GASTECH Product Lines We Repair
Our engineers are trained on the full GASTECH product range. Below are the major product families we service.
GASTECH Flame Detection Systems
UV/IR flame detectors for furnace and burner safety control. Common issues include UV tube degradation, photodiode failure, sensitivity drift in dusty environments, and false flame signals from arc welding interference.
GASTECH Oxygen & Lambda Analyzers
Zirconia oxide sensor analyzers for furnace O2 measurement and combustion control. Repair focuses on sensor aging, temperature sensor failures, Pt electrode corrosion, amplifier card faults, and calibration drift.
GASTECH Safety Controllers
Programmable safety modules for burner management and flame safeguarding interlocks. Common failures include relay module burnout, signal conditioning card short-circuits, firmware corruption, and sensor input board degradation.
GASTECH NOx & Emission Analyzers
Chemiluminescent and electrochemical NOx sensors for stack emissions monitoring and regulatory compliance. Issues include reagent pump failures, zero/span calibration loss, and contamination of sampling lines.
GASTECH Pressure & Temperature Transmitters
Smart transmitters for combustion control feedback and safety interlocks. Common problems are diaphragm rupture, 4-20mA output failures, and connector corrosion in harsh furnace environments.
GASTECH Sensor Interface & Amplifier Cards
Signal conditioning, amplification, and filtering modules for flame and gas sensors. Typical failures are capacitor leakage, op-amp burnout from electrical spikes, and PCB trace corrosion from vibration and humidity.

Common GASTECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GASTECH equipment arriving at our workshop.
- ✓UV tube dark and flame signal loss — GASTECH flame detectors use UV photomultiplier tubes that degrade over 2-3 years in high-temperature furnace environments. Tube darkening reduces light transmission and causes false flame-out trips, especially in refineries and power plants running continuous duty.
- ✓O2 analyzer sensor aging and output drift — GASTECH zirconia oxygen sensors lose sensitivity over time due to platinum electrode poisoning from fuel impurities and thermal stress. The Nernst cell voltage drifts, causing furnace O2 control to hunt or run rich, wasting fuel and increasing emissions.
- ✓Safety controller relay module burning and welding — Inductive spikes from solenoid valve coils and poor grounding in Indian plant installations cause arc-over on relay contacts in GASTECH safety controllers. The flame-out or fuel cutoff relay burns or welds shut, defeating the safety interlock and risking furnace explosion.
- ✓Gas analyzer calibration loss and zero drift — GASTECH analyzers (NOx, O2, lambda) lose zero offset calibration when sampling lines become contaminated, condensation accumulates in sensor cells, or pressure transducers fail. Repeated thermal cycling in Indian summer furnace rooms accelerates drift.
- ✓False flame signal and nuisance shutdowns — Electrical noise from arc welding, VFD harmonics, or poorly shielded sensor cables interfere with GASTECH UV/IR flame detectors. Dust accumulation on lenses and aging photodiodes lower signal-to-noise ratio, triggering spurious flame-out detections in steel mills and power plants.
- ✓Amplifier card output stuck or railing — GASTECH sensor interface cards experience capacitor failure and op-amp saturation due to supply overvoltage, water ingress near cooling towers, or burst electrolytic capacitors from vibration in furnace blower mounting. Output may hang at zero or rail to 20mA, freezing control action.

Frequently Asked Questions — GASTECH Repairs
Do you repair GASTECH equipment anywhere in India?+
Yes. Synchronics repairs the full GASTECH product range - flame detectors, oxygen analyzers, NOx sensors, safety controllers, and amplifier cards. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other industrial cities. All repairs and calibration are performed at our factory in Vadodara, Gujarat, with same-day courier return.
Can you repair GASTECH flame detectors with burnt UV tubes?+
Yes. Synchronics specializes in UV/IR flame detector restoration. We replace darkened PMT tubes, clean optical coatings, and recalibrate sensitivity using test flame sources. For GASTECH FLS-1750, FLS-2500, and FLS-3000 models, we stock replacement tube assemblies and can have your detector operational within 5-7 working days.
What is the typical turnaround time for GASTECH oxygen sensor repair?+
For GASTECH LDO-2500 and LDO-3500 oxygen analyzers, turnaround is 7-10 days if the zirconia sensor element requires replacement, or 3-4 days for calibration-only drift correction. Synchronics uses GASTECH OEM sensor elements and performs high-temperature impedance testing to confirm sensor health before returning to your refinery or power plant.
Do you calibrate GASTECH analyzers to Indian regulatory standards?+
Yes. Synchronics calibrates GASTECH oxygen, NOx, and lambda analyzers to ISO 6143 and Indian Ministry of Environment protocols for stack emissions monitoring. We use certified calibration gases, document all calibration points, and issue ISO 9001-compliant calibration certificates suitable for regulatory inspections by CPCB and state pollution boards.
Can your technicians repair GASTECH safety controller relay modules on-site at my plant?+
For minor relay contact cleaning and arc suppression retrofit, yes. However, burnt relay modules and amplifier card failures require return to our Vadodara facility for component-level repair and interlock testing. We coordinate with your plant safety officer to ensure zero downtime using loaner units while your GASTECH controller is repaired.
How do I send my GASTECH 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 GASTECH 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 GASTECH 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 GASTECH 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.
