AC Chiller Water Pump

AC Chiller Water Pump | Precision Engineered Primary Circulation by EKG (Malaysia) Sdn Bhd

The Vital Component for Efficient Chilled Water Circulation
The AC chiller water pump is the critical heart of your chilled water system, responsible for circulating water between the chiller's evaporator and the building's cooling coils. Its precise operation directly determines chiller efficiency, cooling capacity, and overall system energy consumption. EKG (Malaysia) Sdn Bhd provides expert solutions for AC chiller water pumps—from hydraulic design and selection to installation, maintenance, and optimization—ensuring your cooling plant operates at peak performance.

Core Functions in Chiller Systems

• Primary Circulation: Moves chilled water through the chiller evaporator and out to Air Handling Units (AHUs) and Fan Coil Units (FCUs).

• System Pressure Maintenance: Ensures adequate pressure is available throughout the distribution network.

• Heat Transfer Enablement: Critical for efficient heat exchange at the chiller evaporator and cooling coils.

• Flow Regulation: Works with control valves to manage variable cooling demands across the building.

Signs Your Chiller Water Pump Needs Attention

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

• High Chiller Energy Consumption: Increased kWh usage without increased cooling load.

• Chiller Alarms or Trips: High or low evaporator pressure warnings.

• Unusual Pump Noises: Cavitation sounds, grinding, or excessive vibration.

• Water Temperature Issues: Inadequate ΔT (temperature difference) across the evaporator.

• Visible Leaks or Corrosion: Around pump seals, connections, or casing.
