Kitchen Duct Exhaust Riser Systems by EKG M & E Sdn Bhd
In high-rise buildings, hotels, and shopping malls across KL and PJ, the Exhaust Riser is the backbone of the kitchen ventilation system. It is a vertical "super-highway" that transports grease-laden air from individual kitchens to the rooftop discharge point. EKG M & E Sdn Bhd specializes in the design, installation, and maintenance of these critical vertical shafts, ensuring they meet the high-pressure and fire-safety demands of multi-story structures.
Key Features of Our Kitchen Exhaust Riser Services
-
Heavy-Gauge Vertical Construction Risers must support their own weight and withstand high stack pressures. We use 1.6mm (16-gauge) black steel or stainless steel with continuous liquid-tight longitudinal welds to prevent grease seepage into building cavities.
-
Fire-Rated Shaft Integrity We ensure all risers are enclosed in fire-rated shafts or wrapped with 2-hour fire-rated ceramic blankets. This prevents a kitchen fire on one floor from spreading vertically to other levels of the building.
-
Integrated Grease Collection "Tees" At the base of every vertical riser, we install specialized collection "Tees" and drain plugs. This allows liquefied grease to be trapped and drained safely rather than pooling at the bottom of the shaft.
-
High-Static Pressure Fan Coordination Vertical risers create significant "stack effect" and air resistance. We perform complex M&E calculations to select high-static upblast fans that can pull smoke effectively across 10, 20, or 30 stories.
-
Telescopic Expansion Joints To account for the intense heat of commercial cooking, we install expansion joints that allow the metal ductwork to expand and contract without warping or breaking the fire seals at floor penetrations.
-
Strategically Placed Access Panels As per NFPA 96, we install fire-rated access doors at the top and bottom of the riser and at every change of direction, allowing for mandatory high-pressure cleaning and inspection.
-
Vibration and Thermal Isolation We use heavy-duty spring hangers and thermal stand-offs to ensure the riser does not transfer mechanical noise or radiant heat into the building's structural walls or occupied spaces.
