CHIYODA Product Lines We Repair
Our engineers are trained on the full CHIYODA product range. Below are the major product families we service.
Chiyoda Air Coolers & Finned Tube Heat Exchangers
Robust air-cooled condensers and shell-and-tube exchangers for power plants and refineries. Common issues include tube fouling, fin corrosion, fan motor failures, and temperature control malfunction due to mineral deposits in Indian hard water applications.
Chiyoda Thermostatic Expansion Valves (TEV) & Control Instrumentation
Precision temperature and pressure regulators for refrigeration and thermal loops. Failures include valve stiction from contamination, sensing bulb leaks, solenoid coil burnout, and electronic controller display failures common in high-vibration plant environments.
Chiyoda Condenser & Cooler Temperature Controllers
Standalone and integrated PLC-based thermal management systems for process cooling. Issues stem from PT100/PT1000 RTD sensor drift, relay contact erosion, power supply ripple, and firmware glitches in humid coastal Indian facilities.
Chiyoda Pressure & Flow Monitoring Systems
4-20mA transmitters and pressure gauges integrated with Chiyoda exchangers. Common faults include transducer calibration drift, 4-20mA signal noise from VFD interference, pressure relief valve creep, and connector corrosion in salt-laden atmospheres.
Chiyoda Cooling Tower Integration & Control Panels
Combined heat exchanger and cooling tower orchestration panels for large thermal loops. Failures include contactor sticking, variable frequency drive (VFD) faults, thermostat calibration loss, and circuit board solder joint cracking from thermal cycling stress.

Common CHIYODA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHIYODA equipment arriving at our workshop.
- ✓Chiyoda thermostat display blank or erratic readings — Caused by cracked LCD display due to thermal cycling, failed power supply rectifier, or corroded battery backup terminals in coastal/humid Indian plants. PT100 sensor disconnection is also common.
- ✓TEV (thermostatic expansion valve) stuck closed, no cooling flow — Mineral scale buildup or corrosion debris inside Chiyoda valves from hard water or contaminated refrigerant. Sensing bulb rupture or solenoid winding short-circuit prevents proper valve actuation in Indian industrial water loops.
- ✓4-20mA signal noise on Chiyoda pressure transmitter, unstable readings — Electromagnetic interference (EMI) from adjacent VFDs, motor starters, or high-voltage bus bars in petrochemical and refinery environments. Poor shielding in cables or corroded connector pins cause signal degradation.
- ✓Chiyoda cooler fan motor runs continuously or not at all — Thermostat setpoint calibration loss, failed temperature sensor feedback, or overheated motor windings from dust accumulation. Capacitor degradation in the motor starter causes starting torque collapse.
- ✓Chiyoda heat exchanger leaking coolant or refrigerant from tube bundle — Corrosion perforation from galvanic coupling between dissimilar metals in hard water environments or aggressive petrochemical process fluids. Erosion-corrosion attack on tube walls under high velocity flow; scale buildup restricting flow and causing local boiling and bubble formation.
- ✓Chiyoda control panel contactor chattering or refusing to hold thermal load — Worn contactor contacts, low supply voltage, or control signal noise on the coil. Common in older Chiyoda integrated cooler panels where contactors switch at high frequency during temperature regulation cycles.

Frequently Asked Questions — CHIYODA Repairs
Do you repair Chiyoda heat exchangers and cooler control systems anywhere in India?+
Yes. Synchronics repairs the complete Chiyoda portfolio - air coolers, finned exchangers, thermostatic expansion valves, temperature controllers, and integrated cooler management panels. We operate PAN-India pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and 50+ cities. All repairs completed in our Vadodara, Gujarat facility with turnaround of 3-7 days for most Chiyoda equipment.
My Chiyoda cooler thermostatic valve is leaking refrigerant. Can you repair it, or must I replace it?+
Repair depends on the root cause. If the sensing bulb is ruptured or the solenoid coil is burned, we typically replace the entire TEV with OEM Chiyoda equivalent. If internal valve seats or spools are corroded but seals are intact, Synchronics performs precision reboring, resurfacing, and recalibration to restore full functionality at 60-70% of new replacement cost. We always flush the refrigerant loop and replace inline filters post-repair.
What is the typical turnaround time for Chiyoda pressure transmitter or RTD sensor repair?+
Most Chiyoda pressure transmitters and temperature sensors (PT100/PT1000) are replaced rather than repaired - we stock OEM equivalents and 48-hour compatible alternatives from leading suppliers. If the sensor cable, connector, or display integration is the issue, Synchronics diagnoses within 24 hours and repairs within 48 hours. Emergency same-day service is available for critical power plants and refineries across India.
How do you prevent Chiyoda heat exchanger fouling and tube corrosion failures in Indian hard water conditions?+
During annual maintenance, Synchronics recommends chemical flushing of Chiyoda tube bundles with approved inhibited hydrochloric acid or chelating agents to remove scale buildup. We install magnetic strainers upstream of the exchanger, specify water treatment to stabilize pH (6.8-7.2), and add corrosion inhibitors suitable for Chiyoda's nickel-copper or titanium tubing. Post-flush eddy-current inspection confirms tube wall thickness before the cooler returns to service. This preventive approach reduces emergency repairs by 70-80% in coastal and hard-water regions.
Can Synchronics retrofit my old Chiyoda cooler with a modern PLC-based temperature controller?+
Yes. Synchronics specializes in retrofitting legacy Chiyoda air coolers and heat exchangers with modern industrial IoT-enabled controllers featuring Modbus/TCP, data logging, and alarm email notifications. We integrate new controllers with your existing SCADA or distributed control systems (DCS) used in refineries and power plants. Retrofit cost is typically 30-40% less than a full cooler replacement, and we guarantee compatibility with your original Chiyoda tube bundle.
How do I send my CHIYODA 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 CHIYODA 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 CHIYODA 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 CHIYODA 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.
