Professional Controlled Environment Ventilation by EKG M & E Sdn Bhd

In the specialized industrial and medical sectors of KL and PJ, a "Controlled Environment" is defined by more than just temperature. EKG M & E Sdn Bhd engineers ventilation systems that provide total mastery over Pressure, Particulate Count, and Pathogen Control. Whether you are managing a semi-conductor cleanroom, a pharmaceutical lab, or a sterile hospital suite, our systems ensure your environment stays within its defined ISO or clinical parameters.

Core Pillars of Controlled Ventilation

• High-Precision Room Pressurization

  We maintain strict pressure gradients between adjacent zones to prevent cross-contamination.

  • Positive Pressure: Used in cleanrooms and operating theaters to "push" air out, preventing dust and untreated KL air from entering when doors open.

  • Negative Pressure: Essential for labs or isolation wards to "trap" hazardous fumes or pathogens, ensuring they are only exhausted through high-safety filtration.

• Multi-Stage HEPA & ULPA Filtration

  Standard filters cannot meet controlled standards. We integrate H13/H14 HEPA filters (99.97% efficiency) or U15/U16 ULPA filters (99.999% efficiency) directly into the airflow path or via Fan Filter Units (FFUs).

• Laminar (Unidirectional) Airflow Design

  To prevent "turbulence" that can kick up settled dust, we design laminar flow systems. Air moves in a uniform, downward stream from the ceiling to floor-level extracts, effectively "sweeping" the room clean of particles in real-time.

• VFD-Driven Airflow Compensation

  As filters become saturated with particulates, their resistance increases. We utilize Variable Frequency Drives (VFDs) interlocked with static pressure sensors; the system automatically ramps up the fan speed to maintain the constant Air Change Rate (ACH) required for your cleanroom classification.

• UVGI Pathogen Neutralization

  In medical or food-grade environments, we install Ultraviolet Germicidal Irradiation (UVC) lamps within the AHU. This provides a continuous "kill rate" for airborne bacteria and mold spores, preventing biofilm buildup on cooling coils.
