CHY Product Lines We Repair
Our engineers are trained on the full CHY product range. Below are the major product families we service.
CHY Digital Temperature Controllers (DTC-100, DTC-200, DTC-300 Series)
Microprocessor-based PID controllers with 4-20mA input, relay or SSR output for industrial ovens, extruders, and autoclaves. Common faults: display panel failure, sensor input malfunction, relay contact wear.
CHY Resistance Heating Elements (CHY-RH and CHY-FH Series)
Tubular and flat cartridge heaters rated 1kW to 15kW for injection molding, thermoforming, and heat treatment applications. Failures include element burnout, terminal corrosion, and mechanical fracture under thermal cycling.
CHY Temperature Transmitters (TT-PT100, TT-TC Series)
4-20mA output transmitters with Pt100 RTD or K-type thermocouple inputs for remote temperature monitoring. Typical issues: drift in calibration, connector oxidation, input circuit failure.
CHY Solid State Relay Modules (SSR-10A to SSR-60A)
Thyristor-based SSR units with 3-32VDC control input and 24-480VAC load switching for precise heating power modulation. Failure modes: gate drive circuit degradation, internal thyristor short, heat sink thermal failure.
CHY Control Panel Assemblies (CPA-1000, CPA-2000 Series)
Complete integrated thermal control cabinets with contactor, overload relay, timer, and indicator lamps for production floor heating systems. Common problems: loose terminal connections, capacitor failure, fuse blowing.
CHY Process Alarm Modules (PAM-100 Series)
Standalone or plug-in alarm units with high/low temperature set-point logic, buzzer output, and relay action. Issues include sensor input failure, relay contact sticking, display malfunction.

Common CHY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHY equipment arriving at our workshop.
- ✓CHY DTC display shows locked segments or no readout — LCD panel degradation due to humidity ingress or internal solder joint fracture on the display driver PCB. Common in humid textile and food processing plants near steam sources.
- ✓CHY temperature controller reading drifts 5-15°C above actual setpoint — Pt100 RTD sensor calibration drift or internal reference voltage shift in the input conditioning circuit, especially after thermal cycling in injection molding applications.
- ✓CHY SSR module fails to switch — heating element remains cold — Gate drive circuit failure or internal thyristor junction degradation due to load surge or ambient temperature spikes beyond rated 60°C operating range.
- ✓CHY heating element burns out prematurely after 6-12 months — Excessive current draw due to improper element selection for actual load resistance, or internal material defect. Common in plastic extrusion where amperage creep occurs.
- ✓CHY temperature transmitter output stuck at 4mA or 20mA regardless of sensor input — Broken RTD sensor or thermocouple wire, or transmitter input circuit failure. Can also be caused by connector pin corrosion in wet plant environments.
- ✓CHY control panel repeatedly blows fuses or trips thermal overload — Short circuit in contactor coil or heating element circuit, failed capacitor creating inrush current spikes, or undersized fuse rating for actual connected load.

Frequently Asked Questions — CHY Repairs
Do you repair CHY equipment anywhere in India?+
Yes. Synchronics repairs the full CHY heating control and element portfolio — temperature controllers, RTD transmitters, solid-state relays, and complete control panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, Surat, Kolkata, and all tier-2 cities. All repairs are handled at our main facility in Vadodara, Gujarat within 5-7 working days.
Can you calibrate and re-range CHY temperature controllers for different sensor types?+
Absolutely. Synchronics re-programs CHY DTC series controllers for Pt100, Pt1000, K-type thermocouples, and J-type sensors. We adjust input span, decimal point placement, and alarm setpoints using our precision calibration lab. Full calibration certificate with traceability to national standards is provided.
What is the typical repair cost for a failed CHY heating element?+
CHY cartridge heater replacement ranges from Rs 800 to Rs 3500 depending on wattage (1kW to 15kW) and delivery time. Our service charge is Rs 300. We stock OEM-equivalent elements for common sizes and offer expedited replacement within 24-48 hours for urgent production needs across Indian plants.
Does Synchronics offer preventive maintenance contracts for CHY equipment?+
Yes. We offer quarterly and semi-annual CHY maintenance packages covering sensor calibration verification, SSR thermal imaging, element resistance testing, and control panel cleaning. Contracts are tailored for textile mills, plastic processors, and pharmaceutical facilities. Contact our Vadodara office for customized AMC quotes.
Can you repair CHY SSR modules that have failed under high ambient temperature conditions?+
Yes. We replace the thyristor array, upgrade heat sink thermal interface with thermal pads rated for 100°C ambient, and install gate drive protection circuits to prevent thermal runaway. Enhanced modules are tested in our 80°C environmental chamber before return shipment.
How do I send my CHY 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 CHY 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 CHY 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 CHY 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.
