These are designed as versatile Transformer Oil Filter units for field or factory use. These units use high capacity multi-stage electric oil heaters, large capacity vacuum pumps with external connections and 3 stage particulate filtration. Flow rates up to 6000 litres/hr are available. These units are used by ESI to do Vacuum filling of transformers. These units are supplied with Vaisala in-line moisture meters to constantly monitor oil moisture content and plant performance.
6000 liter/hour purifier unit on trailer
These filter units are simple to use, plug into a standard domestic power supply yet will remove free, emulsified and dissolved moisture in oil from 50ppm to <10ppm in a single pass. Particles are also removed to < 0.4 micron ensuring the electrical properties of insulating oil always meet specification. An in-line moisture meter comes standard with the filter unit so maintenance crews can re-energise field equipment with confidence. Versions of this unit are also available for Lubrication...

On-line Vacuum Dry-out units allow drying of transformer windings while the transformer remains in normal service. Maintaining low moisture levels in the cellulose ensures the transformer is less likely to fail due to shock loadings, such as lightning or through faults, and insulation material is not degraded through chemical reaction with moisture.
ESI on-line Tap-changer Filter Units remove moisture and particulates in the insulating oil, maintaining the electrical properties of the oil and therefore reduce arcing during contact break. Cost savings in maintenance, spares and a significant increase in system reliability soon recover initial installation costs. All units are installed using high pressure stainless steel tube and fittings to ensure ultra high reliability and long life.
