In 2026, Snap-Lock Flexible Duct Collars represent a significant advancement in achieving the hermetic terminal connections required by the Energy Efficiency and Conservation Act (EECA) 2024. For commercial and industrial facilities in Kuala Lumpur and Selangor, the interface between a rigid main duct and a flexible transition is the most common site for "Pressure Bleed." Snap-lock technology replaces traditional manual crimping with a mechanical interference fit that ensures consistent seal integrity and optimizes your Building Energy Index (BEI).
EKG (Malaysia) Sdn Bhd utilizes 34 years of mechanical engineering expertise to provide instrument-verified snap-lock collar installations. We focus on achieving SMACNA Class C airtightness at every terminal point to ensure your Variable Frequency Drives (VFDs) operate at peak efficiency.
In Malaysia's high-pressure HVAC systems, standard collar connections often fail due to thermal expansion or poor manual sealing.
Mechanical Interference Fit: Snap-lock collars utilize a pre-engineered "bead and groove" system. When the collar is snapped into the rigid duct plenum, it creates a high-tension mechanical lock that does not loosen over time. This prevents the air leakage that typically causes supply fans to overwork, directly lowering your monthly TNB maximum demand.
Hermetic Gasket Integration: EKG utilizes snap-lock collars equipped with factory-fitted EPDM or silicone gaskets. Unlike manual mastic application, which can be inconsistent, the gasket provides a 360° airtight seal upon engagement, satisfying the rigorous MS 1525:2024 leakage standards.
Uniform Airflow Transition: By providing a perfectly circular and rigid mounting point, snap-lock collars ensure that the Antimicrobial Flexible Duct is attached without "ovaling." This preserves the aerodynamic profile of the air path and reduces internal turbulence.
To meet SIRIM, DOSH, and BOMBA 2026 benchmarks, EKG utilizes a rigorous "High-Integrity" handshake:
The snap-lock collar provides the anchor, but the seal to the flex duct is equally critical. We utilize a Dual-Clamping Protocol: the antimicrobial inner core is mastic-sealed to the collar's "beaded" neck and secured with a stainless steel tension band. The R-6.0 to R-8.0 insulation is then pulled over and sealed separately to prevent "sweating."
Given the high humidity in the Klang Valley, all our snap-lock collars are constructed from G90 rated galvanized steel or stainless steel. This prevents the "pitting" corrosion that can compromise the hermetic seal in damp ceiling voids, ensuring the longevity of your HVAC asset.
For VAV (Variable Air Volume) terminals, we utilize specialized snap-lock start collars that include a radius-entry (bell-mouth) design. This reduces the entry loss coefficient, allowing air to transition from the main duct into the flex branch with minimal resistance, further improving your building's energy intensity label.

Audit-Ready Reporting: Under the EECA 2024, technical evidence of air distribution efficiency is mandatory. We provide on-site Duct Leakage Testing (DLT) specifically at the collar-plenum interface to serve as proof of performance for your annual energy audit.
Thermal Integrity Verification: We utilize Infrared (IR) Scanning to ensure that the collar connection remains thermally isolated and condensation-free, protecting your ceiling assets and satisfying DOSH 2026 IAQ audits.
Operational Longevity: Snap-lock connections are designed to withstand the static pressure fluctuations of modern "Smart Buildings," preventing the mechanical fatigue that leads to "hissing" and energy loss in older facilities.
34 Years of Technical Forensics: We understand why terminal connections fail in the Malaysian climate and why engineered mechanical locks are superior to manual methods.
Turnkey Engineering: From system design to final Testing, Adjusting, and Balancing (TAB), we provide the instrument-verified data needed to prove system performance.
BIM & Digital Twin Integration: We provide full 3D as-built data for your terminal connections, allowing for seamless integration into modern facility management software.
