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.
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.
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.
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
