DUN-RITE PRODUCTS Product Lines We Repair
Our engineers are trained on the full DUN-RITE PRODUCTS product range. Below are the major product families we service.
DUN-RITE Motor Control Centers (MCC)
Industrial-grade motor starter assemblies with integrated overload protection, soft-start modules, and power factor correction. Common repairs include contactor failures, thermal overload relay calibration drift, and starter coil burnout in high-ambient Indian manufacturing environments.
DUN-RITE Process Control Units (PCU)
Dedicated controllers for continuous industrial processes including temperature, pressure, and flow regulation. Frequent faults involve analog input module degradation, output relay sticking, and firmware corruption in harsh plant conditions.
DUN-RITE Automation Interface Modules (AIM)
I/O expansion and protocol conversion units linking legacy equipment to modern SCADA and PLC networks. Typical failures include terminal block corrosion, isolation relay malfunction, and communication protocol timeout errors.
DUN-RITE Power Distribution Panels (PDP)
Enclosed distribution and branch circuit protection systems for industrial plants. Common issues include bus bar oxidation, breaker tripping inconsistency, and ground fault detector sensitivity drift in high-humidity mill environments.
DUN-RITE Soft Starter Modules (SSM)
Electronic motor acceleration controllers reducing mechanical stress and inrush current on Indian manufacturing lines. Repair needs include thyristor gate drive circuit failure, current sense resistor burnout, and cooling fan motor seizure.
DUN-RITE Industrial Instrumentation Transmitters (IIT)
Analog signal conditioning and transmitter units for process measurement in cement, steel, chemical, and textile plants. Typical failures include 4-20mA loop instability, sensor calibration drift, and connector pin oxidation.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common DUN-RITE PRODUCTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DUN-RITE PRODUCTS equipment arriving at our workshop.
- ✓Motor contactor coil burnout on DUN-RITE MCC — Sustained voltage spikes from switching transients or loose control circuit connections common in Indian industrial plants with aging electrical infrastructure. DUN-RITE coils lack surge suppression in older MCC-3000 series units.
- ✓PCU thermal overload relay false tripping — DUN-RITE process control units experience cumulative calibration drift due to ambient temperature extremes (40-50C in Indian plants) and continuous duty cycles. Relay bimetallic strips lose sensitivity over 3-5 years.
- ✓AIM module protocol timeout or CRC errors — DUN-RITE Automation Interface Modules fail when communication buses accumulate electrical noise from VFD harmonic injection or improper shielding in crowded Indian control cabinets. Microcontroller firmware becomes unstable.
- ✓PDP bus bar oxidation and volt drop increase — DUN-RITE Power Distribution Panels suffer rapid copper oxidation in salt-laden coastal Indian plants (Maharashtra, Gujarat) and humid textile mill environments (Tamil Nadu). Aluminum hardware corrodes faster than expected.
- ✓SSM soft starter thyristor gate drive failure — DUN-RITE Soft Starter Modules experience gate drive chip failures when power supply ripple exceeds 50V peak (common in plants with weak incoming utility supply or defective UPS systems). Optoisolator circuits degrade rapidly.
- ✓IIT transmitter 4-20mA loop instability or zero drift — DUN-RITE Industrial Instrumentation Transmitters develop internal calibration drift when exposed to vibration-induced internal solder joint cracking (common on Indian textile machinery and cement kiln feeders). Reference voltage regulator aging also causes zero offset.

Emergency express service is available within 48 hours for critical plant breakdowns. We maintain inventory of common DUN-RITE replacement modules to minimize customer downtime and provide emergency loaner units when needed.
Can Synchronics repair older DUN-RITE PRODUCTS equipment from the 1990s?+
Absolutely. Synchronics specializes in legacy DUN-RITE PRODUCTS restoration including vintage MCC-3000 series frames, PCU-100 controllers, and original AIM modules. We have technical documentation, schematic libraries, and cross-reference catalogs enabling sourcing of obsolete components. Many Indian textile mills and cement plants rely on 20-30 year old DUN-RITE equipment that we keep operational through component engineering and strategic upgrades.
Does DUN-RITE PRODUCTS soft starter repair include thyristor testing and replacement?+
Yes. Synchronics performs destructive and non-destructive testing of DUN-RITE SSM thyristors using specialized curve-tracer equipment, identifies gate drive circuit failures, and performs complete power semiconductor replacement. We test repaired modules at rated current under programmable load to verify gate turn-on/turn-off performance before customer delivery, ensuring reliable soft-start performance on Indian industrial motors.
What warranty does Synchronics provide on DUN-RITE PRODUCTS repairs?+
All DUN-RITE PRODUCTS repairs carry 12-month parts and labor warranty covering defects in workmanship and component failure. We provide detailed repair certificates documenting original fault diagnosis, components replaced, test results, and performance specifications. Extended warranty options are available for mission-critical equipment in Indian manufacturing plants where downtime carries high operational cost.
How do I send my DUN-RITE PRODUCTS 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 DUN-RITE PRODUCTS 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 DUN-RITE PRODUCTS 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.
