Air-Cooled Chiller Variable Flow Optimization – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we provide specialized variable flow optimization services for air-cooled chillers, helping you maximize efficiency, reduce energy costs, and extend equipment life by dynamically adjusting flow based on real-time demand. Variable flow systems enable chillers to respond intelligently to fluctuating load conditions—delivering the right amount of chilled water at the right time, without waste.

What Is Variable Flow Optimization?

Variable flow optimization is the process of fine-tuning the chilled water and refrigerant flow within a chiller system using variable speed drives (VSDs), smart controls, and sensor feedback. This allows pumps, fans, and compressors to operate at optimal speeds, especially during part-load conditions, ensuring efficient operation across all demand levels.

Key Features of Our Optimization Services

• Dynamic Pump and Fan Control
  Adjusts speed in real-time to maintain ideal chilled water flow and condenser airflow.

• Setpoint Reset and Control Logic Tuning
  Optimizes chilled water temperature setpoints and control sequences based on actual system usage.

• Delta-T Optimization
  Maintains proper temperature differential across evaporators to prevent underperformance or short cycling.

• Smart Valve and Flow Sensor Integration
  Utilizes electronic expansion valves (EXVs), balancing valves, and flow meters for fine control.

• Load-Based Compressor Modulation
  Matches compressor operation to system demand, reducing energy consumption during low-load periods.

Benefits of Variable Flow Optimization

• Saves 15–40% in energy consumption, especially in partial load conditions

• Enhances chiller performance, responsiveness, and stability

• Reduces wear and tear on mechanical components

• Supports efficient staging of multiple chillers
