Chiller Performance Tuning with Demand Flow – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we offer expert chiller performance tuning with demand flow control, designed to unlock the full potential of your cooling system. By aligning chilled water and refrigerant flow with real-time load requirements, our demand flow tuning service enhances energy efficiency, reduces wear on components, and ensures consistently reliable performance under all operating conditions.

What Is Demand Flow-Based Chiller Tuning?

Demand flow-based tuning involves optimizing the interaction between chillers, pumps, fans, and control systems to ensure that cooling output precisely matches building or process demand. Instead of running at fixed speeds or static setpoints, the system uses dynamic, real-time feedback to adjust how much and how fast chilled water and refrigerant are circulated—maximizing performance while minimizing energy waste.

Our Performance Tuning Services Include

• System Assessment & Data Logging
  We begin with a detailed audit of your chiller’s current operating conditions, load profile, and inefficiencies.

• Delta-T Optimization
  We fine-tune the chilled water temperature differential to improve heat exchange and avoid over-pumping.

• Pump & Fan Speed Calibration
  Variable speed drives (VSDs) are adjusted to match system demand and eliminate unnecessary power usage.

• Compressor Load Balancing
  Optimizing compressor staging, unloading, and modulation to avoid short cycling and improve part-load efficiency.

• Expansion Valve Adjustment
  Calibration of thermostatic or electronic expansion valves (TXVs/EXVs) for precise refrigerant metering.

• Control Logic Tuning
  Modification of chiller PLC or BMS control sequences to support demand-based operation, temperature resets, and smarter start/stop cycles.

• Post-Tuning Testing & Reporting
  System is re-evaluated under real load conditions with performance benchmarking and full reporting.
