Kuala Lumpur | March 30, 2026 — While most of the city was still asleep, the EKG M&E team was already scaling the heights of Lot 10 Shopping Centre. Before the first light of sunrise hit the Bukit Bintang skyline, our technicians were on-site to conduct a critical maintenance operation: comprehensive rooftop ventilation duct cleaning and system hygiene.
Scope of Work: High-Level Duct Cleaning, Grease Deposit Removal, and Exhaust Fan Servicing
Timing is everything in retail M&E. To avoid any disruption to the mall's daily operations and to ensure the safety of pedestrians below, we scheduled this high-elevation work for the early morning hours. Working in the cool, pre-dawn air allows our team to perform intensive cleaning on the primary exhaust outlets without the heat of the midday sun—or the heat of active commercial kitchens—impacting the job.
Maintaining rooftop exhaust systems requires more than just a quick wipe-down. Our team implemented a deep-clean protocol:
Grease & Particulate Extraction: Over time, rooftop discharge points accumulate a thick layer of grease and environmental dust. Our team used specialized scrapers and industrial degreasers to strip the duct interiors back to the bare metal, significantly reducing fire hazards.
Exhaust Fan Housing Service: The large centrifugal and axial fans located on the roof were opened and inspected. We cleaned the fan blades (impellers) to ensure they remain balanced, preventing the vibrations that can lead to motor failure.
Louver & Mesh Clearing: We cleared out the external louvers and bird screens that often get clogged with debris. This simple but vital step immediately improves the static pressure of the entire building's ventilation system.
Integrity Inspection: Under the early morning work lights, we checked all exterior duct seals and weather-proofing. Any degraded sealant was replaced to ensure that rainwater cannot enter the ventilation shafts during KL’s heavy afternoon downpours.
Fire Risk Mitigation: By removing combustible grease deposits from the final exit points of the exhaust system, we’ve significantly bolstered the building’s fire safety profile.
Improved Efficiency: Clean ducts and balanced fans mean the ventilation system doesn't have to "fight" to push air out, leading to lower amp draw and reduced energy consumption.
Operational Continuity: By finishing before the sun came up, we ensured that Lot 10 was ready to "breathe" perfectly the moment the first shops opened their doors.
Based in Kuala Lumpur, EKG is your partner for high-stakes M&E maintenance. Whether it's a midnight repair or a pre-dawn duct cleaning at a landmark like Lot 10, we bring the technical rigor and discipline needed to keep Malaysia's commercial infrastructure in top shape.
Is your rooftop exhaust looking weathered or clogged? Don't wait for a breakdown or a fire hazard.
