Commercial Kitchen Pollution Control Units (PCU) by EKG M&E Sdn Bhd
In the dense urban landscape of Kuala Lumpur and Selangor, where high-end restaurants often share space with luxury residences and Grade-A offices, managing kitchen emissions is a legal and social necessity. A Pollution Control Unit (PCU) is a high-capacity, multi-stage filtration housing designed to strip grease, smoke, and odors from the exhaust stream before it reaches the atmosphere. EKG M&E Sdn Bhd specializes in the engineering and BOMBA-compliant installation of PCUs for the most demanding F&B environments.
The Anatomy of an EKG M&E PCU
A PCU is not a single filter; it is a series of mechanical and electronic "scrubbers" housed in a heavy-duty, weather-proof cabinet.
1. Stage 1: Mechanical Pre-Filtration (G4/MERV 8)
This stage captures the largest grease particles and debris to protect the more sensitive downstream components.
-
Service Goal: Regular replacement prevents the system from "choking" and dropping the Air Change Rate (ACR).
2. Stage 2: Electrostatic Precipitator (ESP)
The "heart" of the PCU. The ESP uses high-voltage ionization to give smoke and fine grease mist an electrical charge, causing them to "stick" to collection plates.
-
Efficiency: Modern ESP cells remove up to 95-98% of smoke and sub-micron grease particles.
3. Stage 3: High-Efficiency Bag or HEPA Filters (Optional)
For facilities with strict environmental permits, we add a medical-grade filtration layer to catch any remaining microscopic particulates.
4. Stage 4: Activated Carbon or UV-C Ozone
The final stage targets odors (VOCs).
-
Activated Carbon: Large trays of porous carbon trap odor molecules.
-
UV-C/Ozone: Ultraviolet light breaks down grease and odor molecules through photolysis and ozonolysis, ensuring the air discharged at the rooftop is neutral and clean.
Engineering Integration for the Klang Valley
As an HVAC and Clean Air Specialist, we ensure the PCU is perfectly synchronized with your building's M&E infrastructure:
-
Variable Frequency Drive (VFD) Modulation: PCUs create significant "Static Pressure" (resistance). We program the VFD to monitor the pressure drop across the filters and automatically ramp up the Rooftop Exhaust Fan to maintain constant suction over the cooking range.
-
Kitchen Make-up Air (MUA) Balancing: A PCU-driven system pulls a massive volume of air. We calibrate your Fresh Air Supply to match, preventing "Whistling Doors" and ensuring your dining room remains at a "Positive Pressure" to keep out KL street dust.
-
BMS and Fire System Interlock: Our PCUs are integrated with your Building Management System (BMS) for real-time monitoring. In the event of a kitchen fire, the PCU is interlocked to shut down or bypass to ensure the safety of the smoke spill system.
PCU Performance and Maintenance Matrix
