Warehouse Ventilation Performance Testing by EKG M&E Sdn Bhd
In the industrial landscape of Kuala Lumpur and Selangor, a ventilation system is only as good as its measured output. Warehouse Ventilation Performance Testing is the M&E process of verifying that your fans, louvers, and ductwork are delivering the specific Air Change Rate (ACH) and Static Pressure required for DOSH (JKKP) and BOMBA compliance.
EKG M&E Sdn Bhd utilizes high-precision instrumentation to move beyond "estimation" and provide a data-backed audit of your building's respiratory health.
1. The Core Testing Protocols
As an HVAC and Clean Air Specialist, we perform a multi-point diagnostic to map the airflow behavior within your facility.
A. Duct Traverse & Face Velocity Testing
We measure the actual speed of air moving through your intake louvers and exhaust ducts.
-
The Physics: Using a calibrated Vane Anemometer, we take readings across a grid pattern (traverse) to calculate the average velocity ($m/s$).
-
The Calculation: $Velocity \times \text{Area} = \text{Total Airflow (CMH)}$. This confirms if your fans are actually hitting their nameplate capacity or if "Belt Slip" and "Motor Drag" are causing losses.
B. Building Pressure Differential Test
To maintain a clean warehouse, you need Positive Pressure.
-
The Process: We use a Digital Manometer to compare the internal pressure against the external atmospheric pressure.
-
The Target: We look for a slight positive offset (typically $10\text{--}25$ Pa). This ensures that when loading bays open, air pushes out, creating a "Shield" against KL street dust and humidity.
C. Airflow Mapping & "Dead Zone" Detection
We identify areas where air has become stagnant, leading to "Heat Pockets" or moisture buildup.
-
The Method: We utilize Non-Toxic Smoke Tracers to visually confirm the airflow path. This reveals if air is "Short-Circuiting" (moving directly from intake to exhaust without mixing) or if racking is blocking the flow of your HVLS fans.
2. VFD & Electrical Load Auditing
Performance isn't just about air volume; it’s about electrical efficiency. We audit your Variable Frequency Drives (VFDs) to ensure they are optimized for your TNB bill.
-
Inrush Current Analysis: We measure the power spike during fan start-up. If it’s too high, we reprogram the "Ramp-up" logic to protect the motor windings.
-
Harmonic Distortion Check: In large warehouses with multiple VFDs, we check for electrical "noise" that can cause control panel failures or interfere with other sensitive machinery.
