SST Equipment We Repair — By Category
SST Product Lines We Repair
Our engineers are trained on the full SST product range. Below are the major product families we service.
SST Boiler Control Systems
Advanced flame safeguard and combustion control modules for large-scale industrial boilers. Common issues include sensor drift, solenoid valve failures, and flame detection loss leading to emergency shutdowns and safety lockouts.
SST Pressure & Temperature Transmitters
4-20mA and digital output transducers for steam lines and high-temperature process monitoring. Failures typically manifest as erratic readings, zero output, or sensor drift requiring full recalibration and replacement.
SST Steam Turbine Governors
Electro-hydraulic governor systems for turbine speed and load control in power generation. Common faults include hunting behavior, oil contamination, solenoid drift, and control loop oscillation affecting electrical output stability.
SST Thermal Relief Valve Controllers
Pilot-operated pressure control electronics for steam and hot water systems. Defects include calibration loss, pilot solenoid failure, and diaphragm rupture causing uncontrolled pressure discharge and process upset.
SST PLC Thermal Modules
Modular programmable logic controllers with specialized I/O for steam plant automation. Repair focuses on analog input card failure, communication port degradation, and program memory corruption in hazardous plant environments.
SST Ultrasonic Level & Flow Instrumentation
Non-contact measurement devices for condensate tanks, feed water systems, and steam flow monitoring. Failures include transducer acoustic wear, electronics water ingress, and signal processing errors in wet steam conditions.
Why Choose Synchronics for SST Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on SST equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 SST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SST equipment arriving at our workshop.
- ✓SST Flame Detector Loss of Signal Error — UV/IR flame sensor degradation from prolonged exposure to high radiant heat, soot accumulation on optical surfaces, or aging photomultiplier tube failure. In Indian refineries running 24/7, detector windows lose clarity within 18-24 months requiring cleaning or replacement.
- ✓SST Pressure Transmitter Reading Instability — Capacitive sensor diaphragm creep, electrolyte leakage in the fill fluid, or micro-fractures in the ceramic element caused by thermal shock cycling in steam environments. Common in power plants with rapid load swings and thermal transients.
- ✓SST Boiler Control Solenoid Valve Stiction — Coking of hydraulic fluid or control oil inside the pilot solenoid cavity due to excessive heat exposure near furnace walls. Stiction prevents smooth opening-closing transitions, causing hunting oscillations and erratic combustion control feedback to the PLC.
- ✓SST Electro-Hydraulic Governor Oil Contamination — Aging servo-valve spool wear generating ferrous particles, moisture ingress from failed breather filters, or sludge buildup from long service intervals typical in Indian power stations operating without adequate preventive maintenance protocols.
- ✓SST PLC Analog Card Water Ingress and Corrosion — Condensation in damp steam plant environments causing moisture to migrate into analog input modules, leading to short circuits between 4-20mA signal traces, scaling errors, and complete I/O card failure.
- ✓SST Ultrasonic Flow Meter Signal Loss in Two-Phase Steam — Acoustic saturation and bubble scattering from wet steam (steam with moisture droplets) creating noise that overwhelms the weak reflected ultrasonic pulse, common in condensate return lines and low-quality steam outlet measurements.

Frequently Asked Questions — SST Repairs
Do you repair SST equipment anywhere in India?+
Yes. Synchronics repairs the complete SST thermal and steam system product range including boiler controls, governors, pressure transmitters, relief valve controllers, and PLC modules. We offer PAN India pickup from all major cities — Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, Chandigarh — and centralized repair at our Vadodara, Gujarat facility. Express turnaround is 48-72 hours for most SST equipment.
What SST boiler control fault codes can you diagnose and repair?+
Synchronics technicians are expert in decoding SST boiler control error codes including flame supervision failures, valve solenoid faults, pressure sensor anomalies, and combustion lockout states. We download the control system log history, perform sensor-by-sensor testing with certified instrumentation, and reprogram safety interlocks if needed. Each repair includes full code documentation and a test report showing normal operation across your control parameters.
Can you recalibrate SST pressure transmitters on-site or must we send them to Vadodara?+
Both options available. For critical plants, Synchronics deploys on-site with portable deadweight tester (0-300 bar) and pressure controller. For routine recalibration and sensor repair, units can be shipped to our Vadodara lab where we calibrate on primary standards traceable to NABL and NIST, with full calibration certificates issued. Turnaround is 5-7 working days including post-calibration pressure soak verification.
Do you stock genuine SST replacement parts and components?+
Yes. Synchronics maintains inventory of critical SST spares including flame detector elements, solenoid valve coils, pressure sensor diaphragms, electro-hydraulic servo spools, and PLC I/O modules. We source through authorized SST distributors and verify authenticity. For parts not in stock, we expedite procurement within 3-5 days. All components carry SST warranty and installation support.
How do you handle SST governor testing after electro-hydraulic servo repair?+
Post-repair, Synchronics tests SST governors on a dynamic load simulator rig that replicates actual turbine speed transients at 20-100% load steps. We verify governor response time (<500ms), steady-state speed droop (0.5-2% per design), and damping characteristics. Load acceptance and rejection tests ensure your turbine will not hunt or oscillate when connected back to the grid. Full test data is logged and provided with the repaired unit.
How do I send my SST 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 SST 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 SST 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 SST 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.
