In the industrial and laboratory landscapes of Kuala Lumpur and Selangor, chemical storage areas present a unique set of HVAC challenges. Unlike standard warehouses, these spaces often contain volatile organic compounds (VOCs), corrosive acids, or toxic gases. Without a dedicated Air Extraction and Scrubbing system, these vapors can reach hazardous concentrations (Lower Flammability Limits), corrode building structures, and pose severe health risks to personnel.
EKG M&E Sdn Bhd specializes in the design and installation of chemical-resistant ventilation systems that comply with JKKP (DOSH) USECHH Regulations and NFPA 30 (Flammable and Combustible Liquids Code).
Standard galvanized steel ducting will disintegrate in months when exposed to acid or solvent vapors. As an HVAC and Clean Air Specialist, we utilize specialized materials and designs:
Material Selection (PP / PVC / FRP): We install ducting made from Polypropylene (PP), PVC, or Fiber Reinforced Plastic (FRP). These materials are chemically inert, ensuring the extraction system remains structurally sound for decades.
Point-of-Source Capture: For high-risk areas like decanting stations, we integrate Fume Hoods or Snorkel Extractors to pull vapors away before they disperse into the general room air.
Negative Pressure Management: We design the system to maintain a constant "Negative Pressure" relative to the rest of the building. This ensures that if a door is opened, air flows into the chemical room, preventing toxic fumes from leaking into office or production areas.
ATEX / Explosion-Proof Fans: If flammable solvents are stored, we use ATEX-certified centrifugal fans. These feature non-sparking impellers and "Ex d" rated motors to prevent the extraction system from becoming an ignition source.
Wet Scrubbers & Carbon Adsorption: We don't just "vent" chemicals into the KL atmosphere. We integrate Wet Scrubbers (for acids) or Activated Carbon Towers (for VOCs) to neutralize the air before discharge, ensuring compliance with DOE (Department of Environment) Clean Air Regulations.
VFD Modulation: We install Variable Frequency Drives (VFDs) on the main extraction fans. This allows the system to run at a "trickle" rate during low-load periods and ramp up to emergency speeds if a leak is detected.
A chemical extraction system must be intelligent enough to respond to emergencies:
| Component | Function | EKG M&E Implementation |
| Gas Detectors | Identifies specific leaks. | Linked to VFD for emergency ramp-up. |
| Airflow Switches | Confirms the fan is spinning. | Triggers alarm if the belt snaps/motor trips. |
| Emergency Power | Ensures constant suction. | Connected to UPS or Essential Genset. |
| Scrubber PH Control | Monitors neutralizing liquid. | Automated chemical dosing for the scrubber. |
JKKP (DOSH) Compliance: We provide the "Local Exhaust Ventilation" (LEV) certification and testing required by Malaysian law for chemical handling facilities.
Custom Engineering: Based in Kuala Lumpur, we design tailored systems for everything from small flammable cabinets to massive chemical warehouses.
Predictive Maintenance: We offer Vibration Analysis for high-speed extraction fans and ultrasonic thickness testing for chemical-resistant ducting to identify wear early.
