Fireproof HVAC ducts

Fireproof HVAC Ducts by EKG M&E Sdn Bhd

In the high-rise commercial and industrial sectors of Kuala Lumpur and Selangor, air ducts are necessary for comfort but can become dangerous conduits for flame and smoke during an emergency. Fireproof HVAC Ducts (technically referred to as Fire-Rated Ducts) are engineered to withstand extreme temperatures while maintaining their structural integrity. EKG M&E Sdn Bhd provides high-performance, fire-rated solutions that strictly adhere to BOMBA standards and the Uniform Building By-Laws (UBBL).

The Engineering of Fire Resistance (FRL 120/120/120)

Standard HVAC ducting is typically made of thin-gauge galvanized steel that will buckle or melt at temperatures as low as 200°C. Fireproof systems must meet the Fire Resistance Level (FRL) of 120 minutes across three critical criteria:

1. Stability (Mechanical Strength)

The duct and its reinforced support system must not collapse when exposed to extreme heat. This ensures that the air path remains open, which is vital for systems like smoke extraction or staircase pressurization that must operate during a fire.

2. Integrity (Containment)

The system must be smoke-tight and flame-tight. We utilize BOMBA-approved intumescent sealants at every joint and wall penetration. These materials expand significantly when exposed to heat, sealing gaps to prevent fire and toxic gases from "leaking" into non-affected building zones.

3. Insulation (Thermal Barrier)

The duct must prevent radiant heat from transferring to the "cold side." This ensures that combustible materials—such as data cables, furniture, or structural insulation—located outside the fire zone do not spontaneously ignite due to rising temperatures.

Critical Operational & Energy Benefits

As a BOMBA-Compliant M&E Specialist, EKG ensures that your safety infrastructure supports long-term operational efficiency:

• TNB Energy Efficiency (The Airtight Advantage):

  Fireproof ducts are held to much higher airtightness standards (Class C or D) than regular HVAC. This superior seal integrity minimizes static pressure loss during daily operations. By eliminating air waste, your Variable Frequency Drive (VFD) can maintain required airflows at lower frequencies (Hz), 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 leakage of conditioned air into unconditioned ceiling voids, protecting your Building Energy Index (BEI).

• Safe Evacuation & Tenability:

  By effectively containing fire and smoke within a certified conduit, our systems maintain breathable zones and visibility in escape routes, providing the "Golden Hour" needed for safe occupant egress and for BOMBA personnel to initiate rescue operations.
