ESR Product Lines We Repair
Our engineers are trained on the full ESR product range. Below are the major product families we service.
ESR Immersion Cooling Systems
Sealed immersion cooling units for dry-type transformers and power electronics in high-density installations. Common faults include pump failure, coolant degradation, thermal sensor drift, and seal leakage causing coolant loss and temperature runaway.
ESR Oil Analysis and Condition Monitoring
Portable and online transformer oil quality diagnostic units measuring moisture, breakdown voltage, acid number, and particle contamination. Repairs focus on sensor calibration drift, display module failures, and data logging circuit faults in field-deployed units.
ESR Thermal Imaging and Temperature Profiling
Thermal cameras and non-contact temperature measurement systems for electrical switchgear, transformer tank monitoring, and high-voltage connection diagnostics. Common issues include infrared lens contamination, detector calibration loss, and analog output card failures.
ESR Coolant Filtration and Conditioning
Mobile and fixed-installation coolant purification and water removal units for transformer and reactor cooling systems. Repairs address pump motor bearing wear, filter element clogging indicators, and micron-gauge sensor failures common in 5,000+ hour service cycles.
ESR Power Distribution Thermal Mapping
Switchgear and busbar thermal profiling systems using distributed temperature sensors and central data acquisition. Faults include loose thermocouple connections, cold-junction compensation drift, and wireless transmission module dropouts in high-EMI environments.
ESR Legacy Transformer Temperature Controllers
Analog and early-digital temperature control units regulating cooling fan speed and pump operation via thermostat-based switching. Repairs involve relay contact erosion, triac failure, sensor RTD breakage, and control relay intermittent activation.

Common ESR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ESR equipment arriving at our workshop.
- ✓Immersion coolant temperature runaway and pump shutdown — ESR coolant circulation pumps fail due to seal wear, bearing deterioration, or impeller cavitation from air ingestion. Loss of flow triggers high-temperature alarm and automatic shutdown, halting equipment cooling and risking thermal damage to transformer windings or power electronics.
- ✓Oil analysis sensor drift and false moisture readings — ESR moisture sensors and dielectric breakdown probes drift from electrode contamination, salt accumulation, or calibration baseline loss after 2-3 years field service in humid Indian climates. False high readings trigger unnecessary oil replacement.
- ✓Thermal imaging camera display blackout and no temperature readout — ESR infrared detector elements degrade from moisture intrusion, optical window contamination, or detector amplifier circuit corrosion. Display module ribbon connectors also fail due to vibration in mobile thermal cart installations common in Indian steel and power plants.
- ✓Coolant filtration cart micron-gauge sensor reading zero or stuck — ESR particle counter and micron-gauge sensors on portable filtration carts become blocked by silica dust or coolant sludge, or the sensor electronics latch in error state after unexpected power loss during field operation.
- ✓Switchgear thermal array wireless dropouts and missing temperature channels — ESR distributed thermocouple assemblies in switchgear thermal mapping systems suffer loose terminal connections, broken thermocouple wire, or wireless receiver module RF interference from adjacent VFD and HVDC installations common in Indian power distribution substations.
- ✓Legacy temperature controller relay chatter and fan speed fluctuation — ESR analog temperature controllers suffer erosion of relay contacts after 15,000+ switching cycles, or triac devices fail due to inductive kickback from pump motor windings. Setpoint potentiometer also drifts from dust ingress and humidity in Indian mill environments.

Frequently Asked Questions — ESR Repairs
Do you repair ESR equipment anywhere in India?+
Yes. Synchronics repairs the full ESR thermal diagnostics, immersion cooling, and oil analysis product range. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 industrial cities. Equipment is transported to our 180-engineer facility in Vadodara, Gujarat for same-bench diagnosis and 48-72 hour repair turnaround.
How quickly can Synchronics diagnose an ESR immersion cooling pump failure?+
Synchronics performs immediate bench diagnosis within 4 hours of receiving an ESR cooling unit. We run thermal cycle tests, check flow rate under load, verify seal integrity, and perform millivolt testing on motor windings. Diagnosis cost is waived if repair is authorized. Most pump repairs (seal kit, bearing, impeller) complete within 48 hours using OEM-equivalent spare parts.
Can you recalibrate ESR moisture sensors and oil analysis probes?+
Yes. Synchronics maintains ISO 17025 traceable standard oil sets for calibrating ESR moisture sensors, dielectric breakdown testers, and acid-number probes. We recalibrate all ESR diagnostic electronics to factory baseline standards and provide calibration certificates. Typical recalibration turnaround is 24 hours, with 12-month traceability.
Do you stock OEM ESR spare parts in India?+
Synchronics maintains a strategic inventory of ESR pump seals, bearings, filter cartridges, thermocouple sensors, relay modules, and triac chips in our Vadodara warehouse. For obsolete ESR legacy components, we source equivalent international parts and validate compatibility through bench testing. Lead time is typically 3-5 days for non-stock items.
What warranty do you provide on ESR thermal imaging and sensor repairs?+
All Synchronics ESR repairs include a 12-month parts warranty and 6-month labor warranty. Critical components like infrared detectors, thermocouples, and pump assemblies are tested at 150% rated load before dispatch. We provide on-site commissioning support for large switchgear thermal arrays and immersion cooling installations to ensure seamless return to production.
How do I send my ESR 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 ESR 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 ESR 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 ESR 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.
