At EKG (Malaysia) Sdn Bhd, we design and implement air-cooled chiller systems with advanced demand flow technology, engineered to intelligently adapt to real-time cooling demands. By integrating smart sensors, variable speed controls, and advanced algorithms, our systems achieve optimal performance with maximum energy efficiency, load responsiveness, and operational reliability.
An advanced demand flow system automatically modulates the performance of compressors, pumps, fans, and valves to match the precise cooling requirement at any given time. Unlike conventional systems that run at fixed speeds or fixed flow rates, this approach enables continuous adjustment based on load, occupancy, ambient conditions, and thermal demand.
1. Dynamic Compressor Load Modulation
Smart staging and unloading of compressors using demand-based control logic.
2. Variable Speed Drives (VSDs)
Installed on chilled water pumps, condenser fans, and even compressors for smooth, efficient operation across all loads.
3. Smart Expansion Valve Control
Electronic Expansion Valves (EXVs) adjust refrigerant flow precisely based on superheat and system conditions.
4. Real-Time Sensor Feedback
Integrates pressure, temperature, flow, and delta-T sensors across the system for continuous performance tuning.
5. Chilled Water Flow Optimization
Maintains desired temperature differential (ΔT) while reducing flow rates during low-load periods.
6. BMS Integration and Remote Monitoring
Seamlessly connects to Building Management Systems for remote access, alarms, and trend analysis.
