Aerosol Duct Sealing Services: AC Duct Sealing Malaysia

In the 2026 commercial landscape of Kuala Lumpur and Selangor, traditional manual duct sealing is being superseded by Aerosol Duct Sealing Services. Under the Energy Efficiency and Conservation Act (EECA) 2024, air leakage is no longer just a maintenance issue—it is a regulatory liability that inflates your Building Energy Index (BEI). While manual sealing can only reach joints accessible by hand, aerosol technology seals the entire duct network from the inside out, including hidden leaks in inaccessible ceiling voids.

EKG M&E Sdn Bhd provides turnkey aerosol sealing solutions that guarantee Airtightness Class 6 (ATC 6) compliance, directly lowering your monthly TNB electricity bill.

The Aerosol Sealing Process: Precision from Within

Aerosol duct sealing utilizes a computerized, "injection-style" approach to find and eliminate leaks that are invisible to the naked eye.

1. System Isolation & Diagnostic Testing

Before sealing, the AC system is isolated. All registers and diffusers are temporarily blocked to create a pressurized environment.

• Baseline Leakage Test: 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 Verification: The software creates a "leakage profile," providing a baseline for your Registered Energy Manager (REM) to use in mandatory annual energy audits.

2. Aerosolized Sealant Injection

A specialized machine transforms a liquid, non-toxic vinyl acetate polymer into a fine aerosol mist.

• The "Search and Seal" Logic: As the mist travels through the pressurized ductwork, it is naturally pulled toward any leak sites (holes, gaps, or loose joints).

• Self-Building Seal: The microscopic sealant 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 has been reached.

Critical Operational & Compliance Benefits

As a specialized M&E contractor, EKG 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 to maintain the desired office temperature. 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 factor in your building’s energy intensity. Aerosol sealing is the most effective way to secure a 4-Star or 5-Star Energy Label by reducing the "lost energy" component of your BEI.

• Enhanced Indoor Air Quality (IAQ):

  Leaky return ducts often "aspire" (suck in) dusty, humid, and contaminated air from the ceiling plenum. Aerosol sealing creates a hermetic air path, ensuring 100% of the air reaching your staff has been filtered and pre-cooled by the AHU, satisfying DOSH ICOP IAQ 2026 standards.
