AJAX MAGNETHERMIC Product Lines We Repair
Our engineers are trained on the full AJAX MAGNETHERMIC product range. Below are the major product families we service.
Ajax Magnetic Inductor (AMI) Series
Core induction melting and heating systems for ferrous and non-ferrous metal processing. Common issues include capacitor degradation, cooling water contamination, and power factor correction circuit failures affecting frequency stability and heating efficiency.
Static Power Supply Units (SPU)
Solid-state converter systems that transform single or three-phase AC to variable frequency output for induction coils. Frequent faults include thyristor failures, gate drive circuit malfunctions, and DC bus capacitor aging causing voltage ripple and coil resonance issues.
Water Cooled Capacitor Banks (WCCB)
Resonant and matching capacitor assemblies essential for induction circuit tuning and power factor correction. Dielectric breakdown, water blockage in cooling jackets, and electrolyte leakage are primary failure modes leading to frequency drift and system instability.
Control and Instrumentation Modules (CIM)
Intelligent control systems managing frequency sweep, power ramp, temperature monitoring, and system protection. PCB trace corrosion, electrolytic capacitor failure, and relay contact oxidation cause loss of process parameter control and spurious fault alarms.
Coupling and Matching Coil Assemblies
Custom wound transformer and coil units transferring RF energy to work coils with minimal loss. Mechanical vibration fatigue, insulation breakdown from thermal cycling, and turn-to-turn short circuits reduce coupling efficiency and generate excessive heat.
Cooling System Components
Integrated water circulation, filtration, and thermal management modules maintaining optimal AJAX MAGNETHERMIC equipment operating temperatures. Pump cavitation, heat exchanger fouling, thermostat valve stiction, and flow sensor failures cause temperature runaway and component thermal damage.

Common AJAX MAGNETHERMIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AJAX MAGNETHERMIC equipment arriving at our workshop.
- ✓Capacitor bank dielectric breakdown and leakage — AJAX MAGNETHERMIC water-cooled capacitor banks operate at high voltage and frequency stress. Thermal cycling, moisture ingress through corroded water jacket seals, and prolonged operation above rated KVAR cause dielectric degradation and catastrophic failure, shutting down the entire induction heating circuit.
- ✓Thyristor and gate drive circuit failure — AJAX MAGNETHERMIC solid-state power supplies depend on thyristor switching for frequency control. Gate drive transformer saturation, isolated power supply failure, and capacitive coupling circuit breakdown prevent gate pulse delivery, causing thyristor latching or no-fire conditions and complete loss of heating power.
- ✓Coupling coil turn-to-turn shorts and insulation failure — AJAX MAGNETHERMIC coupling and matching coils endure extreme RF stress, thermal cycling, and mechanical vibration in foundry environments. Enamel insulation cracks, core saturation creates localized hotspots, and vibration-induced turn slippage generate short-circuit paths reducing coupling efficiency and overheating the coil assembly.
- ✓Frequency drift and loss of resonance tuning — AJAX MAGNETHERMIC induction systems rely on precise LC resonance for maximum power transfer to work coils. Capacitor value drift due to aging or temperature change, inductor core saturation from contamination, and control circuit calibration drift cause operating frequency to deviate from design tuning, reducing heating efficiency and increasing power factor.
- ✓Water cooling system blockage and thermal runaway — AJAX MAGNETHERMIC equipment generates substantial heat in capacitor banks, coils, and transformers demanding continuous cooling water circulation. Mineral deposits, corrosion particulates, and algae growth block water jackets reducing cooling capacity. Thermostat valve stiction and flow sensor failure mask rising temperatures until catastrophic component failure occurs, especially in Indian industrial water quality.
- ✓Control PCB electrolytic capacitor failure and spurious faults — AJAX MAGNETHERMIC control circuit boards use aluminum electrolytic capacitors for power supply filtering and analog signal coupling. Thermal stress, voltage surges from induction transients, and moisture absorption cause electrolyte drying and capacitor leakage. Failed filter capacitors degrade DC rail stability causing erratic frequency control, false temperature readings, and phantom fault alarm generation.

Frequently Asked Questions — AJAX MAGNETHERMIC Repairs
Do you repair AJAX MAGNETHERMIC equipment anywhere in India?+
Yes. Synchronics repairs the complete AJAX MAGNETHERMIC induction heating product range including power supply units, capacitor banks, coupling coils, control modules, and cooling systems. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all major industrial cities. Equipment is serviced at our certified facility in Vadodara, Gujarat with express turnaround for critical metal processing operations.
What is typical repair cost and turnaround time for AJAX MAGNETHERMIC capacitor bank failures?+
AJAX MAGNETHERMIC water-cooled capacitor bank repair typically costs 15,000-45,000 INR depending on bank size and element count, with 5-7 day turnaround including water jacket service and high-voltage testing. Synchronics maintains common capacitor elements in stock for rapid replacement. Critical installations can receive expedited service within 48 hours. Preventive capacitor bank servicing costs 8,000-12,000 INR annually and extends operational life 3-5 years in Indian foundry environments.
How do I know if my AJAX MAGNETHERMIC coupling coil needs rewinding versus replacement?+
Synchronics performs non-destructive insulation resistance testing (megohm meter at 500V) and impedance sweeping (network analyzer) to detect turn shorts and insulation damage. Coils with insulation resistance below 50 megohms at any winding or impedance mismatches exceeding 10% require reinsulation. Mechanical vibration damage, core delamination, or water ingress typically necessitates replacement. For custom coils, replacement lead time is 10-14 days; standard AJAX MAGNETHERMIC coils we source from authorized suppliers with 3-5 day delivery in India.
What preventive maintenance should I perform on AJAX MAGNETHERMIC induction heating systems?+
Synchronics recommends quarterly water system flushing and filter replacement (critical in Indian hard water regions), semi-annual cooling system thermostat and flow sensor calibration, annual capacitor bank megohm testing and thermal imaging of coupling coils, and biennial full system impedance characterization. Preventive maintenance contracts through Synchronics cost 30,000-60,000 INR annually and typically prevent 80% of emergency failures in continuous-duty foundry environments, protecting your production schedule.
Can Synchronics repair frequency stability issues in older AJAX MAGNETHERMIC systems?+
Yes. Synchronics diagnoses frequency drift through LC resonant circuit analysis using impedance measurement. We recalibrate frequency sweep control circuits, replace aged capacitor elements drifting from original KVAR ratings, and verify inductor core saturation is within design margins. For legacy systems, we can upgrade frequency monitoring with modern digital instrumentation while maintaining compatibility with existing AJAX MAGNETHERMIC power supply architecture. Contact us for system assessment — many 15-20 year old installations in Indian foundries can be restored to design performance for 40,000-80,000 INR versus 200,000+ INR replacement.
How do I send my AJAX MAGNETHERMIC unit for repair?+
