Oil coolers for oil-insulated power transformers and reactors are designed to manage the thermal performance of these electrical devices.

Air-Cooled: Uses fans to blow air over the cooling coils filled with oil. These are often used where water resources are limited.
Water-Cooled: Employs water as a cooling medium, which can be more efficient but requires a reliable water source.


 

Modern oil coolers can be designed to minimize environmental impact, using eco-friendly materials and efficient cooling methods.
