In hazardous industrial environments across Kuala Lumpur and Selangor—such as oil refineries, chemical processing plants, and pharmaceutical facilities—standard cooling tower fans pose a significant ignition risk. ATEX Certified Axial Fans are specifically engineered to operate safely in explosive atmospheres where flammable gases, mists, or vapors may be present.
EKG M&E Sdn Bhd specializes in the sourcing, installation, and maintenance of ATEX-compliant ventilation systems, ensuring your heat rejection process meets the stringent Directive 2014/34/EU safety standards.
As an HVAC and Clean Air Specialist, we prioritize "Non-Sparking" technology. ATEX fans differ from standard axial fans in three critical safety areas:
Anti-Static Blade Materials: Standard FRP (Fiber Reinforced Plastic) can build up a static charge. ATEX-certified fans use carbon-filled or specialized conductive resins to bleed off static electricity to the ground, preventing a discharge spark.
Non-Sparking Intake and Track: The "Rubbing Strip" (the area of the fan cylinder where the blade tips pass) is lined with non-ferrous materials like stainless steel or specialized plastic. This ensures that if a blade strikes the casing due to Vibration, it will not create a mechanical spark.
Flameproof Motors (Ex d / Ex e): We integrate motors housed in heavy-duty, flameproof enclosures. These are designed to contain an internal explosion and prevent it from igniting the external atmosphere.
Safety does not mean sacrificing thermal efficiency. We ensure your ATEX fan is optimized for the Malaysian climate:
Aerodynamic Pitch Calibration: We manually calibrate the Fan Blade Pitch to ensure maximum airflow (CFM) while staying within the motor's certified temperature class (e.g., T3 or T4).
Precision Balancing: In hazardous zones, vibration is a precursor to friction and heat. We perform Dynamic Balancing to reduce mechanical stress on the Gearbox and bearings.
VSD/VFD Compatibility: We integrate ATEX-rated Variable Frequency Drives located in safe zones or within explosion-proof panels. This allows for soft-starts, reducing the "Inrush Current" and heat buildup in the motor windings.
| Zone Category | Atmosphere Type | EKG M&E Requirement |
| Zone 1 | Explosive gas likely in normal operation. | Ex d (Flameproof) + Conductive Blades. |
| Zone 2 | Explosive gas unlikely / short periods. | Ex nA (Non-Sparking) Components. |
| Temperature Class | Max Surface Temp (e.g., 135°C/200°C). | T3 or T4 Rated Drive Train. |
| Material Group | Gas Group (e.g., IIB or IIC). | Spark-Resistant Construction. |
Maintaining an ATEX fan requires specialized "Ex" certified technicians. A standard Cooling Tower Service is insufficient:
Gap Analysis: We measure the "Tip Clearance" between the blade and the fan stack to ensure it stays within the safety tolerance specified by the ATEX certificate.
Earth Bonding Continuity: We test the electrical resistance from the fan hub through the Bearings to the ground. If the continuity is broken, the fan becomes a static electricity hazard.
Seal and Gasket Inspection: We verify the integrity of the IP-rated seals on the motor and terminal boxes to prevent the ingress of corrosive, humid KL air or flammable vapors.
Certified Compliance: We provide full ATEX certification paperwork and "Ex" inspection tags required for JKKP (DOSH) and insurance audits in Malaysia.
Total System Integration: We ensure the ATEX fan is synchronized with your Drift Eliminators and Spray Nozzles to prevent moisture-induced electrical tracking.
Strategic Support: Based in Kuala Lumpur, we provide turnkey ATEX retrofits, Vibration Analysis, and 24/7 emergency support for the region's oil, gas, and chemical infrastructure.
