In the industrial corridors of Kuala Lumpur and Selangor, a Safety Exhaust System (SES) is a high-integrity ventilation network designed to protect personnel and property from hazardous gases, toxic fumes, and combustible dust. Unlike standard ventilation, an SES is a fail-safe system—it must operate reliably during process upsets, gas leaks, or emergency shutdowns to prevent the accumulation of life-threatening atmospheres.
EKG M&E Sdn Bhd specializes in the engineering, installation, and JKKP (DOSH) LEV certification of safety exhaust infrastructure, adhering to NFPA 91, ACGIH, and USECHH Regulations.
As an HVAC and Clean Air Specialist, we design the system architecture based on the "Containment Strategy" required for your specific chemicals:
The primary line of defense. It captures contaminants at the point of release (e.g., a chemical mixing tank or a lab hood) before they reach the operator's breathing zone.
EKG Touch: We utilize Variable Frequency Drives (VFDs) to maintain a constant "Face Velocity," ensuring that even as filters get dirty, the suction power remains identical.
Activated only during a detected leak or spill. These systems are linked to Gas Detectors and are designed to "flush" a room with fresh air in under 60 seconds.
EKG Touch: We program the VFD to perform a "Fast Ramp" to maximum RPM the moment a sensor hits 10% of the Lower Flammability Limit (LFL).
A safety exhaust system is only as strong as its weakest link. We specify components that can survive harsh or explosive environments:
Spark-Resistant Fans (AMCA Type A/B): Constructed from non-ferrous materials (Aluminum or FRP) to prevent mechanical sparks if the impeller strikes the housing.
Flameproof (Ex d) Motors: Heavy-duty enclosures that contain internal electrical faults, preventing them from igniting the hazardous exhaust stream.
High-Plume Dilution Stacks: Specially engineered exhaust nozzles that eject fumes high into the atmosphere at high velocity, preventing "re-entrainment" (fumes being sucked back into the building's fresh air intakes).
For critical processes, "Single Point of Failure" is unacceptable. We implement redundancy:
| Feature | Standard Exhaust | EKG Safety Exhaust |
| Fan Config | Single Fan. | Duty/Standby (N+1) with Auto-Changeover. |
| Power Source | Main Grid only. | UPS or Emergency Generator Interlock. |
| Monitoring | Visual only. | Airflow Proving Switches & VFD Fault Alarms. |
| Interlock | Manual Switch. | Automated shutdown of gas valves on fan failure. |
In Malaysia, Safety Exhaust Systems are classified as Local Exhaust Ventilation (LEV) and require mandatory annual testing:
Annual LEV Audit: We provide JKKP-registered Competent Persons to measure capture velocities, static pressures, and fan performance.
Vibration Analysis: We perform FFT spectrum analysis on the main exhaust fans to detect bearing wear early. A seized fan in a safety system can lead to an immediate factory-wide shutdown.
Duct Integrity Testing: We use smoke testing and pressure decay tests to ensure zero leakage of hazardous gases into occupied "Safe Zones."
Turnkey MEP Integration: We don't just "install a fan"—we design the gas detection logic, the VFD control panels, and the certified ductwork as a single, validated safety loop.
Certified "Ex" Expertise: Our team is trained in hazardous area equipment handling, ensuring your ATEX/IECEx certifications remain valid after installation.
Strategic Support: Based in Kuala Lumpur, we offer 24/7 emergency response for critical safety exhaust systems in the pharmaceutical, chemical, and semiconductor sectors.
