OHKURA Equipment We Repair — By Category
OHKURA Product Lines We Repair
Our engineers are trained on the full OHKURA product range. Below are the major product families we service.
Temperature Controllers (DX/CX/EX Series)
OHKURA DX, CX, and EX series are widely deployed in Indian pharmaceutical and chemical manufacturing. Common faults include thermocouple sensor interface failures, relay contact degradation, PID tuning errors, and firmware corruption affecting temperature stability and alarm response.
Paperless Recorders (MR100/MR2100)
OHKURA paperless recorders capture multi-channel process data in regulated industries. Typical faults involve SD card read/write errors, Ethernet communication dropout, touch panel unresponsiveness, and data logging gaps caused by memory corruption or firmware glitches.
Process Control Units (PCU-D/PCU-E)
Compact process control units for batch and continuous operations. Repair needs include analog input isolation failures, digital output relay failures, network communication timeouts, and logic program execution errors affecting manufacturing sequences.
Indicator/Transmitter Modules
Panel-mount and transmitter-type indicators used in pharmaceutical validation and chemical process monitoring. Common issues are loose PCB components, sensor calibration drift, 4-20mA output instability, and digital display segment faults.
Why Choose Synchronics for OHKURA Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on OHKURA equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common OHKURA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in OHKURA equipment arriving at our workshop.
- ✓Thermocouple input signal loss or erratic readings — OHKURA temperature controller thermocouple input circuits are susceptible to cold junction compensation drift and connector corrosion in high-humidity pharmaceutical environments. Vibration in production areas causes micro-fractures in junction traces.
- ✓Relay coil failure causing loss of heating/cooling control — OHKURA controller relay coils degrade from thermal cycling and inductive load switching in chemical processing. Contactor coils burn out when pilot circuits experience voltage transients from adjacent equipment or inadequate snubber protection.
- ✓Paperless recorder Ethernet communication timeout — OHKURA MR2100 network controllers fail when industrial EMI from large motors affects RJ45 connector shielding. Firmware buffer overflow occurs when recording channels exceed CPU processing limits, dropping network packets.
- ✓Touch panel display unresponsiveness or partial segment loss — OHKURA paperless recorder capacitive touch sensors degrade from condensation and chemical vapor exposure in pharmaceutical manufacturing suites. LCD backlight failures develop when power supply capacitors dry out from sustained 40-50°C ambient temperatures.
- ✓PID control instability causing temperature overshoot and oscillation — OHKURA temperature controller PID parameters drift when sensor response changes due to aging thermocouples or fouled RTDs. Integral windup occurs in batch processes where setpoint changes are frequent without proper logic constraints.
- ✓Data logger SD card write errors and missing timestamps — OHKURA MR recorders develop SD card interface timing issues when system clock drifts due to battery aging. File system corruption occurs when power cycles interrupt write operations during data logging cycles.

Frequently Asked Questions — OHKURA Repairs
Does Synchronics repair OHKURA equipment throughout India?+
Yes. Synchronics Electronics provides comprehensive OHKURA repair across India for temperature controllers, paperless recorders, process control units, and all instrumentation models. We offer PAN India door-to-door pickup from major cities including Ahmedabad, Mumbai, Pune, Delhi, Hyderabad, Chennai, Bangalore, and Kolkata. All repairs are completed at our Vadodara facility with genuine OHKURA components and factory-calibrated testing.
How do you handle OHKURA temperature controller calibration in GMP facilities?+
Synchronics maintains GMP compliance throughout OHKURA controller repair. Thermocouple input circuits are calibrated against NIST-traceable precision standards. All calibration records, temperature accuracy verification (±0.1°C), and sensor response documentation are provided to meet FDA 21 CFR Part 11 electronic record requirements for pharmaceutical batch records.
What is the typical turnaround time for OHKURA paperless recorder repair?+
Standard OHKURA paperless recorder repair (firmware updates, Ethernet module replacement, touch panel repair) requires 5-7 working days. Emergency repairs can be prioritized to 24-48 hours for critical batch processes. We provide loaner units where available to minimize production impact during pharmaceutical validation campaigns.
Can Synchronics repair OHKURA equipment with communication protocol failures?+
Yes. Synchronics specializes in OHKURA Modbus RTU, Modbus TCP, and Ethernet communication restoration. We debug network packet loss, reprogram communication parameters, and verify data integrity with process SCADA systems. Many Indian chemical plants rely on our OHKURA gateway integration expertise for Industry 4.0 data collection systems.
Do you stock genuine OHKURA spare parts and modules?+
Synchronics maintains inventory of common OHKURA replacement modules including relay cards, input/output modules, Ethernet adapters, and sensor connectors. We source genuine components through authorized Japanese distributors to ensure compatibility and warranty protection. Custom lead-time parts are expedited within 2-3 weeks for specialized OHKURA configurations.
How do I send my OHKURA 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 OHKURA 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 OHKURA 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 OHKURA 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.
