Wet Scrubber Duct Installation

Wet Scrubber Duct Installation by EKG M&E Sdn Bhd

In 2026, Wet Scrubber Duct Installation is a specialized mechanical requirement for facilities dealing with high-temperature kitchen exhaust, corrosive chemical fumes, or heavy grease loads. Under the Energy Efficiency and Conservation Act (EECA) 2024 and updated BOMBA regulations, the ductwork feeding a wet scrubber (such as a Hydro-Vent or water-wash system) must be engineered to handle both high-velocity air and constant moisture. For projects in Kuala Lumpur and Selangor, a poorly installed wet duct leads to "Corrosive Pitting" and "Liquid Seepage," which destroys building assets and degrades your 5-Star BEI.

At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to provide instrument-verified wet scrubber ducting. We ensure your system is liquid-tight, compliant with MS 1472, and optimized for a 5-Star Energy Intensity Label.

1. The Engineering Logic: Moisture and Pressure Management

Wet scrubber ducts differ from standard HVAC ducting because they must manage a "Two-Phase" flow—saturated air and liquid droplets.

• Material Integrity (SS316): Because wet scrubbers often utilize detergents or handle acidic cooking vapors, we utilize fully TIG-welded Stainless Steel 316. This grade provides superior resistance to chloride-induced pitting and crevice corrosion compared to standard GI or SS304.

• Liquid-Tight Velocity Control: We engineer the duct to maintain a "Transport Velocity" of 9.0 m/s to 12.0 m/s. This ensures that moisture remains suspended or is directed toward drainage points rather than pooling in the duct, which would otherwise create a "Static Pressure Choke."

• Lowering the BEI: Water mist in the duct increases air density and resistance. We utilize Variable Frequency Drives (VFDs) interlocked with Differential Pressure Transmitters. By modulating fan speed based on the real-time moisture load, we reduce energy waste, directly improving your Building Energy Index (BEI).

2. Specialized Wet Duct Installation Protocols

We follow a rigorous mechanical standard to ensure your facility meets BOMBA 2026 and DOSH benchmarks:

A. Anti-Corrosive Slope & Internal Drainage

All horizontal wet scrubber duct runs are installed with a minimum 1:100 slope toward a dedicated grease trap or drainage point. We integrate Deep-Seal Traps to prevent odors or ozone from leaking back into the kitchen while ensuring the duct remains free of stagnant, corrosive water.

B. BOMBA-Compliant Fire-Rating

Where wet ducts penetrate fire-rated walls, we apply SIRIM-certified Fire-Rated Wraps. Because these ducts are often moist, we utilize specialized non-absorbent wraps that maintain their fire-integrity (2 to 4 hours) even in high-humidity environments, protecting your building from thermal radiation.

C. Bio-Security & IAQ (DOSH 2026)

Wet ducting can be a breeding ground for tropical mold if not managed. Our installation includes UV-C Sterilization points within the duct to neutralize airborne pathogens. This maintains a sterile air path, satisfying the highest DOSH 2026 indoor air quality and food safety standards.

4. Why Professional Installation is Essential for 2026

• Meeting DBKL/MBSA Licensing: KL authorities now prioritize "Visible Steam" and "Odor" as key metrics. Our wet scrubber ducting ensures that the water-wash process is contained and effective, providing the technical proof required for smooth license renewals.

• Lowering TNB Maximum Demand: By eliminating "Moisture Clogs" and maintaining aerodynamically smooth internal surfaces, we ensure your Kitchen Exhaust Fan (KEF) operates at its peak efficiency. This secures your 5-star efficiency rating.

• Property Value Protection: Leaking wet ducts can cause catastrophic damage to a building’s structural slabs and electrical risers. Our liquid-tight, anti-corrosive installation protects your long-term real estate value.
