An oil chiller is a type of cooling system designed to regulate the temperature of oils used in various industrial processes and machinery. It is commonly used in situations where the oil absorbs heat from mechanical equipment, such as in hydraulic systems, CNC machines, gearboxes, compressors, and even in certain food processing or pharmaceutical applications. The primary purpose of an oil chiller is to ensure the oil remains at an optimal temperature for efficient operation, preventing overheating and maintaining consistent performance.
