ATEX Product Lines We Repair
Our engineers are trained on the full ATEX product range. Below are the major product families we service.
ATEX Explosion-Proof Motors (IEC Standard)
Three-phase squirrel cage motors rated Group II Category 2G/3G for gas/vapor atmospheres and Group II Category 2D/3D for dust zones. Common failures include bearing degradation in sealed enclosures, winding insulation breakdown due to thermal stress in Group IIC hydrogen-rich environments, and corrosion of aluminum castings.
ATEX Variable Frequency Drives (VFDs) and Motor Starters
Frequency inverters and soft starters with ATEX certification for controlling motor speed in explosive atmospheres while limiting surface temperature and preventing ignition sources. Typical faults include IGBT module failures, capacitor dry-out in sealed thermal enclosures, and firmware corruption in safety-critical control logic for temperature monitoring.
ATEX Control Enclosures and Junction Boxes
Flameproof (Exd) and increased-safety (Exe) enclosures containing control terminals, contactors, and signaling devices rated for gas Group IIC, IIB, or IIA. Repair involves sealed connector erosion, internal corrosion from moisture ingress around cable glands, and paint damage compromising flameproof integrity.
ATEX Lighting Systems (Intrinsic Safety & Flameproof)
LED and halogen fixtures designed for hazardous zones with either intrinsic safety (Exi) or flameproof (Exd) construction. Common issues include LED driver failure, thermal cycling damage to sealed optics, and degradation of flameproof glass elements due to chemical vapor exposure.
ATEX Proximity and Limit Sensors
Inductive, capacitive, and photoelectric sensors rated for gas and dust atmospheres with intrinsic safety or flameproof certification. Failures stem from sensing face fouling in dusty zones, connector corrosion in oil/moisture-rich environments, and electronics module breakdown in high-temperature areas.
ATEX Pushbutton Stations and Control Switches
Heavy-duty command devices with increased-safety or flameproof construction for explosive atmosphere process control. Contact erosion from high inrush currents, seal degradation allowing moisture/dust ingress, and mechanical jamming of stainless steel actuators are prevalent repair calls.

Common ATEX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ATEX equipment arriving at our workshop.
- ✓ATEX motor bearing seizure in sealed Group IIC — Flameproof sealed enclosures prevent heat dissipation from continuous high ambient temperature operation in hydrogen-rich atmospheres. Grease oxidation and bearing preload creep in restricted ventilation conditions accelerates wear, eventually seizing the rotor.
- ✓ATEX VFD IGBT module thermal runaway and short — In sealed thermal enclosures, inadequate heat transfer from the inverter power stage combined with humidity-induced tracking between IGBT gate and emitter leads to gate oxide failure and conducting-state short circuits. High dv/dt transients during motor startup accelerate the degradation.
- ✓ATEX enclosure flameproof gasket degradation and internal corrosion — Over-tightening or under-tightening of flange bolts during maintenance compresses gasket material unevenly, creating micro-gaps that allow moisture and corrosive vapors (H2S, sulfur dioxide) to ingress into sealed spaces. Internal condensation accelerates corrosion of copper terminals and aluminum bus bars.
- ✓ATEX proximity sensor intrinsic safety barrier failure — The zener diode or series resistor network in the intrinsic safety (Exi) barrier module experiences thermal aging, moisture ingress, or surge transient damage. Loss of current limiting allows unsafe energy levels to reach the sensing electronics in explosive atmospheres, violating certification.
- ✓ATEX LED light fixture driver failure and no output — The high-frequency DC-DC converter or buck regulator powering LEDs in sealed flameproof housings fails due to component wear-out, capacitor drying, or transient surge damage during switchgear operation. LED forward voltage shift can also cause feedback loop instability.
- ✓ATEX pushbutton station contact erosion and unreliable switching — High inrush currents during motor soft-starter or VFD command switching create electrical arcing across contact surfaces in the enclosed pushbutton module. Arc energy erodes contact material (silver or gold plating), increasing contact resistance and eventually causing intermittent or complete loss of command signal.

Frequently Asked Questions — ATEX Repairs
Do you repair ATEX equipment anywhere in India?+
Yes. Synchronics repairs the complete ATEX product portfolio across all groups, categories, and temperature classes — explosion-proof motors, VFDs, control enclosures, sensors, lighting, and pushbutton stations. We offer PAN India logistics with door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all industrial cities. Equipment is serviced in our Vadodara, Gujarat facility and returned with full ATEX compliance certification.
What does ATEX certification mean and why is it critical for my plant?+
ATEX (Directive 2014/34/EU) mandates that all electrical equipment used in potentially explosive atmospheres — gas, vapor, or dust zones — must be certified for the specific hazardous area classification (Group II for industrial gas/vapor, Group III for dust; Categories 2G/2D for normal operation, 3G/3D for rare fault conditions). Failure to use ATEX-certified equipment or operating non-compliant repaired equipment exposes your plant to regulatory fines, insurance liability, and most critically, worker injury or death from explosions. Indian regulatory bodies and Directorate General of Factory Advice Service and Labour Institutes (DGFASLI) enforce ATEX compliance in chemical, pharma, grain, and mining sectors.
Can you repair my ATEX motor or drive and restore it to original certification?+
Absolutely. Synchronics possesses the technical expertise, test equipment (thermal imaging, high-voltage testers, compliance calibrators), and spare parts inventory to repair ATEX motors, VFDs, and control systems to their original design and certification standard. We follow OEM repair procedures, replace components with ATEX-rated equivalents, re-seal flameproof enclosures per engineering drawings, perform temperature-rise and functional validation tests, and issue a repair certificate confirming restoration to certified status. Non-certified repair voids equipment warranty and creates legal liability — Synchronics ensures your equipment is safe and compliant.
My ATEX motor overheated and is now making noise — what should I do?+
Stop operation immediately to prevent bearing seizure, mechanical failure, or potential ignition source in the explosive atmosphere. Transport the motor to Synchronics without attempting field repairs. We will conduct thermal imaging, bearing runout inspection, insulation resistance testing, and vibration analysis to identify root causes — typically bearing wear, winding fault, or thermal cycling damage in sealed enclosures. Depending on severity, we rewind the stator, replace bearings with ATEX-rated spares, and validate motor temperature rise under load before return.
How long does an ATEX equipment repair typically take?+
Standard motor or drive repair takes 5-10 working days depending on parts availability and internal damage severity. Complex cases involving rewinding, flameproof enclosure reconditioning, or firmware restoration may extend to 2-3 weeks. Synchronics maintains a large stock of ATEX-certified spare parts (motors, VFD modules, barriers, gaskets, sensors) to minimize lead time. We provide daily repair status updates and expedited service for critical production equipment — many customers maintain spare ATEX units to rotate during repair cycles.
How do I send my ATEX 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 ATEX 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 ATEX 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 ATEX 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.
