DUO-THERM Product Lines We Repair
Our engineers are trained on the full DUO-THERM product range. Below are the major product families we service.
DUO-THERM Precision Heat Exchangers
Plate-frame and shell-tube heat exchanger systems with integrated thermostatic controls. Common repair needs include internal fouling, valve seal failure, and temperature sensor drift affecting process stability.
DUO-THERM Process Temperature Controllers
PLC-based thermal management units with multi-zone capability and analog/digital I/O for pump and heater control. Failures typically involve PID loop tuning issues, RTD input card failures, and relay contact degradation.
DUO-THERM Circulation Pump Systems
Centrifugal and gear pump assemblies rated for high-temperature fluids with thermal protection and variable speed drives. Common issues include bearing wear, impeller cavitation, and drive coupling alignment problems.
DUO-THERM Temperature Sensing Modules
RTD and thermocouple sensor assemblies with signal conditioning for industrial process control. Repair focus includes sensor cable integrity assessment, transmitter calibration drift, and connector corrosion in high-moisture environments.
DUO-THERM Thermal Load Banks
Resistive heating and cooling load simulation equipment for system commissioning and testing. Common failures involve heating element burnout, power contactor wear, and control relay intermittency.
DUO-THERM HMI Touch Panels
7-inch to 15-inch touchscreen operator interfaces with real-time thermal monitoring and alarm display. Repair challenges include LCD backlight failure, capacitive touch layer degradation, and internal processor board corrosion.

Common DUO-THERM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DUO-THERM equipment arriving at our workshop.
- ✓Temperature setpoint drift causing product quality variance — DUO-THERM controller PID calibration constants degradation over time, typically caused by sensor RTD aging or power supply voltage ripple exceeding ±5% specification. Cumulative thermal cycles degrade the precision resistor networks in analog input modules.
- ✓Circulation pump cavitation and loss of flow — Fluid inlet pressure drop below vapor pressure due to fouled intake filters, kinked suction lines, or impeller clearance degradation in DUO-THERM CP-series pumps. High-temperature operation accelerates bearing wear and radial play increase.
- ✓RTD sensor resistance reading errors and sensor faults — Lead wire corrosion in high-humidity or chemical vapor environments, connection pin oxidation at DUO-THERM sensor terminals, or platinum element integrity loss. Common in textile dyeing and bleach operations across Indian mills.
- ✓Relay coil chatter and intermittent pump/heater shutdown — Dust accumulation on DUO-THERM relay contacts causing increased contact resistance; coil insulation breakdown from moisture ingress; or control voltage supply ripple exceeding relay pull-in tolerance. Accelerated failure in vibration-prone plant locations.
- ✓HMI touchscreen unresponsive or partial display failure — LCD backlight LED aging reducing brightness to unreadable levels; capacitive touch layer contamination or delamination in DUO-THERM HMI panels; or internal processor board capacitor dry-out from prolonged high-temperature operation near heat exchangers.
- ✓Heat exchanger scaling and reduced thermal transfer efficiency — Internal calcium and magnesium carbonate deposition in DUO-THERM plate-frame exchangers due to hard water or untreated process fluids. Biofilm accumulation in circulation loops reduces effective surface area by 30-50% and increases parasitic pressure drop.

What is the typical turnaround time for DUO-THERM controller repair?+
Standard DUO-THERM process controller repair (PID tuning, relay replacement, power supply diagnostics) requires 5-7 working days including full system testing and calibration. Sensor replacement and HMI panel repair typically take 3-5 days. Urgent rush service is available for critical production downtime situations — we prioritize jobs and can complete diagnostics within 24 hours.
Can Synchronics repair legacy DUO-THERM thermal systems from the 1990s and early 2000s?+
Absolutely. We have extensive experience with all DUO-THERM product generations from analog proportional controllers through modern IoT-enabled systems. Obsolete relay modules, analog signal conditioning cards, and mechanical pump assemblies are repaired or sourced as equivalent modern replacements. We maintain technical documentation archives and can support systems that are 20-30 years old.
Do you offer preventive maintenance contracts for DUO-THERM equipment?+
Yes. Synchronics provides quarterly and semi-annual preventive maintenance programs for textile mills, chemical plants, and food processors running DUO-THERM thermal systems. Maintenance visits include sensor recalibration, controller firmware verification, heat exchanger inspection, circulation pump performance testing, and HMI touchscreen assessment. Contracts are customized for equipment criticality and operational environment.
What documentation should I send with my DUO-THERM equipment for repair assessment?+
Please provide the original DUO-THERM equipment manual or datasheet, any fault codes or error messages displayed on the HMI panel, a description of operating symptoms (temperature variance, flow loss, electrical faults), and maintenance history if available. Schematic diagrams for customized thermal control installations are helpful. Synchronics will perform comprehensive diagnostics regardless; detailed history helps expedite root cause identification.
How do I send my DUO-THERM unit for repair?+

What is the cost of repairing a DUO-THERM 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 DUO-THERM 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 DUO-THERM 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.
