For high-end restaurants, hotels, and central kitchens—especially those in "low-level" discharge areas or luxury malls in KL and PJ—standard extraction is not enough. EKG M & E Sdn Bhd specializes in the design and installation of Ecology Units (also known as Pollution Control Units). These multi-stage filtration systems treat kitchen exhaust to a "clean air" standard, removing smoke, grease, and intense cooking odors before the air enters the surrounding environment.
Stage 1: High-Capacity Pre-Filtration
Before reaching the sensitive components, the air passes through heavy-duty synthetic or metal mesh filters. This captures large grease particles and prevents "loading" on the secondary stages, extending the lifespan of the entire unit.
Stage 2: Electrostatic Precipitator (ESP) Cells
Utilizing high-voltage ionization, the ESP stage charges microscopic smoke and grease particles, pulling them onto collection plates. This stage is critical for achieving "invisible" exhaust discharge.
Stage 3: High-Efficiency Bag or HEPA Filters
For kitchens requiring medical-grade air discharge, we include secondary mechanical filtration. These filters trap any remaining fine particulates that may have bypassed the ESP, ensuring 99% filtration efficiency.
Stage 4: Activated Carbon Gas-Phase Filtration
Odors from spices, onions, and charbroiling are gaseous and cannot be "caught" by standard filters. We use deep-bed activated carbon pellets that chemically adsorb odor molecules, ensuring the exhaust smells neutral to neighbors.
Stage 5: Integrated UV-C/Ozone Oxidation
As an optional final polish, UV-C lamps break down organic compounds via photolysis. This not only kills bacteria but further neutralizes odors through the production of controlled ozone ($O_3$).
System Monitoring & Safety Interlocks
Our Ecology Units feature pressure sensors that alert staff when filters are clogged. They are also interlocked with the kitchen's fire suppression system to automatically shut down in the event of a hood fire.
DOE & DBKL Compliance
Urban local authorities (like DBKL and MBPJ) increasingly mandate Ecology Units for restaurants in residential or "street-level" areas. We ensure your system meets all Department of Environment (DOE) clean air requirements.
M&E Engineering for Static Pressure
Ecology Units create significant resistance. As M&E specialists, we calculate the exact fan power needed to "push" air through multiple filter stages without losing suction at the kitchen hood.
Total Lifecycle Maintenance
An Ecology Unit is only effective if serviced. We provide scheduled chemical washing for ESP cells and timely carbon media replacement, ensuring your unit doesn't become a bottleneck for your kitchen.
