In the tropical industrial zones of KL and Selangor, managing the "Heat Reservoir" that forms beneath a factory or warehouse roof is a critical M&E task. Without effective Industrial Roof Ventilators, internal temperatures can soar to 10°C above the outdoor ambient temperature, leading to worker heat stress, equipment failure, and inventory degradation.
EKG M&E Sdn Bhd specializes in engineering both passive and powered rooftop ventilation systems, ensuring your facility remains compliant with DOSH (JKKP) safety standards.
As an HVAC and Clean Air Specialist, we select the ventilation method based on your building's "Static Pressure" requirements and specific heat load.
These are high-capacity fans designed to mechanically pull hot air and industrial fumes out of the building.
The Benefit: They provide a guaranteed Air Change Rate (ACR) regardless of external wind conditions.
VFD Integration: We equip these with Variable Frequency Drives (VFDs) to modulate speed based on internal temperature sensors, significantly reducing TNB electricity costs during cooler periods.
A continuous vent installed at the highest point of the roof slope that utilizes the "Stack Effect."
The Physics: As air heats up inside the factory, it becomes buoyant and rises. The ridge vent provides a natural exit point, pulling cooler air in through low-level louvers.
These "whirlybirds" use the kinetic energy of the wind to create a vacuum that extracts air from the attic or ceiling void.
The Benefit: Zero operating cost. However, for large-scale industrial heat loads, these are often paired with powered systems to ensure consistent airflow in the Klang Valley’s frequent "still air" conditions.
A roof ventilator is only as effective as the air it can replace. We focus on total building physics:
Building Pressure Management:
To prevent "Negative Pressure"—which sucks in humid KL air and street dust through loading bays—we balance rooftop exhaust with Make-up Air (MUA) units. We aim for a slight Positive Pressure to keep your production zone clean.
Weatherproofing & Waterproofing:
Given Malaysia's intense monsoon rains, we utilize specialized Pitch Pockets and industrial-grade flashing. This ensures that while air moves out, not a drop of water enters your facility, protecting your M&E assets and inventory.
Fire Safety (BOMBA) Interlock:
Our powered ventilators are integrated with the building's fire alarm system. In a fire event, they can be programmed to act as Smoke Spill Fans, clearing evacuation routes for staff.
| Feature | Passive Ridge Vents | Powered Roof Extractors |
| Energy Cost | Zero. | Varies (VFD Optimized). |
| Airflow Volume | Weather dependent. | Consistent & Guaranteed. |
| Maintenance | Minimal (No moving parts). | Low (Scheduled motor/belt checks). |
| Heat Removal | Steady / Continuous. | Rapid / High-Intensity. |
Airflow Balancing and Commissioning: We perform a professional Duct Traverse (if ducted) and Air Velocity Mapping to prove your facility is achieving its design Cubic Meters per Hour (CMH).
Total System Integration: We ensure your rooftop assets are synchronized with your Fresh Air Filtration and internal HVLS Fans for a complete cooling solution.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide turnkey design, structural mounting, and scheduled maintenance for logistics hubs, manufacturing plants, and central kitchens.
