The evaporator motor in an air-cooled chiller circulates refrigerant, ensuring efficient heat exchange and maintaining cooling performance. Over time, electrical wear, overheating, insulation breakdown, and mechanical fatigue can cause motor winding failure, resulting in higher energy consumption, reduced cooling efficiency, and potential system breakdown.
Motor rewinding is a cost-effective solution to restore performance, improve efficiency, and extend motor lifespan. EKG (Malaysia) Sdn Bhd provides expert services for reliable, energy-efficient, and long-lasting motor operation.
