Air-Cooled Chiller Flow Modulation System – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we offer advanced flow modulation systems for air-cooled chillers, designed to intelligently manage and regulate chilled water and refrigerant flow based on real-time load conditions. Our solutions ensure your system delivers precise cooling while reducing energy use, compressor wear, and operational costs—especially in variable load environments.

What Is a Flow Modulation System?

A flow modulation system dynamically adjusts the flow rate of chilled water and refrigerant through the chiller components to match the actual cooling demand. It uses variable speed drives (VSDs), modulating valves, and intelligent controls to continuously optimize flow across evaporators, condensers, and compressors.

Key Features of Our Flow Modulation System

• Variable Speed Pump and Fan Control
  Automatically modulates flow and airflow to reduce energy use during part-load conditions.

• Electronic Expansion Valve (EXV) Integration
  Ensures precise refrigerant metering based on superheat and system pressure readings.

• Real-Time Load Tracking
  Adjusts flow rates in response to building occupancy, process loads, or time-of-day schedules.

• Delta-T Monitoring and Adjustment
  Maintains optimal temperature differentials across the evaporator for efficient heat transfer.

• Integrated with Chiller Controller or BMS
  Seamlessly communicates with existing control systems for coordinated operation.

Benefits of a Flow Modulation System

• Improves energy efficiency by avoiding over-pumping or overcooling

• Enhances chiller performance and response time

• Reduces compressor cycling and system wear

• Supports stable supply air or chilled water temperatures

• Adapts to changing load conditions without manual intervention

• Contributes to green building certifications and energy audits

Ideal Applications
