Fire Rated Smoke Extract System (SES) by EKG M&E Sdn Bhd

In the urban centers of Kuala Lumpur and Selangor, managing smoke during a fire is the single most important factor for occupant survival. A Smoke Extract System (SES), also known as a Smoke Spill system, is a specialized mechanical network designed to remove toxic gases and heat from a building. EKG M&E Sdn Bhd provides high-performance, fire-rated SES installations that comply with BOMBA standards and the Uniform Building By-Laws (UBBL) to ensure clear evacuation paths.

The Engineering of Smoke Control

Unlike standard air conditioning, an SES must operate under extreme thermal stress. These systems are designed to keep smoke at a manageable level (the "smoke layer") above the heads of escaping occupants.

1. 2-Hour Fire Resistance (FRL 120/120/120)

To be effective, the extraction ductwork must remain structurally sound while transporting air that can reach temperatures between 250°C and 400°C.

• Integrity: The duct must remain smoke-tight so that toxic fumes are not leaked into non-fire zones (like stairwells) as they are being transported to the discharge point.

• Stability: The support and hanger systems are reinforced to ensure the duct does not collapse even when the metal undergoes significant thermal expansion.

2. Specialized System Components

• High-Temperature Axial Fans: We install fans certified to run at 250°C for at least 2 hours. These are linked to the fire panel and activate immediately upon a smoke signal.

• Motorized Smoke Dampers: These dampers stay open during extraction but can close to prevent the spread of fire once the extraction phase is complete or if fire enters the duct.

• Fire-Rated Enclosures: We utilize pre-fabricated fire-rated boards or high-density rockwool wraps to ensure the duct maintains its temperature rating throughout its entire length.

Critical Operational & Safety Benefits

As a BOMBA-Compliant M&E Specialist, EKG ensures your SES supports building efficiency and life safety:

• TNB Energy Efficiency (Dual-Purpose Optimization):

  Many SES networks also handle daily general ventilation (such as removing CO from basements). By ensuring the system is Class C Airtight, we eliminate air leakage. This allows your Variable Frequency Drive (VFD) to run fan motors at lower speeds during normal hours, directly resulting in a lower monthly TNB electricity bill.

• EECA 2024 & Building Compliance:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, every building service must be energy-optimized. Our precision-sealed fire ducts prevent the waste of conditioned air, protecting your Building Energy Index (BEI).

• The "Golden Hour" for Evacuation:

  By effectively buoyant-lifting and extracting smoke, our systems maintain a clear "breathable zone" at the floor level. This provides the critical window of time needed for occupants to exit safely and for BOMBA personnel to enter for rescue operations.
