For hydraulic oil purification, GlobeCore offers vacuum dehydrators (CMM series) and fine filtration systems (CFU series). They remove water and solid particles, improving oil cleanliness and service life. Please specify oil viscosity, contamination type, and required capacity for proper selection.

Another factor that can influence the choice of a hydraulic oil purification unit is whether the maintenance will be performed with the equipment in operation. Offline purification allows the oil to be processed while the hydraulic system continues working, helping remove moisture, dissolved gases, and fine particles without interrupting the production. This approach is particularly beneficial for industrial facilities where unexpected downtime is costly. The photo below shows an example of a compact purification unit suitable for routine oil conditioning and preventive maintenance.

The photo matches the compact CMM-LT style units used for routine oil conditioning and preventive maintenance; these portable vacuum-dehydrators are designed to run offline (circulating oil from the reservoir while the hydraulic system stays in service), so you can remove moisture, dissolved gases and fine particulates without costly shutdowns. In practice the CMM-LT family (models such as CMM-1.0LT up to CMM-8LT) delivers 0.6–8 m3/h, brings outlet cleanliness to about ISO 14/12 (NAS 6), reduces moisture to ≤10 ppm and volumetric gas to ≤1.5%, and is compact and easy to operate with minimal operator training.

If your reservoir oil starts with moderate moisture (up to roughly 100 ppm) a CMM-LT offline unit is a good first choice for preventive maintenance and polishing; for higher moisture levels consider zeolite adsorption units (CP-130/CP-260) for deeper dehydration, or a coalescing-filter plant (CMM-CF) when free water is extreme. When installing offline equipment, match unit flow to reservoir size, plumb with isolation/bypass connections, monitor outlet particle and moisture readings, and follow cartridge/zeolite maintenance intervals to keep the system effective.
