In a traditional HVAC system, pumps often run at a constant speed regardless of the actual cooling demand. Intelligent Pump Control changes this by integrating sensors and Variable Frequency Drives (VFDs) to allow the pump to "think." By continuously monitoring system variables like pressure and temperature, the controller adjusts the motor speed in real-time to meet the exact needs of the building.
EKG (Malaysia) Sdn Bhd specializes in deploying these smart systems to transform standard mechanical loops into responsive, energy-saving assets.
Pressure-on-Demand: As cooling valves in the building close, the system senses the pressure rise and slows the pump down. This ensures the furthest zones still get cooling without wasting energy on the floors that don't need it.
Temperature Balancing: The system monitors the temperature of the water returning to the chiller. If the water is returning too warm or too cold, the pump adjusts its speed to ensure the most efficient heat transfer possible.
Flow-to-Demand Logic: By communicating with your Building Management System (BMS), the pump can run at a fraction of its power during low-occupancy hours (such as nights or weekends), leading to immediate utility savings.
Significant Energy Savings: Because of the way centrifugal pumps work, a small reduction in speed leads to a massive drop in power use. Reducing speed by just 20% can often cut your pumping electricity costs by nearly half.
Whisper-Quiet Operation: Slowing the water flow eliminates the "rushing" or "whistling" sounds in pipes and reduces mechanical vibration in the pump room, creating a better environment for tenants.
Extended Equipment Life: "Soft-starts" and lower average running speeds mean less wear and tear on mechanical seals, bearings, and pipe joints, reducing your long-term maintenance costs.
Automatic Fault Detection: Smart controllers can detect issues like "dry-running" or a seized impeller and alert our team before the building loses cooling.
VFD Retrofitting & Tuning: We don't just install a drive; we tune the internal logic to ensure the pump operates smoothly without "hunting" or erratic speed changes.
Sensor Calibration: We perform site audits to place pressure sensors at the most effective points in your building to ensure 100% cooling coverage.
BMS Integration: We configure your smart pumps to talk to your central control system, providing you with real-time data on flow rates and energy health.
We understand the complex relationship between the chiller, the AHUs, and the pumps. Our ISO-certified procedures ensure that your high-value mechanical assets are handled with technical precision, helping your facility save money while staying cool.
