For this type of application, the correct solution is a vacuum dehydration oil purification unit, since hydraulic oils in such systems typically suffer from water ingress and fine contamination. These systems remove water, gases, and solid particles in one process, which is critical for maintaining equipment reliability. In practice, GlobeCore units like CMM-4/7 or CMM-6/7 follow this same principle – combining heating, filtration, and vacuum dehydration – and are widely used for hydraulic systems, turbomachinery, and power generation equipment.
