INDUCTOTHERM Product Lines We Repair
Our engineers are trained on the full INDUCTOTHERM product range. Below are the major product families we service.
Inductotherm Power Supply Systems (PSU)
High-frequency and intermediate-frequency induction power supplies (10 kW to 5 MW) for melting ferrous and non-ferrous metals. Common faults include SCR rectifier failures, capacitor bank degradation, and control board malfunctions under thermal stress.
Inductotherm Frequency Converters
Solid-state frequency conversion systems that transform 50 Hz industrial supply to 400+ Hz for efficient coupling coil operation. Prone to IGBT switching failures, DC link instability, and harmonic distortion issues in power-constrained Indian facilities.
Inductotherm Temperature and Level Control Systems
Programmable logic controllers and operator interfaces for real-time melt temperature monitoring and crucible level indication. Failures include sensor interface errors, thermocouple input card shorts, and HMI display malfunctions.
Inductotherm Crucible and Coil Systems
Electromagnetic coupling systems and refractory-lined crucibles integrated with power delivery electronics. Control electronics failures can occur due to high-frequency stress, thermal cycling, and moisture ingress in humid Indian foundry environments.
Inductotherm Thyristor and SCR Modules
High-current silicon-controlled rectifier (SCR) and thyristor stacks for power rectification in melting circuits. These fail due to gate drive failures, junction thermal runaway, and snubber circuit degradation under sustained 200+ amp operation.
Inductotherm Transformer and Coupling Systems
Step-down transformers and impedance matching coupling units connecting primary supply to induction work coils. Failures include winding insulation breakdown, core saturation, and secondary winding shorts from coil proximity faults.

Common INDUCTOTHERM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INDUCTOTHERM equipment arriving at our workshop.
- ✓SCR Rectifier Gate Drive Failure — Inductotherm SCR stacks operate at 200-400 amps continuously. Gate drive circuits fail when opto-coupler optoisolators degrade from thermal stress, flux capacitor leakage, or snubber diode reverse leakage. High ambient temperature in foundry floors accelerates failure.
- ✓DC Link Capacitor Bank Swelling and Leakage — Inductotherm power supplies use large electrolytic DC link capacitors (400+ uF at 600V) prone to electrolyte evaporation in 40-45°C foundry environments. Ripple current stress and voltage spikes from coil switching accelerate dielectric breakdown.
- ✓Frequency Converter IGBT Module Catastrophic Failure — Inductotherm IGBT modules (VFI-C, VFI-D series) fail when switching losses exceed cooling capacity or thermal cycling induces solder joint cracks. Inadequate power supply earthing in Indian facilities introduces dV/dt noise that damages gate oxide.
- ✓PLC Input Module Thermocouple Card Short Circuit — Inductotherm temperature controllers use isolated thermocouple input cards. Moisture ingress, cold solder joints, and flux residue create galvanic shorts between thermocouple pairs and ground, causing temperature reading failure and furnace shutdown.
- ✓Coil Coupling Frequency Mismatch and Power Loss — Inductotherm frequency converters must maintain lock with work coil resonance. Coil damage, water cooling jacket leaks, or soft-start module drifts cause frequency deviation, reducing coupling efficiency from 85% to <60% and overheating the coil.
- ✓HMI Display and Operator Panel Communication Loss — Inductotherm PLC systems communicate with touchscreen HMIs via RS-485 or Ethernet. Corrosion in connector pins, ground loop noise, and firmware version mismatch cause intermittent data loss, preventing operators from adjusting melt temperature or crucible level.

Frequently Asked Questions — INDUCTOTHERM Repairs
Do you repair Inductotherm equipment anywhere in India?+
Yes. Synchronics repairs the full Inductotherm product range — induction power supplies, frequency converters, PLC control modules, and coupling systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other cities. Repairs are completed in our Vadodara, Gujarat facility with 180+ engineers and full test benches.
What is the typical turnaround time for Inductotherm power supply repair?+
Routine Inductotherm repairs (gate drive replacement, capacitor bank swap, HMI display repair) are completed in 5-7 working days. Complex SCR stack rebuilds or frequency converter IGBT replacement may require 10-14 days. Synchronics prioritizes high-urgency repairs and offers expedited service for foundries running tight production schedules. We provide daily repair status updates.
How do you diagnose a failing Inductotherm frequency converter (VFI-C or VFI-D series)?+
Synchronics uses Inductotherm's proprietary diagnostic interface to read fault codes and monitor real-time switching frequency, load current, and thermal sensor data. We perform component-level testing of IGBT modules under load simulation and measure dV/dt immunity. If soft-start modules are suspect, we swap them with known-good units and retest. Gate drive oscilloscope traces are captured to verify gate voltage waveforms match Inductotherm specifications.
Can Synchronics source genuine Inductotherm spare parts for old systems no longer in production?+
Yes. Synchronics maintains relationships with Inductotherm authorized distributors and legacy parts suppliers across India and USA. For obsolete SCR stacks, capacitor banks, or control boards, we identify equivalent high-reliability industrial components tested and validated as form-fit-function replacements. We provide 12-month warranty on all refurbished Inductotherm systems and spare parts.
What preventive maintenance protocols do you recommend for Inductotherm induction melting systems?+
Synchronics recommends quarterly inspection of DC link capacitors (visual swelling, ESR measurement), semi-annual gate drive optocoupler testing, and annual frequency converter soft-start module calibration. In humid Indian coastal facilities, conformal coating of PLC input cards every 18 months extends component life. We provide on-site PM contracts with diagnostic testing and spare parts supply for foundries seeking zero-downtime operations.
How do I send my INDUCTOTHERM 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 INDUCTOTHERM 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 INDUCTOTHERM 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 INDUCTOTHERM 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.
