Pump for Cooling System | Industrial & HVAC Solutions by EKG (Malaysia) Sdn Bhd
The Critical Role of Pumps in Cooling
In any commercial or industrial facility, the cooling system is only as effective as the water moving through it. Whether you are operating a Water-Cooled Package Unit (WCPU), a centralized chiller plant, or an industrial process cooling loop, the pump is the "heart" that ensures heat is moved away from your equipment and rejected out of the building.
EKG (Malaysia) Sdn Bhd provides specialized engineering, installation, and maintenance for cooling system pumps, ensuring your facility stays operational even in Malaysia’s extreme humidity and heat.
Common Pump Types for Cooling Systems
1. Chilled Water Circulation Pumps
These pumps move refrigerant-cooled water from the chiller to the Air Handling Units (AHUs).
-
Primary Pumps: Maintain a constant flow through the chiller to prevent the evaporator from freezing.
-
Secondary Pumps: Distribute water to different zones, often using Variable Frequency Drives (VFDs) to save energy during low-demand hours.
2. Condenser Water Pumps
These are used in water-cooled systems to move heat-laden water from the condenser to the rooftop Cooling Tower.
-
They must handle higher temperatures and are often exposed to more debris, requiring robust suction strainers and high-durability mechanical seals.
3. Vertical Multistage Booster Pumps
Ideal for high-rise buildings, these pumps provide the high pressure (head) required to push cooling water to the top floors of a skyscraper or luxury condominium.
Key Technical Challenges in Cooling Pumps
Preventing Cavitation
In cooling systems, especially those with high-rise piping or hot condenser water, the risk of Cavitation is high. This occurs when water turns to vapor inside the pump, causing "pitting" on the impeller and loud, gravel-like noises. We perform NPSH (Net Positive Suction Head) calculations to ensure your pump runs smoothly without internal damage.
Managing Thermal Expansion
Cooling systems deal with temperature fluctuations that cause pipes to expand and contract. We ensure your pumps are installed with Flexible Connectors and are perfectly aligned using Laser Shaft Alignment to prevent pipe stress from cracking the pump casing.
Energy Efficiency (VFD Optimization)
Cooling demand changes throughout the day. A fixed-speed pump wastes massive amounts of electricity. We specialize in retrofitting cooling pumps with Intelligent Controllers that slow the motor down when demand is low, often reducing electricity costs by over 50%.
