In the specialized environments of Kuala Lumpur and Selangor, while Carbon Monoxide (CO) is the primary concern for general carparks, Basement CO2 Extraction is a critical requirement for high-occupancy basements, enclosed growth chambers, or specialized storage facilities (such as those for medical gases or fire suppression systems). Since CO2 is heavier than air, it naturally pools at the lowest levels of a structure, creating "asphyxiation zones" if not mechanically managed.
EKG M&E Sdn Bhd provides high-performance extraction systems designed to monitor, detect, and flush Carbon Dioxide levels to ensure compliance with OSHA, BOMBA, and MS 1780 standards.
Unlike lighter pollutants, CO2 management requires a specific ductwork and sensor configuration to be effective.
Because CO2 is denser than standard air, it settles near the floor.
Extraction Placement: We position extraction grilles at low levels (typically within 300mm of the floor) to capture the heaviest gas concentrations.
Air Displacement: Fresh air is supplied at high levels to create a downward "displacement flow," effectively pushing the CO2 toward the floor-level extraction points.
TWA (Time-Weighted Average) Monitoring: Our systems are linked to CO2 sensors calibrated to trigger at 5,000 ppm (the OSHA Permissible Exposure Limit).
Automated Flush Cycles: When levels rise, the system automatically ramps up the Variable Frequency Drive (VFD) to full capacity, performing a high-volume air change to restore oxygen levels.
As a specialized M&E contractor, EKG ensures your CO2 infrastructure supports building safety and efficiency:
TNB Energy Efficiency (Demand-Controlled Ventilation): Constantly extracting air from a basement is an energy drain. We utilize Demand-Controlled Ventilation (DCV). The fans only operate at high speed when the sensors detect a CO2 buildup. This precision reduces your monthly TNB electricity bill while ensuring 24/7 safety.
EECA 2024 & Safety Compliance: Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be energy-optimized. Our systems utilize high-efficiency motors and Class C Airtight ducting to ensure every watt of energy is used for effective gas removal.
FRL 120/120/120 Fire-Rated Integration: In many basements, the CO2 extraction ductwork doubles as the Smoke Spill system. We utilize 1.2mm heavy-gauge G.I. encased in BOMBA-approved fire-rated boards. This ensures the system stays functional for 2 hours during a fire event.
| Feature | Carbon Monoxide (CO) Extraction | EKG Carbon Dioxide (CO2) Extraction |
| Gas Density | Similar to Air | Heavier than Air (Pools at Floor) |
| Grille Placement | High and Low Levels | Primarily Low Level (Bottom 300mm) |
| Primary Source | Vehicle Exhaust | Occupant Respiration / Gas Storage |
| Detection Limit | 25 - 50 ppm | 5,000 ppm (Safety Limit) |
| Duct Rating | 2-Hour Fire Rated | 2-Hour Fire Rated (Dual Purpose) |
Total 3D BIM Coordination: Low-level extraction requires specific duct routing through basement walls and around parking stalls. We utilize 3D modeling to ensure zero "clashes" with plumbing or electrical services while preserving maximum vehicle space.
Turnkey BOMBA Submission: We perform the mandatory Gas Detection Calibration and Airflow Traverse Tests required for your annual Fire Certificate (FC) renewal.
Specialized Application Support: We provide technical proposals for data centers (CO2 suppression), indoor farming basements, and high-density retail storage across Malaysia.
