Fire Rated Ventilation

Fire Rated Ventilation by EKG M&E Sdn Bhd

In the dense urban corridors of Kuala Lumpur and Selangor, ventilation systems are often the primary path for fire and smoke to travel between building compartments. Fire Rated Ventilation refers to mechanical systems engineered to maintain structural integrity and contain hazardous elements during an emergency. EKG M&E Sdn Bhd provides high-performance, fire-rated installations that strictly adhere to BOMBA standards and the Uniform Building By-Laws (UBBL), ensuring your ventilation network is a safety asset rather than a liability.

The Engineering of Passive and Active Protection

Standard ventilation ducts are made of thin-gauge galvanized steel that can buckle or melt when temperatures exceed 200°C. Fire-rated systems must remain functional for at least 2 hours at temperatures reaching 250°C to 400°C.

1. Compartmentation & Integrity (FRL 120/120/120)

To prevent a fire in one room from spreading through the ceiling ducting to another, we utilize systems rated for Stability, Integrity, and Insulation:

• Stability: The duct and its reinforced support system must not collapse, keeping the airway open for smoke extraction.

• Integrity: The system must be smoke-tight. We utilize BOMBA-approved intumescent sealants at every joint and wall penetration to block toxic gases.

• Insulation: The duct must prevent radiant heat from igniting materials on the "cold side" of a fire barrier, such as electrical cables or structural timber.

2. Specialized System Components

• Fire-Rated Enclosures: We apply certified high-density rockwool wraps or fire-rated boards to standard ductwork to provide a thermal shield.

• Motorized Fire & Smoke Dampers (MFSD): These are integrated into your Fire Alarm Monitoring System (FAMS). They automatically seal off ventilation zones when smoke is detected, preserving the building's fire compartments.

• High-Temperature Materials: For mission-critical paths, we utilize heavy-gauge steel and specialized coatings that resist thermal degradation.

Critical Operational & Energy Benefits

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

• TNB Energy Efficiency (The Airtight Advantage):

  Fire-rated ventilation ducts are held to higher airtightness standards (Class C or D) than regular HVAC. This superior seal integrity minimizes static pressure loss during daily use. 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 & Regulatory Compliance:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, every building service must be optimized. Our precision-sealed systems prevent the leakage of conditioned air into unconditioned ceiling voids, protecting your Building Energy Index (BEI).

• Safe Evacuation & Tenability:

  By effectively extracting smoke and maintaining compartmentation, our systems provide the "Golden Hour" needed for occupants to exit safely and for BOMBA personnel to navigate the building during rescue operations.
