In the 2026 commercial landscape of Kuala Lumpur and Selangor, Aerosol Duct Sealing has emerged as the definitive solution for achieving "Zero-Loss" air distribution. While manual sealing with mastic or tape can only address visible joints, aerosol technology (such as the industry-leading Aeroseal process) seals the entire duct network from the inside out.
Under the Energy Efficiency and Conservation Act (EECA) 2024, air leakage is now a regulatory liability. Aerosol sealing is the most efficient way to lower your Building Energy Index (BEI) and ensure your facility meets the mandatory Airtightness Class 6 (ATC 6) standards.
Aerosol sealing utilizes a computerized, "injection-style" approach to find and eliminate leaks that are invisible or inaccessible to the human eye.
Before sealing, the system is isolated, and all registers/diffusers are temporarily blocked.
The Baseline: We perform a calibrated pressure test to determine exactly how many liters per second ($L/s$) of "paid-for" cooling air are escaping into your ceiling plenum.
Digital Audit Trail: The software creates a detailed "leakage profile," providing the documented baseline required for official ST (Energy Commission) submissions.
A non-toxic, vinyl acetate polymer is aerosolized into a fine mist and injected into the pressurized ductwork.
The "Search and Seal" Logic: As the mist travels through the ducts, it is naturally pulled toward any leak sites (holes, gaps, or loose joints).
Self-Building Seal: Microscopic particles collide at the edge of the leak, bonding together to bridge gaps up to 15mm. The process continues until the computer detects that the target airtightness (ATC 6) has been reached.
As your M&E partner, EKG M&E Sdn Bhd ensures your aerosol sealing service delivers measurable ROI:
TNB Energy Savings (Up to 30% Reduction): Leaky ducts force your chillers and fans to work harder. By eliminating leaks, your Variable Frequency Drives (VFDs) can run at significantly lower frequencies, slashing your monthly "Maximum Demand" and consumption charges.
EECA 2024 Star Rating Optimization: Airtightness is a primary driver for securing a 4-Star or 5-Star Energy Label. Aerosol sealing is the fastest route to reducing the "lost energy" component of your BEI.
Enhanced IAQ (DOSH 2026): Leaky return ducts can "aspire" (suck in) dusty, humid, and contaminated air from ceiling voids. Aerosol sealing creates a hermetic air path, ensuring 100% of the air reaching your staff is filtered and pre-cooled, satisfying the DOSH ICOP IAQ 2026 standards.
| Feature | Manual Duct Sealing (Mastic/Tape) | Aerosol Sealing Services |

| Leak Reduction | 40% – 50% | 70% – 95% (Verified) |
| Downtime | High (Requires ceiling removal) | Low (No demolition required) |
| Verification | Visual only | Computerized Real-Time Data |
| EECA 2024 Status | Basic Compliance | Audit-Ready / High Star Label |
Total 3D BIM Coordination: For new projects, we model the duct network in 3D to identify "high-risk" leakage zones, ensuring the aerosol treatment is targeted for maximum effectiveness.
Turnkey Validation: Every project concludes with a Certificate of Airtightness. This includes a "Before and After" graph of your leakage rates, essential for your Registered Energy Manager (REM) and official ST audits.
Regional Support: Based in Kuala Lumpur, we provide professional aerosol sealing for Grade-A offices, hospitals, and high-occupancy retail hubs across the Klang Valley.
