Import Double-Stage Highly Effective Vacuum Insulating — Buy in Bulk from Supplier in China

The Double-Stage Highly Effective Vacuum Insulating Oil Purification Plant is a industrial-grade system designed to remove moisture, dissolved gases, and particulate contaminants from aged or degraded transformer insulation oil. It operates using two sequential vacuum chambers to achieve deep dehydration and degassing, with a processing capacity suitable for large-scale power transformers and substations. The system includes a closed-loop filtration circuit and a control panel with real-time monitoring of vacuum pressure and oil temperature.

The core components are constructed from stainless steel and high-grade carbon steel, selected for corrosion resistance in continuous operation. The double-stage vacuum system typically achieves residual pressures below 100 Pa, a standard benchmark for high-purity insulation oil treatment. The filtration stage employs multi-layer depth filters capable of capturing particles down to 1 micron, consistent with IEC 60475 guidelines for transformer oil cleanliness. The unit is engineered for 24/7 operation in industrial environments with ambient temperatures up to 40°C.

This equipment is primarily purchased by utility companies, transformer manufacturers, and maintenance contractors servicing high-voltage power infrastructure. Buyers typically require units capable of processing 500 to 5,000 liters per hour, depending on transformer size. Trade terms are available on request, including FOB and CIF shipping from Chongqing port. Packaging is standard industrial crate with moisture barriers. Lead time and minimum order quantities must be confirmed directly with the supplier.
