INDUTHERM FLS Product Lines We Repair
Our engineers are trained on the full INDUTHERM FLS product range. Below are the major product families we service.
FLS Furnace Control System
Microprocessor-based furnace management platform controlling induction coil power, temperature monitoring, and melt cycle automation. Common repairs include sensor interface failures, power regulation faults, and firmware corruption affecting melt quality and repeatability.
VTC Voltage Thyristor Control
Thyristor rectifier and power conversion module regulating AC-to-DC supply for induction coils. Failures include thyristor short-circuit, gate driver faults, and capacitor bank degradation causing voltage regulation loss and coil burnout risk.
MFC Multi-Function Controller
Integrated melt cycle sequencer with analog I/O for temperature sensors, cooling water management, and alarm signaling. Typical faults: analog input card drift, relay bank failure, and real-time clock battery depletion affecting cycle timing.
IDS Induction Drive System
Variable frequency converter for high-power induction coil energization, enabling soft-start and harmonic filtering. Common issues: IGBT module degradation, snubber capacitor failure, and encoder signal loss in frequency feedback loops.
PCS Power Conditioning System
Power factor correction and harmonic suppression unit interfacing INDUTHERM FLS melting furnaces with facility electrical networks. Repairs focus on capacitor bank restoration, reactor coil testing, and thyristor gating circuit rebuilds.
RTM Remote Temperature Monitoring
Wireless and hardwired sensor interface suite transmitting furnace temperature and coil resistance to central FLS controller. Faults include thermocouple connector corrosion, signal amplifier drift, and wireless module RF interference causing temperature oscillation.

Common INDUTHERM FLS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INDUTHERM FLS equipment arriving at our workshop.
- ✓FLS controller temperature sensor signal loss — Thermocouple break, RTD resistance bridge imbalance, or analog input module reference voltage drift in humid foundry environments. High vibration and thermal cycling accelerate junction corrosion.
- ✓VTC thyristor module firing failure or erratic conduction — Gate driver IC failure, snubber diode short-circuit, or control signal PCB trace fracture from vibration and thermal stress during high-power melting cycles. Capacitor leakage increases gate circuit impedance.
- ✓MFC relay bank intermittent switching or stuck outputs — Contact oxidation, coil insulation breakdown, or mechanical jitter from energized relay armature bounce. Cooling water flow alarm relays fail due to moisture ingress and corrosion in damp foundry shops.
- ✓IDS IGBT module thermal runaway or short-circuit trip — Gate oxide degradation, solder joint fatigue under rapid thermal cycling (50-150°C swings), or parasitic oscillation in driver circuit causing shoot-through current. Heatsink thermal paste degradation increases junction temperature 30-40°C.
- ✓PCS capacitor bank bulging, leakage, or dielectric breakdown — Capacitor electrolyte oxidation and gas generation from sustained high-frequency ripple current in harmonic-rich foundry power systems. Thyristor switching transients and DC bus voltage spikes (>10% overvoltage) accelerate dielectric failure.
- ✓RTM wireless temperature module link dropout or noisy signal — 2.4 GHz interference from nearby WiFi routers, mobile charging stations, or microwave ovens in foundry break rooms. Antenna corrosion and connector pin oxidation degrade RF coupling. Hardwired RTM modules suffer noise from furnace coil dI/dt radiation.

Frequently Asked Questions — INDUTHERM FLS Repairs
Do you repair INDUTHERM FLS equipment anywhere in India?+
Yes. Synchronics repairs the complete INDUTHERM FLS range - FLS controllers, VTC thyristor modules, MFC sequencers, IDS frequency converters, PCS power conditioning, and RTM temperature systems. We offer PAN India pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. All repairs are carried out at our Vadodara, Gujarat facility with 24-48 hour TAT for most faults.
What is the typical repair turnaround time for INDUTHERM FLS VTC thyristor modules?+
Standard VTC module repair (thyristor replacement, snubber diode testing, gate driver IC swap) takes 24-36 hours including functional testing. Expedited service available for critical production furnaces - we can prioritize your unit within 12 hours if notified in advance. Complex cases involving custom power level tuning may extend to 48-72 hours.
Can Synchronics repair INDUTHERM FLS furnace controllers that show 'Sensor Error' or 'Communication Timeout' faults?+
Yes. These faults typically stem from thermocouple break, analog input module reference drift, or RTM wireless module interference. Synchronics diagnoses using manufacturer-grade test equipment, replaces failed sensor cards, recalibrates input ranges to ±0.1% accuracy, and performs full system integration testing before release. We also provide recommendations on sensor shielding and wiring practices to prevent recurrence in your foundry environment.
Do you stock OEM INDUTHERM FLS spare components or rebuild using compatible replacements?+
Synchronics sources genuine OEM components for critical items: thyristor modules, power semiconductors, and sensor cartridges. For standard passive components (capacitors, resistors, connectors), we use industrial-grade equivalents rated for identical or superior specifications. All rebuilt units carry a 12-month warranty on parts and labor, backed by our 30-year repair track record serving Indian foundries and metal processors.
Which Indian metal casting and heat treatment companies trust Synchronics for INDUTHERM FLS repairs?+
We repair INDUTHERM FLS furnace systems for leading foundries in Gujarat, Maharashtra, Rajasthan, and Uttar Pradesh producing automotive components, industrial castings, and precision forgings. Our clients include mid-sized and large-scale operators running 24/7 production. We maintain relationships with furnace operators across auto suppliers, appliance manufacturing, and custom metal processors - all benefiting from our rapid, local repair capability versus international manufacturer lead times of 4-8 weeks.
How do I send my INDUTHERM FLS 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 FLS 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 FLS 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 FLS 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.
