The hydraulic oil chiller is a critical device for maintaining stable operation of hydraulic systems. It uses forced refrigeration to precisely control the operating temperature of hydraulic oil, effectively preventing efficiency loss, seal aging, and component damage caused by excessive oil temperature. Widely used in injection molding machines, die-casting machines, and hydraulic power units, it significantly improves system stability, extends hydraulic oil service life, and ensures continuous production and machining precision.
