Smoke Extraction Ducting by EKG M&E Sdn Bhd

In the commercial and high-rise developments of Kuala Lumpur and Selangor, a Smoke Extraction Ducting system is the most critical life-safety component of your building’s M&E infrastructure. Unlike standard ventilation, these systems are engineered to perform under extreme thermal stress, physically removing toxic smoke and heat during a fire to maintain a "tenable environment" for evacuation. EKG M&E Sdn Bhd specializes in the design, installation, and BOMBA-certified commissioning of smoke spill systems that comply with UBBL (Uniform Building By-Laws).

The Logic of "Emergency Air Management"

Smoke extraction is a specialized "Once-Through" air strategy. The system remains dormant during normal operations but must activate instantly to 100% capacity the moment a fire signal is received.

1. High-Temperature Material Integrity

Smoke spill ducts must maintain structural stability at temperatures exceeding $250^{\circ}\text$ for up to 2 hours.

• Heavy-Gauge Galvanized or Black Steel: We utilize ductwork fabricated to much higher thickness specifications than standard HVAC ducts to prevent collapsing under intense suction and heat.

• Fire-Rated Coatings & Wraps: For ducts passing through "protected lobbies" or escape routes, we apply certified fire-rated insulation or intumescent coatings to prevent the heat inside the duct from igniting materials outside of it.

2. Specialized Smoke Spill Fans

The "Engine" of the extraction system is the high-temperature rated fan, typically mounted on the rooftop or in a dedicated plant room.

• Class H Insulation: We utilize motors specifically rated for emergency duty (e.g., F300 or F400 ratings), ensuring the fan continues to pull smoke even if the air stream itself is scorching hot.

• Dual-Speed / VFD Readiness: During normal hours, these fans can sometimes be used for general ventilation at low speeds via a Variable Frequency Drive (VFD). However, the system is programmed with a "Fire Override" that bypasses all energy-saving logic to run at maximum RPM during an alarm.

Critical Installation & Compliance Standards

As an HVAC and M&E Specialist, EKG ensures your smoke extraction ducting is a precision-integrated part of your building’s safety shell:

• TNB Power Reliability (Secondary Power Sync):

  A smoke spill system is useless without power. We ensure the ducting and fan systems are interlocked with your building's Emergency Generator or UPS, ensuring the extraction continues even if the main TNB grid fails.

• BOMBA & UBBL Compliance:

  Every installation we perform is designed to pass the stringent BOMBA "Smoke Test." We ensure the "Extraction Rate" (measured in air changes per hour) meets the specific requirements for your building’s volume and occupancy type.

• Acoustic & Vibration Integrity:

  Smoke fans are incredibly powerful and loud. We use high-temperature vibration isolators to ensure that during testing or emergency use, the mechanical vibration does not compromise the building's structural masonry or steel supports.
