INDUTHERM Product Lines We Repair
Our engineers are trained on the full INDUTHERM product range. Below are the major product families we service.
Indutherm Power Supply Units (PSU)
High-frequency power supplies (10-100 kW) generating 1-10 MHz induction energy for melting non-ferrous metals. Common faults include resonance drift, capacitor bank failure, and IGBT switching module breakdown due to thermal cycling.
Indutherm Crucible Furnace Controllers
Embedded control systems managing temperature feedback, power ramp profiles, and furnace shutdown sequences. Repairs address sensor interface faults, relay contactor wear, and PLC firmware corruption in harsh foundry environments.
Indutherm Frequency Converters and Resonance Matching
Resonant tank circuits and variable capacitor banks tuning load impedance for efficient energy transfer. Common failures include capacitor dielectric breakdown, inductor winding shorts, and vacuum relay malfunction under thermal stress.
Indutherm Temperature Monitoring & Safety Electronics
Infrared pyrometer interfaces, thermocouple acquisition modules, and alarm logic circuits preventing crucible overheat and furnace damage. Repairs include sensor linearization, cold-junction compensation circuit fixes, and relay logic board rework.
Indutherm Induction Coil & Load Matching Systems
Custom-wound induction coils and load-matching networks delivering concentrated RF energy to crucible charges. Failures stem from water cooling channel blockage detection loss, coil insulation breakdown, and impedance sensor circuit drift.

Common INDUTHERM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INDUTHERM equipment arriving at our workshop.
- ✓Indutherm Power Supply Loss and No Output — IGBT switching module thermal failure due to inadequate heatsink cooling or aged thermal compound separation. Resonant circuit feedback loss causes oscillation collapse. High-frequency transformer core saturation and winding insulation breakdown.
- ✓Furnace Temperature Overshoot and Runaway Heating — Pyrometer sensor failure or optical window fouling prevents accurate temperature feedback. PLC temperature setpoint logic corrupted by power supply noise injection. Control relay chatter under harmonic distortion from adjacent induction loads.
- ✓Intermittent Resonance Loss and Frequency Drift — Variable capacitor bank tuning network vacuum relays arcing or sticking due to RF voltage spikes exceeding nominal ratings. Impedance matching sensor calibration drift causes mistuned tank circuits. Load inductance variation (crucible charge density changes) without automatic compensation.
- ✓High-Voltage Capacitor Bank Failure and Energy Loss — Electrolytic and power film capacitors age and dry out in high-temperature foundry ambient (40-50degC continuous). Voltage spikes during power supply switching stress capacitor dielectric. Inadequate ventilation and dust ingress accelerates degradation across multiple banks in parallel configuration.
- ✓Water-Cooled Induction Coil Temperature Rise and Thermal Shutdown — Internal scale and mineral deposit blockage in coil cooling channels reduces coolant flow. Thermistor or temperature switch calibration drift causes false overheat alarms. Cooling pump bearing wear or impeller cavitation reduces flow pressure on demand-side.
- ✓PLC Firmware Corruption and Loss of Furnace Control Logic — Power supply transients during mains switching or equipment fault cascade corrupt flash memory cells. Outdated firmware lacking immunity to electrical noise or containing incompatible parameter sets. Accidental parameter overwrite during commissioning or technician error.

Frequently Asked Questions — INDUTHERM Repairs
Do you repair Indutherm equipment anywhere in India?+
Yes, Synchronics repairs the full Indutherm product range across India. We maintain expertise in power supply units, crucible furnace controllers, frequency converters, and induction coil systems. We offer PAN India pickup and delivery from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and Kolkata. All repairs are completed at our Vadodara, Gujarat facility with genuine Indutherm spare parts and factory-calibrated test equipment.
What is the typical turnaround time for Indutherm power supply repair?+
Standard Indutherm power supply diagnosis and repair averages 5-7 working days at Synchronics. Express repair of capacitor bank or IGBT module replacement can be completed in 2-3 days if parts are in stock. Critical furnace downtime situations are prioritised. We ship repaired units with comprehensive test certificates confirming output power, resonance frequency stability, and thermal performance.
How do you diagnose Indutherm frequency drift and resonance loss issues?+
Synchronics uses impedance analysers, network analysers, and high-frequency load banks to measure resonant circuit Q-factor, capacitor tuning precision, and frequency stability across full power range. We simulate actual crucible loads and verify automatic impedance matching compensation. Vacuum relay contact resistance is measured with milliohm meters. Software logic for resonance feedback control is verified against original Indutherm firmware specifications. Root cause analysis identifies whether failure is capacitor aging, relay stiction, or sensor drift.
Can Synchronics upgrade older Indutherm furnace controllers to modern safety standards?+
Yes. Synchronics offers controlled modernisation of legacy Indutherm control systems. We can retrofit updated PLC firmware with enhanced temperature control algorithms, improved noise immunity, and expanded alarm logging. Safety relay modules can be upgraded to current industrial standards (dual-channel architecture, fail-safe logic). However, major upgrades require Indutherm technical approval. We recommend phased approaches: repair legacy units for continued service life, then plan replacement with modern Indutherm systems or compatible alternatives as foundry production strategy allows.
What documentation and spare parts inventory does Synchronics maintain for Indutherm?+
Synchronics maintains comprehensive Indutherm technical manuals, circuit diagrams, calibration procedures, and firmware repositories covering power supplies from 10 kW to 100 kW range and legacy to current production models. We stock critical spare parts including IGBT modules, power film capacitors (rated for high-frequency ripple current), vacuum relays, induction coil assemblies, and sensor modules. Parts procurement from Germany-based distributors ensures genuine Indutherm quality. Long-term service agreements with major foundries include quarterly spare parts availability planning.
How do I send my INDUTHERM 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 INDUTHERM 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 INDUTHERM 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 INDUTHERM 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.
