2000L/H Disc Oil Separator Centrifuge Transformer Oil Purification 4kW Motor 380V Vacuum Dehydration Mobile Cart Design

2000L/H Transformer Oil Disc Oil Separator with Vacuum Dehydration

The HLSEP HL-DOS2000T is a mobile disc oil separator centrifuge with integrated vacuum dehydration, purpose-engineered for on-site transformer insulating oil purification. Combining centrifugal solids removal with vacuum moisture extraction, this compact cart-mounted system restores aged transformer oil to IEC 60422 standard specifications, extending transformer service life and preventing dielectric breakdown failures.

Key Features

• Integrated Vacuum Dehydration: Built-in vacuum chamber reduces dissolved water content to below 10 ppm and removes dissolved gases from insulating oil, restoring dielectric strength to ≥70 kV as required by IEC 60422 for service-aged transformer oil
• Mobile Cart Design: Compact footprint (1200 x 750 x 1350 mm) with heavy-duty locking casters enables easy transport between substation transformers, eliminating the need for permanent installation at each oil processing location
• Combined Treatment Technology: Centrifugal separation removes solid contaminants (carbon particles, cellulose fibers, metal wear debris) simultaneously with vacuum dehydration, providing complete oil reconditioning in a single processing pass
• 4kW Energy-Efficient Operation: Optimized motor and heating system minimizes power consumption during field operations, with 6kW electric oil heater maintaining optimal 60-70°C processing temperature for effective vacuum dehydration
• IEC 60422 Compliance: Designed and tested to meet IEC 60422:2013 mineral insulating oil maintenance guidelines, with validated performance for restoring oil parameters including dielectric strength, water content, acidity, and interfacial tension

On-Site Service Benefits

The HL-DOS2000T enables transformer oil reclamation without draining or transporting oil off-site, reducing maintenance downtime from weeks to days. The combined centrifugal-vacuum process achieves 2000L/H throughput, treating a typical 10MVA transformer oil volume (8000-12000L) in a single 4-6 hour processing session. Integrated oil sampling ports allow real-time dielectric strength verification during treatment.
