ABSTRACT:
An apparatus for removing impurities from lubricating oil comprising a container having a filter positioned in the lower end thereof with an evaporator plate positioned above the filter. The lubricating oil enters the container through an inlet opening formed in the lower end thereof with the oil being passed upwardly through the filter. The oil is dispersed or redistributed at the lower end of the evaporator plate so that the oil is moved to the center thereof and moved upwardly through a central opening. The evaporator plate has a plurality of annular concentric tiers provided on its upper end so that the oil passing through the upper end of the central opening in the evaporator plate flows downwardly and outwardly over the concentric tiers. A ring-shaped heating element is positioned in the container and extends around the upper end of the evaporator plate at the periphery thereof for heating the oil passing downwardly over the concentric tiers. The container has a cover positioned on the upper end thereof and has an oil outlet conduit extending from the upper end thereof.
