In the precision manufacturing and chemical processing hubs of Selangor and Kuala Lumpur, general room ventilation is often insufficient for protecting workers from hazardous airborne contaminants. EKG M&E Sdn Bhd provides Custom-Engineered Source Capture Enclosures, designed to contain and extract pollutants at the exact point of generation. By surrounding the "source" with a targeted aerodynamic barrier, we prevent the migration of toxic fumes, dust, and heat into the wider factory environment, ensuring strict compliance with DOSH Occupational Health standards.
Unlike generic hoods, our source capture enclosures are custom-fabricated to fit your specific machinery, tool, or workstation. We focus on the "Capture Velocity"—the speed at which air must move to overcome cross-drafts and pull contaminants into the exhaust stream—to ensure 100% containment with minimal energy waste.
We specify the enclosure geometry and material (Acrylic, Stainless Steel, or PVC) based on the visibility requirements and chemical nature of your process.
1. Robotic Welding and Laser Cutting Cells
High-intensity thermal processes release fine metallic fumes and ozone that pose severe respiratory risks.
Integrated Fume Booths: We design modular panels with high-temperature glass or specialized acrylic viewports. These enclosures are interlocked with the robot’s cycle, ensuring the exhaust fan ramps up the moment the arc is struck.
Spark Arrestor Integration: To prevent fire in the ducting, we integrate spark traps directly into the enclosure’s transition module, cooling particulates before they enter the main exhaust run.
2. Chemical Weighing and Mixing Stations
Processes involving fine powders or volatile liquids require a "Quiet Air" environment to prevent material loss while ensuring worker safety.
Laminar Flow Hoods: We utilize a "Sash-Style" enclosure design that allows the operator to work comfortably through a physical barrier. The airflow is engineered to move horizontally away from the operator's breathing zone.
Chemically Inert Surfaces: For acid or solvent mixing, the enclosure is fabricated from Grade 316 Stainless Steel or Acid-Resistant PVC, preventing surface degradation and ensuring easy decontamination.
3. Electronics Assembly and Soldering (Point-of-Use)
Micro-soldering releases lead fumes and rosin flux that must be extracted without cooling the soldering iron tip.
Articulated Snorkel & Mini-Enclosures: For intricate manual work, we provide localized "Micro-Enclosures" that surround the workpiece, providing high-velocity extraction in a small footprint.
ESD-Safe Construction: All electronic enclosures are built with Electrostatic Discharge (ESD) safe materials to protect sensitive PCBA components from static damage during the extraction process.
As an industrial M&E specialist, EKG ensures the enclosure is an integrated part of your production line:
Aerodynamic "Face Velocity" Calibration:
We calculate the necessary Face Velocity (m/s) based on the "Enclosure Opening" area. Our engineers use thermal anemometers to verify that the airflow is uniform across the entire opening, eliminating "dead spots" where fumes could escape.
Automation and Sensor Interlocking:
To reduce TNB electricity costs, we integrate VFD-driven fans with occupancy or motion sensors. The enclosure only maintains full extraction volume when a worker is present or the machine is active, providing significant energy savings compared to constant-volume systems.
Ergonomic "Human-Factor" Design:
A safety enclosure only works if the operator uses it. We design our enclosures with adjustable lighting, clear lines of sight, and ergonomic access points, ensuring that safety protocols do not hinder production speed or worker comfort.
| Feature | Generic Canopy Hood | EKG Source Capture Enclosure |
| Capture Efficiency | 60% - 70% (Prone to drafts) | 95% - 100% (Total Containment) |
| Air Volume Required | High (Dilution based) | Low (Targeted at Source) |
| Worker Protection | Partial | Absolute (Breathing Zone Shield) |
| Energy Consumption | High (Massive fan load) | Low (Optimized CFM) |
| Customization | Standard Sizes | Bespoke to Tool/Machine |
Physics-Based Design: We don't just "install a box." We model the thermal buoyancy and particle trajectory of your process to ensure the enclosure geometry is aerodynamically sound.
Compliance Documentation: We provide the airflow verification reports and face-velocity logs required for DOSH (JKKP) safety audits and factory licensing.
Strategic Selangor Support: Based in Kuala Lumpur, we provide professional site audits for "smoky" or "smelly" factory zones, offering custom enclosure retrofits to bring your facility up to 2026 health standards.
