Abstract
The present invention monitors and removes contaminants from dielectric fluids by utilizing an apparatus having a chamber and tube configuration. The chamber encloses a plurality of tubes which include porous hollow fibers with an inert polymer coating. Conduits route the dielectric fluid to and from operative equipment. An atmosphere control device creates an atmospheric condition within the chamber that causes contaminants within the dielectric fluid to migrate through the tubes into the chamber, thereby producing refined dielectric fluid. The method of the present invention removes contaminants from a dielectric fluid. The dielectric fluid is routed from operative equipment and passes through tubes enclosed within a chamber. An atmospheric condition is created within the chamber to cause contaminants within the dielectric fluid to migrate into the chamber. A refined dielectric fluid is produced which is directed back to the operative equipment. The contaminants removed from the dielectric fluid may further be analyzed, monitored, have any moisture therein removed, or be vented to atmosphere.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
