DUCON Product Lines We Repair
Our engineers are trained on the full DUCON product range. Below are the major product families we service.
ESP (Electrostatic Precipitator) Controllers
DUCON ESP control systems manage high-voltage power supplies, corona discharge, and collection electrode efficiency. Common faults include arcing board failures, transformer secondary winding breakdown, and mains surge damage. Synchronics provides full PCB rework, high-voltage component replacement, and insulation testing.
Continuous Emissions Monitoring System (CEMS)
DUCON CEMS transmitters measure SO2, NOx, O2, and particulate matter for regulatory compliance. Faults include sensor drift, signal conditioning amplifier failure, temperature compensation errors, and data logger crashes. Synchronics recalibrates sensors and replaces analog/digital conversion boards.
Wet Scrubber Control Systems
DUCON wet scrubber electronics regulate slurry pumps, spray nozzles, and demister fans via PLC and VFD interfaces. Typical failures include corrosion-induced relay stick, analog pressure transducer saturation, and VFD harmonics tripping. Synchronics performs board cleaning, transducer replacement, and harmonic load analysis.
Baghouse Filtration Controller
DUCON baghouse systems use PLC-based pulse jet timing and differential pressure monitoring. Recurring issues include dust ingress into solenoid coils, pressure transmitter clogging, and timer relay burnout. Synchronics cleans assemblies, replaces sealed solenoids, and upgrades to digital pressure sensors.
Fan & Motor Drive Interface
DUCON variable frequency drives and soft starters power induced/forced draft fans and scrubber circulation pumps in harsh, high-temperature environments. Failures stem from thermal runaway, capacitor dry-out, and contactor coil arcing. Synchronics rebuilds power stages, replaces electrolytic capacitor banks, and performs curve tuning.
Power Supply Modules (HV & Control)
DUCON isolated DC power supplies feed instrumentation and low-voltage logic circuits in noisy industrial environments. Typical failures include magnetics saturation, optocoupler degradation, and output voltage creep under load. Synchronics rewinds transformers, replaces isolation components, and tests full load range.

Common DUCON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DUCON equipment arriving at our workshop.
- ✓ESP arcing board capacitor burst and corona loss — High-voltage electrolytic capacitors in DUCON ESP power supplies fail due to continuous 8000+ volt stress and moisture ingress from dust collector humidity. Failure rate accelerates in coastal and monsoon-prone Indian regions.
- ✓CEMS sensor output drift and zero calibration loss — DUCON continuous emissions monitoring sensors experience fouling from fly ash and acid mist. Sensor membranes degrade, causing upward drift in SO2 and NOx readings, leading to false non-compliance alerts and regulatory penalties.
- ✓Scrubber pump relay sticking and pump runaway failure — DUCON wet scrubber control relays corrode from corrosive slurry mist exposure. Dust and salt crystals form inside relay contacts, causing intermittent sticking and uncontrolled pump operation, risking overflow and equipment damage.
- ✓Baghouse solenoid coil open-circuit and pulsing failure — DUCON pulse jet solenoids accumulate dust inside coil windings, causing insulation breakdown and coil burnout. High ambient temperatures in Indian cement and steel plants accelerate winding degradation, leading to complete loss of baghouse pulse function.
- ✓Fan VFD capacitor dry-out and DC link voltage collapse — DUCON variable frequency drives powering draft fans operate at elevated case temperatures. Electrolytic capacitor banks lose capacitance over 3-5 years, causing DC link ripple, harmonic distortion, and drive shutdown during peak load.
- ✓Control power supply regulation failure and logic brownout resets — DUCON isolated DC supply modules develop shorted secondary windings or failed voltage regulators due to surge events from incoming AC mains faults. Resulting low control voltage (below 21V on 24V rails) causes PLC watchdog resets and loss of emissions data logging.

Frequently Asked Questions — DUCON Repairs
Do you repair DUCON equipment anywhere in India?+
Yes. Synchronics repairs the full DUCON product range — ESP controllers, CEMS transmitters, scrubber electronics, baghouse pulse modules, and VFD interfaces. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, Jaipur, and all other industrial cities. All work happens in our Vadodara, Gujarat facility with turnaround time of 5-7 working days for most repairs.
My DUCON ESP system is throwing repeated 'corona voltage low' faults — what's the repair cost and timeline?+
Corona voltage loss in DUCON ESP controllers usually stems from shorted capacitors in the HV power supply or failing corona transformer secondaries. Synchronics diagnoses root cause using high-voltage testing and typically replaces the affected HV board or capacitor stack. Repair cost ranges from 15,000 to 45,000 INR depending on board complexity. Timeline is 5-6 days including full voltage stress testing and insulation verification before shipment back to your plant.
Can Synchronics recalibrate my DUCON CEMS system to meet MoEF compliance standards?+
Yes. Synchronics recalibrates DUCON continuous emissions monitoring systems using certified SO2, NOx, O2, and CO reference gas blends traceable to NIST standards. Our calibration procedure follows MoEF Schedule 5 requirements for power plant and cement kiln compliance testing. We provide full calibration certificates and recommend annual recalibration to maintain continuous 24/7 regulatory compliance across Indian industrial zones.
What is your expertise with DUCON baghouse solenoid failures in cement plants?+
Cement industry baghouse systems from DUCON operate in extreme dust and high-temperature conditions. Solenoid coils fail prematurely due to dust infiltration, moisture, and thermal cycling. Synchronics has rebuilt 200+ DUCON baghouse pulse modules in Rajasthan, Gujarat, and MP cement mills. We replace worn solenoids with sealed, IP67-rated units and retrofit pulse control logic with advanced snubber circuits that reduce voltage spike stress by 40%, extending solenoid life from 3 years to 6+ years per repair cycle.
Do you stock DUCON spare parts, or do I need to source them myself?+
Synchronics stocks high-demand DUCON spare parts — HV capacitors, relay modules, solenoids, transformer coils, and power supply boards. For obsolete or long-lead DUCON components, we source directly from DUCON USA or authorized distributors in India with typical lead time of 2-4 weeks. We can also reverse-engineer failed boards and manufacture replacement PCBs in-house, eliminating costly downtime waiting for original spares from overseas.
How do I send my DUCON 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 DUCON 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 DUCON 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 DUCON 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.
