At EKG M&E Sdn Bhd, we offer advanced demand flow controller solutions for air-cooled chillers, designed to intelligently manage and optimize the flow of chilled water and refrigerant in real-time. By dynamically adjusting flow rates based on cooling demand, our demand flow controller enhances energy efficiency, reduces equipment wear, and ensures stable operation across varying load conditions.
A demand flow controller is an integrated control system that continuously monitors and adjusts key parameters—such as chilled water flow, compressor load, fan speed, and expansion valve operation—based on the actual cooling demand. It serves as the brain behind smart chiller operation, maintaining performance without unnecessary energy consumption.
Real-Time Flow Optimization
Continuously adjusts pump and fan speeds using VSDs to match system demand.
Integrated Sensor Feedback
Utilizes data from temperature, pressure, and flow sensors to fine-tune refrigerant and water flow.
Load-Adaptive Compressor Control
Coordinates compressor staging and unloading to prevent short cycling and reduce energy spikes.
Intelligent Expansion Valve Management
Adjusts TXVs or EXVs to maintain optimal superheat and refrigerant flow rates.
System-Wide Communication
Seamlessly integrates with Building Management Systems (BMS) for centralized monitoring and control.
Energy Optimization Algorithms
Implements logic to maintain the lowest kW/ton ratio at all times.
Reduces energy usage by 10–40%, especially during part-load operation
