An overhaul of a warehouse exhaust system is more than just swapping out old motors; it is an opportunity to recalibrate your building’s "respiratory system" for better energy efficiency and DOSH (JKKP) compliance.
At EKG M&E Sdn Bhd, we specialize in transforming aging, noisy, and inefficient ventilation into high-performance assets using modern control logic and aerodynamic blade designs.
Old fans often suffer from "Blade Fatigue" and inefficient motor windings.
The Upgrade: We replace heavy, rusted steel blades with Cast Aluminum Aerofoil Blades. These move a higher volume of air ($CMH$) while reducing the "Amperage Draw" on your electrical system.
Motor Insulation: We utilize Class H insulated motors that can withstand the 33°C+ ambient temperatures of a typical Selangor warehouse roof without "tripping."
Running fans at 100% 24/7 is a major waste of TNB electricity.
The Logic: We install VFDs that allow the fans to ramp down during rainy periods or night shifts. This eliminates "Inrush Current" (the spike in power when a fan starts) which extends the lifespan of the motor bearings and belts by up to 50%.
A common failure point in KL warehouses is the Automatic Shutter. If they are stuck open, they leak cooled air; if stuck shut, they burn out the motor.
The Solution: We install lightweight, corrosion-resistant louvers that provide a weather-tight seal against tropical storms while offering zero resistance to the exhaust stream when active.
As an HVAC and Clean Air Specialist, an overhaul allows us to fix systemic issues like Negative Pressure.
Make-up Air (MUA) Balancing:
If your exhaust is too strong without enough intake, your warehouse becomes a vacuum. This sucks in street dust and humid air through every crack. We recalibrate the fan speeds to maintain a slight Positive Pressure shield.
Thermal Destratification Interlock:
We often interlock the exhaust fans with HVLS Fans. The HVLS fan pushes the heat down from the ceiling, and the exhaust fan "spills" it out, creating a continuous "Thermal Flush."
| Component | Old System Status | Post-EKG M&E Overhaul |
| Airflow Volume | Declining due to belt slip. | 100% Design Capacity (CMH). |
| Energy Usage | Fixed Speed (High Cost). | VFD Optimized (Low Cost). |
| Noise Levels | High-frequency vibration. | Balanced / Whisper-quiet. |
| Reliability | Prone to "tripping." | Interlocked & Automated. |
Airflow Mapping and Commissioning: Post-overhaul, we use calibrated anemometers to prove the new Air Change Rate (ACR) meets your operational requirements.
BOMBA Compliance: We ensure that replaced fans are correctly interlocked with the Fire Alarm System for emergency smoke spill functionality.
Klang Valley Strategic Support: Based in Kuala Lumpur, we offer turnkey removal, structural retrofitting, and long-term "Clean Air" maintenance contracts.
