HVAC chiller pump

HVAC Chiller Pump | Engineered Primary Circulation for Optimal Cooling by EKG (Malaysia) Sdn Bhd

The Critical Heart of Efficient Building Cooling Systems
An HVAC chiller pump is the essential component responsible for circulating water through your chiller's heat exchangers, enabling the entire cooling process. Its precise operation directly determines chiller efficiency, system stability, and overall energy consumption. EKG (Malaysia) Sdn Bhd provides expert HVAC chiller pump solutions—from hydraulic design and high-efficiency selection to professional installation and predictive maintenance—ensuring your cooling plant delivers reliable, cost-effective comfort.

Core Functions in HVAC Systems

• Evaporator Water Circulation: Moves chilled water from the chiller to Air Handling Units (AHUs) and Fan Coil Units (FCUs) throughout the building.

• Condenser Water Circulation: Circulates water between the chiller and cooling tower for effective heat rejection.

• System Pressure & Flow Management: Maintains design conditions for optimal heat transfer and equipment protection.

• Hydraulic System Stability: Ensures consistent operation in complex primary, secondary, or variable flow systems.

Signs Your HVAC Chiller Pump Needs Attention

• Reduced Cooling Capacity: Chiller struggling to meet building demand.

• High Energy Consumption: Unexplained increase in chiller plant electricity usage.

• Chiller Alarms: High or low evaporator/condenser pressure warnings.

• Unusual Pump Operation: Excessive noise, vibration, or visible leaks.

• Temperature Control Issues: Poor or fluctuating chilled water ΔT (temperature difference).

• Frequent Component Failures: Repeated seal, bearing, or coupling problems.
