Specialist ETA thermal system diagnostics and precision repairs for Indian industry.
ETA Product Lines We Repair
Our engineers are trained on the full ETA product range. Below are the major product families we service.
ETA Immersion Heater Systems
Electric immersion heaters for water heating, oil temperature control, and process fluid conditioning. Common faults include heating element burnout, thermostat failure, scale buildup affecting efficiency, and electrical connection degradation in high-humidity environments.
ETA Thermostatic Expansion Valve (TEV) Systems
Precision thermal regulation valves for refrigeration and thermal management loops. Failures typically stem from bulb sensor malfunction, valve seat erosion from contamination, or thermal lag under rapid load changes in industrial cooling circuits.
ETA Temperature Control Panels
Industrial control panels with integrated PID temperature controllers, solid-state relays (SSR), and safety cut-outs for batch processing and continuous heating operations. Faults include relay sticking, sensor signal loss, calibration drift, and PLC communication failures.
ETA Thermal Flow Control Devices
Precision flow regulation and mixing valves for hot water circuits, heat exchanger systems, and thermal recovery loops. Common issues include valve clogging from scale or particulate contamination, actuator seal wear, and pressure differential instability.
ETA Safety & Limit Controls
Over-temperature switches, low-level cut-outs, and pressure relief controllers protecting thermal systems from dangerous conditions. Failures occur due to sensor contact corrosion, mechanical linkage wear, or setpoint drift after prolonged operation.

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 ETA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ETA equipment arriving at our workshop.
- ✓Immersion heater element failure or burnout — Sheath corrosion, mineral scale accumulation reducing heat transfer, or manufacturing defects in the nichrome wire causing hot spots. Indian hard-water regions accelerate scale buildup, reducing element lifespan.
- ✓Thermostat bulb sensor loss of sensitivity — Refrigerant or thermal fluid leakage from the sensing bulb, separation of the liquid/gas interface inside the bulb, or sensor isolation from the process stream due to fouling or pipe blockage.
- ✓Control panel PLC or relay malfunction — Solid-state relay (SSR) gate driver failure from thermal cycling, PLC input card burnout due to voltage spike, or electrolytic capacitor aging in power supplies exposed to high ambient temperatures common in Indian manufacturing plants.
- ✓Temperature sensor drift or loss of signal — RTD (Pt100/Pt1000) wiring corrosion in steam or high-humidity environments, thermocouple cold-junction compensation circuit failure, or sensor blockage by process fluid sediment. Indian coastal industrial areas see accelerated sensor corrosion.
- ✓Valve actuator sticking or slow response — Sludge or mineral buildup in valve seat and ball surfaces, corrosion of the piston rod inside the actuator housing, or loss of hydraulic/pneumatic pressure in actuation circuits due to seal wear or line blockage.
- ✓Over-temperature safety switch nuisance trips — Setpoint drift due to thermal cycling, mechanical wear of the bimetallic strip or contact spring, or sensor location giving false readings due to process turbulence or inadequate immersion depth in the bulk fluid.

Frequently Asked Questions — ETA Repairs
Do you repair ETA equipment anywhere in India?+
Yes. Synchronics repairs the full ETA thermal control and heating systems product range across India. We offer PAN India door-to-door pickup and return logistics from all major cities — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Lucknow, Jaipur, and beyond. Our central repair facility in Vadodara, Gujarat, ensures fast turnaround and consistent quality. Contact us for a free diagnostic quote.
What is the typical turnaround time for ETA immersion heater repair?+
Standard ETA heater element replacement and testing takes 5-7 working days. Complex multi-element assemblies or custom thermal management systems may require 10-14 days depending on spare parts availability and required certifications (e.g. pressure vessel compliance). Synchronics provides daily progress updates and offers express service for critical production scenarios.
Can you repair ETA expansion valves that have lost refrigerant charge?+
Yes. Synchronics performs full ETA thermostatic expansion valve rehabilitation — including leak detection with tracer dye, replacement of corroded or damaged sensing bulbs, re-charging with the correct refrigerant grade (R404A, R134a, or R22 as specified), and pressure-test verification. We use OEM ETA components and calibrate setpoints to match your process requirements.
Do you stock ETA spare parts and thermal sensors?+
Yes. Synchronics maintains a stock of common ETA replacement parts — immersion heater elements, RTD and thermocouple sensors, solenoid coils, relay cards, and safety switch assemblies. We also source hard-to-find components through our ETA distributor network across Europe and India. Lead times are typically 3-5 working days for OEM parts.
Can you help with ETA thermal system commissioning and calibration after repair?+
Yes. Beyond repair, Synchronics offers on-site or facility-based calibration of ETA temperature controllers, expansion valves, and safety limits. We use certified reference instruments, provide calibration certificates traceable to ISO standards, and conduct witness testing to verify performance in your process environment. This ensures your system meets pharmaceutical GMP, food safety, or chemical industry compliance requirements.
How do I send my ETA 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 ETA 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 ETA 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 ETA 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.
