Chiller Flow Control and Demand-Based Operation – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we offer smart chiller flow control and demand-based operation solutions that transform your cooling system into a high-performance, energy-efficient setup. By matching chilled water and refrigerant flow to actual building or process load in real-time, our system ensures peak efficiency, improved reliability, and significant energy savings—without compromising cooling performance.

What Is Demand-Based Chiller Operation?

Demand-based operation is a control strategy that continuously adjusts the chiller’s output—including compressor staging, chilled water flow, fan speed, and refrigerant flow—based on real-time demand conditions. Instead of operating at full capacity all the time, the system modulates flow intelligently to maintain stable temperature and pressure with minimum energy input.

Core Components of Our Flow Control System

• Variable Speed Drives (VSDs)
  Used on pumps and fans to modulate flow rates based on demand, reducing unnecessary energy usage.

• Electronic Expansion Valves (EXVs)
  Fine-tune refrigerant flow for precise control of superheat and cooling capacity.

• Delta-T Optimization
  Maintains optimal temperature difference across the evaporator and condenser, avoiding over-pumping or undercooling.

• Smart Controls and Algorithms
  Adjust system operation automatically using real-time sensor data (pressure, flow, temperature) and predictive logic.

• Integrated BMS Compatibility
  Seamlessly connects with Building Management Systems for centralized monitoring, control, and analytics.
