GULMAY Equipment We Repair — By Category
GULMAY Product Lines We Repair
Our engineers are trained on the full GULMAY product range. Below are the major product families we service.
Gulmay Medical X-ray Generators
Industrial and medical-grade X-ray generator units delivering stable high-voltage output for radiography and NDT applications. Common faults include filament bias instability, exposure control circuit degradation, and tube protection relay failures affecting image quality.
Gulmay Compact Tube Heads and Assemblies
Enclosed X-ray tube assemblies used in portable NDT, baggage screening, and industrial inspection systems. Repairs address tube socket degradation, HT cable insulation breakdown, and cooling fan motor failures common in high-duty industrial environments.
Gulmay High-Frequency Switching Power Supplies
Switching mode power supply modules regulating kilovoltage output and tube current in industrial X-ray systems. Typical faults include capacitor dry-out in high-temperature factory conditions, MOSFET gate driver failures, and feedback control loop instability.
Gulmay Control and Timing Electronics
Microprocessor-based boards and relay circuits managing exposure timing, tube current regulation, and safety interlocks in X-ray systems. Failures typically stem from relay contact erosion, capacitor aging, and firmware corruption in legacy models operating in harsh plant environments.
Gulmay Filament and Bias Supply Circuits
Precision analog circuits supplying stable AC and DC bias voltages to cathode filament systems. Common degradation includes transformer winding insulation failure, potentiometer contact wear causing output drift, and thermistor sensor failures affecting filament current regulation.
Gulmay High-Tension Cable Assemblies and Connectors
Custom-molded high-voltage cabling and hermetic connectors linking generator to tube heads in industrial systems. Premature failures occur due to moisture ingress, corona discharge in monsoon climates, and mechanical stress in portable NDT equipment during site transport.

Common GULMAY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GULMAY equipment arriving at our workshop.
- ✓Filament bias voltage drift and tube current instability — Gulmay filament supply circuits use precision potentiometers and reference zeners that degrade in high-temperature Indian factory environments. Electrolytic capacitors in the bias network dry out over time, causing output voltage creep and poor tube current regulation.
- ✓High-voltage secondary rectifier diode failures and arcing — Gulmay high-tension circuits employ high-voltage silicon diodes subject to transient surge stress during tube arc-over events or grid supply fluctuations common in Indian industrial zones. Diode junctions become thermally fatigued and fail prematurely.
- ✓Exposure timer circuit malfunction and exposure control errors — Gulmay legacy exposure timer boards use electromechanical relays and analog timing capacitors prone to contact degradation, capacitor leakage, and wiper arm oxidation. Humidity in coastal Indian facilities and monsoon seasons accelerate relay coil corrosion and timing drift.
- ✓Switching power supply MOSFET and gate driver failures — Gulmay high-frequency switching supplies use power MOSFETs and gate driver ICs exposed to thermal cycling in uncontrolled factory environments. Gate oxide degradation, solder joint fatigue on switching transistor legs, and driver IC junction breakdown cause intermittent shutdown and power loss.
- ✓High-voltage connector arcing and insulation tracking on tube assemblies — Gulmay tube head connectors experience corona discharge and moisture-induced tracking on epoxy moldings in humid Indian climates. Tracking carbonizes insulation pathways, creating conductive leakage paths that trigger system shutdown and tube damage risk.
- ✓Tube cooling fan motor failure and thermal runaway shutdown — Gulmay compact tube assemblies employ small DC fan motors for heat dissipation in high-duty industrial NDT cycles. Motor bearings wear rapidly in dust-laden Indian plant environments, windings short from moisture ingress, and thermal switches become sluggish, causing nuisance shutdowns.

Frequently Asked Questions — GULMAY Repairs
Do you repair Gulmay equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full Gulmay product range - X-ray generators, tube assemblies, high-voltage supplies, and control modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all major cities. Same-day turnaround coordination from our Vadodara, Gujarat facility. Call us for emergency NDT equipment repairs to minimize production downtime.
What is your turnaround time for Gulmay X-ray generator repairs?+
Most Gulmay generator repairs are completed in 3-5 business days, depending on fault complexity and parts availability. Filament supply failures, HT diode replacements, and timer circuit refurbishment are among our fastest turnarounds. High-voltage section rebuilds or custom tube head repairs may require 7-10 days. We provide daily status updates and expedited shipping across India at no extra cost for industrial clients.
Can you repair Gulmay tube heads with damaged X-ray tubes or just the electronics?+
Synchronics repairs the full Gulmay tube head assembly - electronics, connectors, cooling systems, and structural damage. If the X-ray tube itself is damaged (cracked anode, filament burnout), we source OEM Gulmay replacement tubes and rebuild the complete head. We coordinate with Gulmay's UK service network for critical tube specifications and ensure full radiological safety compliance before return.
Do you repair legacy Gulmay models and older generators?+
Absolutely. Our engineers have repaired Gulmay equipment from the 1990s to current models. Older discrete component designs and vintage electromechanical circuits are well within our expertise. We source legacy components through our global supplier network, restore solder joints, replace dated capacitors and relays, and modernize control logic where beneficial. Your legacy Gulmay system will perform like new.
What certifications and safety testing apply to Gulmay X-ray generator repairs?+
All Gulmay repairs follow IEC 61010, IEC 60601 (medical), and Indian radiological safety standards. We perform high-voltage insulation testing at 1.5x rated kilovoltage, ground continuity checks, thermal stability runs, and functional exposure tests on all rebuilt generators. Full test reports and safety certification are provided. Your repaired Gulmay equipment is approved for immediate return to production or NDT operations.
How do I send my GULMAY 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 GULMAY 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 GULMAY 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 GULMAY 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.
