Frequently Asked Questions

Can vacuum oil purifiers handle heavy lubricating oils?

Yes, our vacuum lubrication oil purifiers are specifically designed to process heavy-grade oils including ISO VG 220, 320, and higher, removing water, gases, and particulates without degradation.

How does transformer oil dehydration work?

Transformer oil is heated and sprayed into a high-vacuum chamber where moisture and gases are evaporated and removed by vacuum pumps, restoring dielectric strength and insulation properties.

What is the difference between single-stage and double-stage purifiers?

Double-stage units have an additional vacuum chamber for deeper dehydration and degassing, achieving lower moisture levels (<10 ppm) and higher vacuum (<5 Pa), ideal for high-voltage transformers.

Do you offer explosion-proof models?

Yes, we manufacture explosion-proof versions of turbine oil purifiers, lubrication oil purifiers, and centrifugal separators suitable for hazardous environments (ATEX/IECEx compliant).
