In the high-density F&B hubs of Kuala Lumpur and Selangor, grease leakage from overhead ducting is a critical failure that impacts hygiene, damages interior finishes, and presents a severe fire hazard. EKG M&E Sdn Bhd provides specialized Anti-Drip Commercial Grease Ductwork, engineered to ensure that condensed oils and fats remain strictly contained within the air conveyance system until they are safely drained. We help operators eliminate "grease rain" in their kitchens and dining areas while maintaining full compliance with BOMBA (Fire Safety) and MHLG regulations.
An anti-drip system is defined by its ability to manage phase changes—when hot grease vapors cool down and turn back into liquid. We achieve this through a combination of material science and precision fabrication.
1. Liquid-Tight "Zero-Leak" Construction
Standard mechanical seams (Pittsburgh or Snap-locks) are designed for air, not liquids. Over time, grease seeps through these folds.
Continuous Longitudinal Welds: We utilize fully penetrated TIG or MIG welds along the entire length of the duct. This creates a monolithic steel tube that is physically incapable of leaking, even if it becomes partially filled with liquid grease.
Internal "Lapped" Girth Joints: When joining sections, we utilize a shingle-lap design where the upstream section fits inside the downstream section. This ensures that gravity pulls the grease toward the next joint rather than pushing it against the seal.
2. Engineered Slope and Drainage Logic
Stagnant grease is the primary cause of leakage. If grease doesn't move, it finds a way out.
Mandatory Pitch (Slope): We engineer all horizontal runs with a minimum slope of 1:50 (approx. 20mm per meter) toward the hood or a dedicated collection point.
Strategic Low-Point Drains: For long runs, we install liquid-tight Grease Reservoirs with removable plugs. This allows maintenance teams to drain accumulated oil safely without opening the main ductwork.
3. Thermal Integrity (Prevention of Premature Condensation)
If the exhaust air stays hot, the grease stays in a vapor state and reaches the filters or fans more efficiently.
External Thermal Lagging: We apply high-density fire-rated rockwool insulation. By keeping the internal duct temperature above the "grease solidification point," we reduce the volume of liquid buildup within the system.
As an M&E specialist, EKG ensures the anti-drip circuit is built for long-term operational safety:
Grease-Rated Access Doors:
Traditional access panels are common leak points. We utilize Bolted, Gasketed Access Doors specifically rated for grease ducting. These features include high-temperature ceramic or silicone gaskets that remain liquid-tight under constant thermal expansion and contraction.
VFD-Driven "Scavenging" Velocity:
We utilize Variable Frequency Drives (VFDs) to maintain a constant "Scavenging Velocity" of 1,800 to 2,200 FPM. This high-speed airflow uses kinetic energy to "sweep" the duct walls, pushing liquid grease toward the collection points and preventing it from settling.
Ecology Unit (ESP) Coordination:
To further reduce the liquid load, we integrate our ducting with Electrostatic Precipitators (ESP). By removing the bulk of the grease particles early in the run, we significantly decrease the rate of internal condensation and the risk of drips.

Total Leakage Risk Audit: We perform site audits to identify "sagging" ducts or failing joints in existing kitchens, providing professional retrofits that solve the root cause of grease drips.
BOMBA & MHLG Compliance: Our designs meet the strict fire-rating and hygiene requirements for commercial kitchens in high-rise malls and standalone restaurants.
Strategic KL Support: Based in Kuala Lumpur, we offer specialized installation for the Klang Valley's leading F&B operators, focusing on systems that are as clean on the outside as they are efficient on the inside.
