Abstract: An improved oil reclamation device for removing solid contaminates and water or other volatile contaminates from the engine lubricating oils and hydraulic fluids. More particularly, this oil reclamation device relates to a unique combination evaporation chamber and filter housing, and to an improved filter assembly. A first feature of this oil reclamation device is the improved utilization of space through the efficient combining of the filter and evaporation chambers within one compact housing, which utilization brings the benefits of a compact installation with a minimum difficulty of installation. Another benefit of this design is the efficient use of engine oil to heat the evaporation surface evenly and effectively without the need of any additional heat source. This design eliminates cold spots on the evaporation surface and the need for potentially dangerous heating elements. Further, many different types of filter elements and filtration ratings may be used.
