IHI Product Lines We Repair
Our engineers are trained on the full IHI product range. Below are the major product families we service.
IHI Gas Turbine Control Systems
Advanced control and instrumentation systems for IHI gas turbines used in power generation and cogeneration plants. Common issues include sensor signal loss, flame failure detection faults, fuel control valve malfunction, and combustion instability problems.
IHI Boiler Management Systems
Integrated boiler control and monitoring units for steam generation in power plants and industrial facilities. Typical failures involve pressure transmitter errors, feedwater control valve issues, flame scanner degradation, and logic solver faults.
IHI Power Plant Instrumentation
Precision measurement and control modules for temperature, pressure, and flow monitoring in thermal and combined cycle plants. Repair focuses on analog signal conditioning, transmitter calibration drift, I/O module failures, and field instrument interfacing.
IHI Exhaust Gas Treatment Systems
Environmental control electronics for SCR and selective catalytic reduction operations in power generation. Common faults include ammonia injection control failure, temperature sensor malfunction, and DEF quality monitoring errors.
IHI Rotating Equipment Protection
Condition monitoring and vibration analysis systems for turbines, compressors, and pumps in industrial plants. Failures typically involve accelerometer signal loss, bearing temperature sensor faults, and data acquisition card issues.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common IHI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in IHI equipment arriving at our workshop.
- ✓Flame Failure Detection Sensor Malfunction — IHI flame scanner tubes (UV or IR based) accumulate soot and carbon deposits in combustion environments, reducing signal strength below detection threshold. Electrode oxidation and ceramic window contamination are primary causes of premature failure.
- ✓Fuel Control Valve Hunting and Oscillation — IHI fuel control units exhibit hunting behavior due to proportional valve spool wear, internal leakage in hydraulic circuits, or PID tuning parameter drift. Control signal ripple from power supply interference worsens oscillation in thermal load-following mode.
- ✓Combustion Control Loop Instability — IHI combustion modules suffer feedback lag when oxygen trim sensors are fouled or slow-responding. Fuel-air ratio mismatch and air register position sensor errors cause continuous oscillation between rich and lean combustion states.
- ✓Temperature Transmitter Calibration Drift — IHI RTD and thermocouple transmitters in high-temperature sections (exhaust gas, steam) experience calibration shift due to connector corrosion, reference junction contamination, and sensor drift from thermal cycling stress.
- ✓Pressure Transducer Signal Loss or Dropout — IHI pressure transducers connected to high-vibration locations (compressor discharge, turbine bearing) suffer from connector fatigue and internal solder joint cracks. Diaphragm flexure from pressure cycling causes micro-fractures in strain gauge elements.
- ✓DCS and Logic Solver Card Faults — IHI modular DCS and safety logic solver cards experience component failure from thermal cycling in engine room environments, capacitor aging in unregulated power supplies, and edge connector oxidation from humidity and salt air ingress.

Frequently Asked Questions — IHI Repairs
Do you repair IHI equipment anywhere in India?+
Yes. Synchronics repairs the complete IHI industrial equipment range — gas turbine controls, boiler management systems, power plant instrumentation, and rotating machinery protection modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all other major cities. All repairs are handled at our fully equipped facility in Vadodara, Gujarat with TAT of 5-7 working days for most repairs.
What is your experience with IHI gas turbine control system repairs?+
Synchronics has repaired IHI GECS series and turbine EHC (Electrohydraulic Control) systems for 25+ years. We specialize in combustion control tuning, fuel valve response calibration, flame safety system diagnostics, and pressure control loop optimization. Our engineers are trained on IHI proprietary fuel control algorithms and have successfully restored operability to power plants across Gujarat, Maharashtra, Rajasthan, and Tamil Nadu.
How do you handle IHI boiler safeguard system failures?+
IHI boiler safeguard and combustion control modules require precise sensor interfacing and logic sequencing. Synchronics diagnoses flame scanner signal quality, tests fuel shutoff valve response time, verifies pressure transmitter accuracy, and validates the complete safety shutdown logic. We perform full functional testing using gas burner simulators before returning equipment to thermal power stations and industrial boilers.
Can you calibrate IHI pressure and temperature transmitters to Indian industry standards?+
Yes. Synchronics maintains certified calibration standards traceable to NABL and ISO 17025. We calibrate IHI transmitters and transducers to customer specifications using precision reference instruments. We document all calibration data and provide ISO-compliant certificates suitable for power plant and refinery quality assurance requirements in India.
What warranty do you provide on IHI equipment repairs?+
Synchronics offers 12 months comprehensive warranty on all IHI repairs covering component failures and control system faults. We provide spares support and priority turnaround for warranty claims. Extended warranty options are available for critical turbine control and boiler safeguard systems serving Indian power generation facilities.
How do I send my IHI 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 IHI 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 IHI 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 IHI 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.
