For oil used in X-ray transformers and X-ray tubes you typically need two things: deep removal of dissolved moisture/gases (to prevent electrical breakdown) and clean, controlled vacuum filling/top-up for small volumes. GlobeCore’s CMM-0.4 / CMM-0.6 units are positioned specifically for X-ray machine oil purification, combining heat + vacuum dehydration/degassing with mechanical filtration to remove particles. For service work on compact HV assemblies, the GlobeCore UVD Vacuum Oil Filling Unit is a practical match: it prepares/degasses oil and supports vacuum filling/top-up for high-voltage ports, with small batch handling (30 L preparation, 4 L filling section).
