian refineries since the 1980s and 1990s. We repair mechanical governor assemblies, analog control cards, and electromechanical protection relays. Even when spare parts are unavailable from Elliott, our engineers use component-level diagnostics and repair techniques to restore functionality without full board replacement.
What is the typical turnaround time for Elliott steam turbine control repairs?+
Most Elliott governor and control card repairs are completed within 7-10 working days. Critical refinery outages are prioritized for faster turnaround. Complex issues involving multiple circuit boards or governor mechanical rebuilds may require 12-15 days. We provide daily status updates and expedite shipping back to your facility to minimize production downtime.
How do you test Elliott control systems before returning them to service?+
Synchronics performs comprehensive functional testing of repaired Elliott equipment including governor response time verification, relay trip point calibration, signal conditioning linearity checks, and overspeed protection validation. For critical refinery applications, we document test results per ASME PTC-25 steam turbine performance standards and provide certification of compliance with Indian industrial safety regulations.
Do you provide Elliott governor oil analysis and preventive maintenance services?+
Yes. Synchronics offers Elliott governor oil condition monitoring, contamination analysis, and predictive maintenance services for refineries across India. We sample oil from governor systems, perform particle count and water content analysis, and recommend oil change intervals. This preventive approach prevents governor valve stiction issues and extends control system life in high-temperature refinery environments.
How do I send my ELLIOTT unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ELLIOTT drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on ELLIOTT repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your ELLIOTT unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
