Absolutely. Synchronics is certified to repair Doosan genset automatic voltage regulators (AVR) and DSNM/DSNP fuel governors used in standby and continuous-duty power plants across Indian refineries, hospitals, data centers, and telecom towers. We test AVR voltage stability, frequency response, and load-sharing accuracy. Our engineers reverse-engineer governor calibration for your specific engine speed and load profile, ensuring reliable parallel operation and grid synchronization.

Yes. Doosan air and oil compressor solenoid valves and their driver circuits are a specialty repair area for Synchronics. We diagnose stuck unload valves, thermal cutout failures, and solenoid coil burnouts. Our team performs bench testing with pressure simulators to verify pressure build-up, cutoff accuracy, and fail-safe operation. Many Indian manufacturing plants have extended compressor life by 3-5 years after our thermostatic controller recalibration.

All Doosan repairs carry a 12-month manufacturer-grade warranty covering parts and labor. We provide a detailed fault analysis report, component-level test data, and before-after performance curves. If your equipment fails within 12 months due to our repair work, Synchronics provides free re-repair or replacement. We also offer optional extended service contracts with free preventive diagnostics every 6 months, ideal for large Doosan fleets operating in Indian mining and construction sectors.
