CAPEL Product Lines We Repair
Our engineers are trained on the full CAPEL product range. Below are the major product families we service.
CAPEL Temperature Controllers (Analogue & Digital)
CAPEL's flagship range of on-off, proportional, and PID temperature controllers used in injection moulding, extrusion, and heat treatment. Common faults include loss of setpoint calibration, thermocouple input failure, and relay contact wear.
CAPEL Industrial PLC Units
Compact programmable controllers with relay outputs and analogue I/O modules for process automation. Failures typically stem from power supply degradation, input card faults, and program memory corruption.
CAPEL Digital Display & Indicator Units
LED and LCD display units for real-time temperature and process parameter monitoring. Issues include segment failure, sensor signal dropout, and communication module breakdown.
CAPEL Process Regulation Modules
Multi-zone regulation and sequential control modules for complex thermal processes in textile dyeing and pharmaceutical batch reactors. Common defects: isolation relay failure, signal conditioning circuit breakdown, firmware version incompatibility.
CAPEL Sensor & Transducer Interface Cards
Thermocouple, RTD, and 4-20mA signal conditioning modules for process integration. Repair issues include linearisation calibration loss, amplifier drift, and connector corrosion.

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 CAPEL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CAPEL equipment arriving at our workshop.
- ✓Loss of temperature setpoint calibration and drift — EEPROM memory degradation or power supply brown-out events cause stored calibration constants to corrupt, resulting in temperature readings 5-15 degrees off setpoint. This is especially common in Indian plants with unstable grid voltage (typical in Tier-2 industrial zones).
- ✓Thermocouple input signal loss or erratic readings — Cold junction compensation circuit failure, corroded thermocouple connectors, or damaged signal conditioning amplifiers on the input card. CAPEL controllers are sensitive to even millivolt-level noise on TC input lines in high-EMI environments (textile mills, foundries).
- ✓Relay contact welding or failure to switch load — CAPEL controllers rely on electromechanical relays for heater switching. Inductive load transients, age-related contact erosion, or under-rated relay coils cause contacts to weld or develop high resistance, preventing load control.
- ✓PLC program memory corruption or flash failure — Power interruption during firmware upload, defective flash memory IC, or lightning strike damage to the main processor board. CAPEL PLC units lose programmed logic or fail to boot entirely.
- ✓Modbus or RS485 communication protocol errors — Faulty MAX485 transceiver chips, damaged twisted-pair communication cables, or termination resistor failure cause CAPEL networked modules to lose sync with master PLC or SCADA systems. Typical symptom: intermittent 'No Response' timeout errors.
- ✓Power supply voltage regulation failure and output ripple — Electrolytic capacitor drying (accelerated by Indian summer heat in non-air-conditioned plants), transformer core saturation, or faulty voltage regulator ICs cause CAPEL power supplies to output unstable voltage with excessive ripple, triggering erratic controller behaviour and sensor noise.

Frequently Asked Questions — CAPEL Repairs
Do you repair CAPEL equipment anywhere in India?+
Yes. Synchronics repairs the full CAPEL product range — temperature controllers, PLCs, digital displays, regulation modules, and sensor interface cards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other cities. Repairs are handled at our main facility in Vadodara, Gujarat, with turnaround typically 5-7 working days for standard faults.
What is the cost and timeline for CAPEL controller repair?+
CAPEL temperature controller repairs typically cost Rs 3,500-8,500 depending on fault complexity (calibration reset, power supply replacement, component-level repair). Standard turnaround is 5-7 days; emergency same-day diagnostics available for production-critical units. We provide free fault assessment and quotation before repair work begins. All parts carry 12-month warranty.
Can you repair CAPEL equipment without original circuit diagrams or software?+
Yes. Synchronics maintains a library of CAPEL technical documentation and firmware for all common models (CAPEL 8000, 3000, 4000, PLC-16, PLC-32, etc). Our engineers reverse-engineer circuits when documentation is unavailable, using curve tracing and signal injection testing. If customer has original program backups, we can restore them; otherwise we provide factory-default firmware.
Why are my CAPEL temperature readings drifting despite recalibration?+
Temperature drift in CAPEL controllers typically indicates either thermocouple connector corrosion, signal conditioning amplifier failure, or power supply regulation problems. High-EMI environments (textile mills, foundries) can also introduce sensor noise. Synchronics performs three-point thermal calibration validation against precision reference sensors and tests in your application environment to root-cause drift. We also upgrade your thermocouple wiring and add shielding if environmental noise is the culprit.
Do you stock spare parts for CAPEL equipment?+
Synchronics maintains inventory of common CAPEL replacement modules including power supplies, relay cards, RS485 transceiver modules, input/output cards, and electrolytic capacitors. For older CAPEL models, we source components through authorised French distributors or use functionally equivalent replacements with full compatibility testing. Lead time for special components is typically 10-14 days.
How do I send my CAPEL 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 CAPEL 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 CAPEL 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 CAPEL 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.
