At EKG M&E Sdn Bhd, we specialize in variable demand flow air-cooled chiller design, engineered to deliver maximum cooling efficiency, flexibility, and operational cost savings. By incorporating smart flow control strategies, variable speed technologies, and real-time load responsiveness, our designs ensure that your chiller system adapts precisely to changing cooling demands, without energy waste.
Variable demand flow design enables an air-cooled chiller system to automatically adjust chilled water and refrigerant flow rates based on real-time thermal load. Unlike fixed-flow systems, this approach uses variable speed drives (VSDs), electronic expansion valves (EXVs), and adaptive control logic to reduce energy use, optimize component operation, and improve overall performance across part-load and full-load conditions.
Variable Speed Pumps and Fans
Reduce power consumption by modulating flow and airflow in response to cooling demand.
Compressor Load Modulation
Use scroll, screw, or inverter-driven compressors with smart staging for efficient operation at any load level.
Electronic Expansion Valves (EXVs)
Regulate refrigerant flow for precise cooling control and better part-load performance.
Delta-T Optimization
Maintain the ideal temperature differential across the evaporator to avoid over-pumping and ensure efficient heat exchange.
Sensor-Driven Controls
Monitor temperature, pressure, and flow in real-time to continuously optimize system operation.
BMS Integration
Seamless compatibility with building automation systems for remote control, monitoring, and analytics.
