In the industrial corridors of Kuala Lumpur, Selangor, and Nilai, Lean-Phase (Dilute-Phase) Conveying is the most common method for transporting lightweight, non-abrasive materials such as plastic resins, flour, wood chips, and fine chemicals. In this system, material is "suspended" in a high-velocity air stream where the air-to-material ratio is high. Because the material moves at high speeds (typically 18–35 m/s), the design of the ducting is critical to prevent product degradation, pipe wear, and energy-robbing pressure drops.
EKG M&E Sdn Bhd specializes in the engineering of high-velocity lean-phase networks, ensuring your facility complies with DOSH safety standards and the EECA 2024 energy mandates.
Lean-phase systems rely on kinetic energy. If the air velocity drops, the material will "saltate" (fall out of the air stream), leading to immediate and costly blockages.
In lean-phase conveying, turbulence is the enemy of efficiency.
Flush-Fit Joints: We utilize specialized Pneumatic Couplings or Clamp-Together systems that ensure pipe ends meet perfectly. This eliminates the internal ridges or gaps found in standard ducting, preventing material from snagging and creating a "snowball effect" that leads to a clog.
Elimination of Fasteners: We strictly avoid internal screws or rivets. Every internal obstruction creates a "vortex" that saps air velocity and increases the load on your blower.
Because the material is moving at high velocity, every turn in the ducting represents a point of impact.
Long-Radius Sweeps: We utilize elbows with a Centerline Radius (CLR) of 3D to 10D. This allows the suspended material to glide around turns using centrifugal force rather than "smashing" into the outer wall, which preserves the physical integrity of your product.
45° Lateral Entries: When merging multiple lines into a main header, we utilize 45° (or shallower) entries to ensure the two high-speed streams integrate without causing back-pressure.
As a specialized M&E contractor, EKG ensures your lean-phase system supports both plant uptime and the bottom line:
TNB Energy Efficiency (VFD Calibration): Lean-phase blowers are significant electricity consumers. By utilizing ultra-smooth internal walls and Variable Frequency Drives (VFDs), we minimize frictional resistance. This allows your system to maintain the required transport velocity at the lowest possible power frequency, directly reducing your monthly TNB electricity bill.
Static Electricity Dissipation: Moving dry particulates at high speeds through plastic or ungrounded metal pipes creates massive static charges. We ensure the entire ducting network is electrically bonded and grounded, preventing sparks that could trigger a dust explosion.
Hermetic Leak Prevention: Whether the system is positive pressure (pushing) or negative pressure (vacuum), we utilize high-compression gaskets or welded seams to ensure the system is Airtightness Class 6 (ATC 6) compliant. This ensures 100% of the air volume is used for material transport rather than being wasted through leaks.

Total 3D BIM Coordination: We model your conveying paths in 3D to ensure "clash-free" installation around existing electrical trays and structural beams, prioritizing the straightest possible runs to maximize system efficiency.
Minimum Transport Velocity (MTV) Validation: We perform Pitot Tube Traverses and Static Pressure audits to prove your system maintains the required kinetic energy to keep your specific material in flight.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional site audits and installations for food processing, plastic extrusion, and chemical manufacturing plants across Malaysia.
