At EKG M&E Sdn Bhd, we design and implement advanced demand flow systems for air-cooled chillers to help building owners and facility managers achieve maximum energy efficiency, cooling performance, and operational reliability. Our system dynamically adjusts chilled water and refrigerant flow in real time based on actual cooling demand—ensuring your chiller plant operates smarter, not harder.
A demand flow system uses smart sensors, control logic, and variable speed technology to automatically modulate the performance of key chiller components—pumps, fans, compressors, and expansion valves—in response to load fluctuations. This approach ensures that your system supplies only the necessary cooling output, significantly reducing energy waste while maintaining precise temperature control.
Variable Speed Drives (VSDs)
Installed on pumps and condenser fans to reduce energy consumption during part-load operation.
Compressor Load Optimization
Controls compressor staging, unloading, or modulation to match demand efficiently.
Delta-T Optimization
Maintains the ideal chilled water temperature differential to improve heat exchange and reduce over-pumping.
Smart Refrigerant Control
Uses Electronic Expansion Valves (EXVs) for precise refrigerant flow management.
Sensor-Driven Control Logic
Integrates real-time data from flow, temperature, and pressure sensors to adjust operations dynamically.
BMS Integration
Compatible with major Building Management Systems for centralized monitoring and control.
Up to 30–50% energy savings depending on load variability
