High Velocity Kitchen Exhaust Design by EKG M & E Sdn Bhd
In high-demand commercial kitchens—such as those featuring heavy charbroiling, wok ranges, or 24/7 operations—standard extraction often fails. EKG M & E Sdn Bhd specializes in High Velocity Kitchen Exhaust Design, focusing on "Capture and Containment" (C&C). By increasing the air velocity at the hood aperture and within the ductwork, we ensure that the most stubborn grease-laden thermal plumes are evacuated before they can escape into the kitchen or dining area.
Key Principles of High Velocity Exhaust Design
-
Aperture Velocity Optimization
We design hoods with specialized "slotted" or "high-velocity" filters. By reducing the open area of the filter face, we increase the air intake speed, creating a powerful suction zone that "pulls" smoke from a greater distance above the cooking surface.
-
Minimum Transport Velocity ($V_{min}$)
To prevent grease from settling and "pooling" in horizontal ducts, we design for a minimum transport velocity of 1,500 to 1,800 FPM (Feet Per Minute). This keeps grease particles suspended in the airstream until they reach the filtration system or the fan.
-
Venturi-Effect Plenum Design
Our custom-fabricated plenums utilize the Venturi effect to accelerate air as it enters the ductwork, minimizing turbulence and "dead zones" where grease and heat typically accumulate.
-
High-Static Pressure Fan Selection
High-velocity systems create significant internal friction. We utilize heavy-duty, belt-driven centrifugal upblast fans or utility sets specifically rated to overcome high static pressure ($P_s$) while maintaining consistent airflow.
-
Integrated Air-Curtain Technology
We often incorporate "Compensating Hoods" that introduce a high-velocity curtain of make-up air around the perimeter of the hood. This acts as a physical barrier, "pushing" the thermal plume upward into the extraction zone.
-
Tapered Duct Transitions
To maintain velocity throughout the "exhaust highway," we use long-tapered transitions rather than abrupt changes in duct size. This reduces static regain and ensures that the air speed remains constant from the hood to the roof.
-
Noise and Vibration Attenuation
High-velocity air can be noisy. We integrate acoustic silencers and double-skin insulated ducting in sensitive areas to ensure that the increased performance doesn't compromise the dining environment's acoustics.
Why Choose EKG M & E Sdn Bhd for High Velocity Design?
-
Fluid Dynamics Expertise
As an M&E engineering firm, we use precise calculations to ensure your system doesn't just "suck air" but moves it strategically. We balance velocity against energy consumption to find the "sweet spot" of performance.
-
Strategic Support in KL & PJ
We have extensive experience designing high-performance systems for some of the busiest mall-based and hotel kitchens in Kuala Lumpur and Petaling Jaya, where space is tight and performance is non-negotiable.
-
BOMBA & NFPA 96 Compliance
High-velocity systems must be built to higher structural standards. We ensure all welds, hangers, and fire-rated wraps meet the most stringent safety codes to handle the increased internal pressures.
