Transformer Oil Dry-Out Systems

Pro-Filtration is your source for all things related to filtering and purifying transformer oil. We offer several options for filtering and storage of transformer oil, both mobile and stationary.

Our systems include a large diameter filter vessel with swing bolt closure.  The large diameter filter element is ideal for maximum water and particulate retention (up to 2 gallons of water) and filtration down to 0.4 micron.  The swing bolt closure makes for convenient filter changes. The industrial filter vessel insures years of maintenance free service.

Storage tanks are usually required.  We offer easy to understand piping manifold and four way valve options so oil can be pulled from the transformer, processed and returned back to the transformer without having to disconnect hoses.

Trailers are built in house using high quality components to insure maximum safety and long term reliability.   Each trailer is custom engineered and built to the application. Storage tanks are baffled. Tank capacity is considered when sizing axles and structure.  Safety is our primary concern.

Dry-out filter cartridges are manufactured from specially formulated medias to remove carbon and moisture from transformer and insulating oils.  Microglass filter media is layered with high quality water absorptive medias and cellulose and are available in micron efficiencies from 1µm down to 0.4µm.  These filters are typically used on lower voltage transformers, circuit breakers, tap changers and switch gears.
