In the tropical industrial landscape of Kuala Lumpur, a Gravity Vent Installation is the foundation of a "Zero-Energy" cooling strategy. These units—whether Aluminum Spun, Galvanized Relief, or Intake Hoods—rely on the Stack Effect to exhaust rising heat. However, a "hole in the roof" is not an installation; if poorly executed, it leads to structural sagging, massive monsoon leaks, and localized "Heat Pockets."
As part of a Ventilation Systems Audit, EKG provides precision-engineered installations that integrate seamlessly into your building’s mechanical and structural envelope.
A professional installation must manage the extreme hydraulic and thermal loads of the 2026 Malaysian climate:
Structural Purlin Integration: We never mount a heavy ventilator solely to the metal roof decking. We tie the Vent Curb directly into the structural purlins. This prevents "Roof Deflection" that causes water to pool and rust the surrounding sheets.
The 300mm Standard: To prevent "Splash-Back" during heavy tropical downpours, we install all vents on curbs a minimum of 300mm high. This keeps the intake/exhaust clear of surface-water rushing across the roof.
Acoustic & Thermal Lining: We line the internal "Throat" with 25mm Rigid Insulation. This prevents "Condensation Rain"—the dripping caused by the temperature difference between the hot roof and your cool, air-conditioned interior.
We treat every roof penetration as a high-risk mechanical interface:
Mechanical "Cricket" Fabrication: On the high side of every vent, we install a "Cricket" (a triangular water-diverter). This physically breaks the flow of rushing rainwater, preventing "Damming" and the subsequent rust that destroys metal roofs.
Marine-Grade Poly-Hybrid Sealants: We have moved beyond standard silicone. We use High-Build Polyurethanes that remain flexible (up to 25% movement) under KL’s 70°C roof temperatures.
Double-Flashing Geometry: We use a "Base Flashing" integrated into the roof sheets and a "Counter-Flashing" that sleeves over the vent. This creates a redundant water barrier that uses gravity—not just glue—to shed water.
Thermal Mapping for Placement: We use FLIR Thermal Cameras to identify the exact "Heat Centers" of your warehouse or factory. Placing a vent even 2 meters away from a heat-generating machine can reduce its efficiency by 30%.
A "Slick" installation is the best friend of your Variable Frequency Drives (VFDs) on other mechanical fans.
Reducing "Entrance Friction": If a vent is installed with internal obstructions or a "choked" throat, it creates turbulence that your mechanical fans must fight against.
The Logic: By ensuring a laminar air path during installation, we lower the static resistance ($P$) of the entire building.
Because of the Cube Law, reducing the "Flow Resistance" so your mechanical fans can run 10% slower reduces your daily cooling energy consumption by nearly 30%.
| Component | EKG Standard | Risk of Failure |
| Mounting Curb | Purlin-Anchored & Insulated | Structural Sagging / Roof Leaks |
| Flashing / Sealant | UV-Stable Poly-Hybrid | Seal Cracking / "Ghost Leaks" |
| Water Management | High-Side "Cricket" Installed | Water Puddling & Rapid Rust |
| Internal Throat | Smooth & Obstruction-Free | Air Turbulence / Noisy Whistling |
| Fasteners | 316 Stainless Steel | Galvanic Corrosion / Loose Vents |
Building Envelope Expertise: We don't just "cut a hole"; we preserve the structural and thermal integrity of your building.
Mechanical Restoration Path: If you have existing vents that were poorly installed, we are experts in Mechanical Fan Overhauls, offering complete "Curb & Flashing" retrofits.
VFD-Energy ROI Projection: We calculate the TNB savings achieved by "Relieving" your building’s thermal load through precision passive venting.
2026 KL Ready: We use only non-corrosive, marine-grade materials designed for the high acidity and humidity of the Klang Valley.
