Demand Flow HVAC Chiller Control System – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we deliver intelligent demand flow HVAC chiller control systems designed to optimize how your chiller plant operates under variable load conditions. Our advanced control solutions ensure your HVAC system delivers the right amount of cooling at the right time, resulting in lower energy use, improved thermal comfort, and extended equipment life.

What Is a Demand Flow HVAC Chiller Control System?

A demand flow chiller control system automatically adjusts key HVAC components—such as chillers, pumps, fans, valves, and expansion devices—based on real-time demand. Using dynamic feedback loops, variable speed technology, and smart control algorithms, the system fine-tunes performance to reduce waste and improve system responsiveness under partial and full load conditions.

Key Features of Our Control System

• Real-Time Load Matching
  Adjusts chiller capacity, pump flow, and fan speed to match building or process demand instantly.

• Variable Speed Drives (VSDs) Integration
  Modulates pump and fan speeds for chilled water and condenser systems, reducing power consumption.

• Smart Compressor Staging
  Optimizes when and how compressors start, stop, or unload based on system load and efficiency curves.

• Delta-T Optimization
  Maintains ideal chilled water temperature differentials for maximum heat transfer and efficiency.

• Sensor-Based Feedback Control
  Uses flow, pressure, and temperature sensors to continuously fine-tune operations.

• Expansion Valve Modulation (EXV/TXV)
  Controls refrigerant flow accurately for better part-load performance.

• BMS and IoT Compatibility
  Fully integrates with Building Management Systems and remote monitoring platforms for centralized control and analytics.

Benefits of Demand Flow HVAC Chiller Control

• Up to 30–50% energy savings in partial load scenarios
