In the industrial facilities of Kuala Lumpur and Selangor, a central vacuum system is more than just a cleaning tool; it is a critical utility for material recovery and factory hygiene. However, a poorly optimized duct network can lose up to 40% of its suction power due to friction and turbulence. CVS Duct Optimization involves the strategic application of fluid dynamics to minimize pressure drops, prevent clogs, and ensure that every inlet provides peak performance.
EKG M&E Sdn Bhd specializes in the engineering of high-efficiency vacuum networks, ensuring your facility complies with DOSH indoor air quality standards and the EECA 2024 energy mandates.
Optimizing a high-velocity vacuum system requires a departure from standard HVAC thinking. Here, air density and particulate momentum are the primary design drivers.
Friction Mitigation: We utilize industrial-grade PVC or Zinc-Plated Steel with ultra-smooth internal bores. Unlike standard piping, CVS-specific ducting has "flush-fit" joints to prevent internal ridges where debris can snag.
Tapered Mainlines: As branch lines enter the main header, the diameter must increase proportionally to maintain a constant Transport Velocity (typically 20–25 m/s). If the duct is too large, the air slows down and material drops out, causing a blockage.
Long-Radius Sweeps: Standard 90° elbows are banned in optimized vacuum systems. We utilize Long-Radius Sweeps (90° and 45°) to allow particulates to glide around turns without impacting the outer wall, which reduces both friction loss and abrasive wear.
Branch Entry (45° Wye Joints): Branch lines must enter the main header at a 45° angle or less in the direction of flow. This minimizes the "collision" of two air streams, maintaining the momentum of the captured particulates.
In a vacuum system, even a pinhole leak causes a "short circuit" that starves downstream inlets of suction.
Solvent/Thermal Fusing: For polymer systems, we utilize molecular welding to ensure the network is Airtightness Class 6 (ATC 6) compliant.
O-Ring Flanged Joints: For metal systems, we use heavy-duty flanged joints with recessed O-rings, providing a durable, vibration-resistant seal that holds high vacuum levels.
Variable Frequency Drives (VFDs): The single biggest energy saver. By monitoring system pressure, the VFD ramps the vacuum pump motor speed up or down based on how many inlets are currently open.
TNB Energy Savings: This "Demand-Control" approach can reduce your monthly TNB electricity bill by up to 50% compared to a constant-speed system.

Total 3D BIM Coordination: We model the vacuum path in 3D to ensure "clash-free" installation around existing electrical trays and fire suppression systems, prioritizing the straightest possible runs for the vacuum lines.
Minimum Transport Velocity (MTV) Validation: We calculate and test the air velocity at every inlet to ensure it meets the required threshold for your specific material (fine dust vs. heavy metal chips).
Regional Industrial Support: Based in Kuala Lumpur, we provide site audits and professional installations for semiconductor plants, food processing facilities, and high-precision machine shops across Malaysia.
