In the industrial and chemical sectors of Kuala Lumpur and Selangor, the safe transport of hazardous vapors is a non-negotiable safety requirement. Unlike standard ventilation, Hazardous Vapor Extraction Ductwork must be engineered to withstand the specific corrosive, flammable, or toxic properties of the chemicals being handled. Failure to select the correct material or sealing method can lead to structural collapse, environmental contamination, and severe regulatory penalties.
EKG M&E Sdn Bhd specializes in "Source-Capture" engineering, providing high-integrity ducting systems that comply with DOSH LEV (Local Exhaust Ventilation) standards and DOE (Department of Environment) emission regulations.
Managing hazardous vapors requires a system that is chemically inert, hermetically sealed, and structurally robust.
The choice of material is dictated by the chemical concentration and thermal profile of the vapor:
uPVC / CPVC: The industry standard for laboratories and acid exhaust lines (Hydrochloric, Sulfuric). CPVC is utilized for high-temperature chemical processes up to 90°C.
Polypropylene (PP): Exceptional for aggressive organic solvents and high-heat chemical lines, offering superior thermal stability.
FRP (Fiberglass Reinforced Plastic): The "Gold Standard" for heavy industrial, large-diameter stacks and high-pressure systems. FRP handles temperatures exceeding 100°C and is virtually immune to chemical degradation.
To prevent hazardous vapors from leaking into ceiling voids or building plenums, the system must be airtight.
Molecular & Thermal Welding: We utilize solvent welding for PVC, thermal extrusion welding for PP, and butt-and-strap lamination for FRP.
Zero-Leakage Standard: All EKG installations are pressure-tested to Airtightness Class 6 (ATC 6), ensuring no toxic bypass air escapes the extraction path.
Negative Pressure Protocol: We typically install the extraction fan at the end of the system (downstream). This keeps the entire duct run under negative pressure, ensuring that if a physical breach occurs, air is pulled into the duct rather than hazardous vapors being pushed out into the facility.
As a specialized M&E contractor, EKG ensures your extraction system supports both plant safety and the EECA 2024 energy targets:
TNB Energy Efficiency (VFD Optimization):
Hazardous extraction often requires high static pressure. By utilizing ultra-smooth internal polymer walls and Variable Frequency Drives (VFDs), we minimize air friction. This allows the fan to maintain target capture velocities at lower power frequencies, directly reducing your monthly TNB electricity bill.
Corrosion-Proof Service Life (25+ Years):
While metal ducts in vapor-rich zones suffer from pitting and "white rust," our polymer and composite systems provide a maintenance-free life cycle of over two decades.
BOMBA & Safety Compliance:
We utilize fire-retardant (Class 0 / B1) additives in our FRP and PP-s ducting to ensure that chemical safety never compromises fire safety codes.

Total 3D BIM Coordination: We model extraction paths in 3D to ensure "clash-free" installation around existing utilities, electrical trays, and structural beams.
Turnkey Validation: We provide full Testing & Commissioning (T&C), including smoke testing to prove capture effectiveness and airflow traverse reports required for your annual Local Exhaust Ventilation (LEV) certification.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional audits and installations for semiconductor plants, pharmaceutical labs, electroplating facilities, and chemical storage hubs across Malaysia.
