The motor in an air-cooled chiller powers compressors, condenser fans, and evaporator systems, ensuring efficient cooling performance. Over time, mechanical wear, overheating, insulation degradation, and electrical imbalances can cause motor inefficiencies, increased power consumption, and potential failures.
Load testing and rewinding help detect performance issues, restore efficiency, and extend the motor’s operational lifespan. EKG (Malaysia) Sdn Bhd provides professional air-cooled chiller motor load testing and rewinding services, ensuring maximum reliability, energy savings, and long-term durability.
