In any centralized cooling system, the HVAC Circulation Pump is the engine that drives thermal energy transfer. Its primary job is to move chilled water or condenser water through a closed-loop network, connecting the heat source (chiller) to the heat emitters (AHUs/FCUs) or the heat rejection point (Cooling Tower). EKG (Malaysia) Sdn Bhd provides specialized engineering services to ensure these pumps operate at peak hydraulic efficiency, maintaining the delicate balance of your building's climate.
These pumps move refrigerant-cooled water from the chiller evaporator to the building’s Air Handling Units.
Primary Pumps: Ensure a constant, safe flow through the chiller to prevent the evaporator from freezing.
Secondary Pumps: Often controlled by VFDs to deliver water to specific zones based on real-time cooling demand.
Essential for Water-Cooled Package Units (WCPU) and water-cooled chillers, these pumps move heat-laden water to the rooftop cooling tower for atmospheric rejection.
Common in industrial processes and luxury hospitality, these circulators maintain a steady flow of hot water for climate control or domestic use.
The seal is the most common point of failure. We utilize Silicon Carbide and Tungsten seals designed to withstand the thermal expansion and chemical treatments used in Malaysian industrial water loops.
To prevent energy-sapping turbulence, we provide Dynamic Balancing for impellers. We also replace worn wear rings to maintain the tight internal clearances required for high pump head pressure.
Noise in the pump room is usually a sign of bearing fatigue. We replace worn bearings with premium SKF/FAG units and perform Laser Shaft Alignment to eliminate the vibration that leads to premature failure.
We help facilities transition from fixed-speed pumping to Variable Frequency Drive (VFD) control. By allowing the pump to slow down during low-occupancy hours, we can reduce your HVAC energy consumption by up to 30-50%.
Our technicians follow international engineering protocols for all mechanical and electrical repairs, ensuring your high-value assets are handled with technical precision.
Located in the heart of the industrial sector, we provide quick on-site troubleshooting to resolve leaks, noise issues, or "no-flow" emergencies before they affect tenant comfort.
