Chilled water pumps are the heart of any HVAC system—but most run at fixed speed, constantly delivering design flow even when cooling demand drops. This wastes enormous energy, subjects motors to unnecessary wear, and drives up operating costs year after year. Variable speed chilled water pumps automatically modulate flow to match real-time building load, reducing pump energy consumption by 30–50% while improving temperature control and reducing mechanical stress. Without this upgrade, facilities bleed money through oversized, constant-speed operation. EKG (Malaysia) Sdn Bhd retrofits, supplies, and commissions variable speed chilled water pump solutions for commercial, institutional, and industrial HVAC systems.
Our variable speed chilled water pump solutions serve:
Office Towers & Commercial Buildings
Hospitals & Healthcare Facilities
Hotels & Mixed-Use Developments
Universities & Educational Campuses
Data Centers & Mission-Critical Cooling
District Cooling & Central Plant Systems
Excessive Pump Energy – 100% flow delivered for 60% load conditions
Poor Differential Pressure Control – Overpressurisation at part load
Valve Dependence – Relying on control valves to kill excess pressure
Mechanical Wear – Constant high-speed operation shortens motor and bearing life
Temperature Instability – Inconsistent supply to AHUs and FCUs
High Starting Current – DOL starting stresses electrical infrastructure
