An oil conditioner is provided for removing impurities from oil, such as water, fuel and glycol, to increase engine life and efficiency. An evaporator assembly includes an upper plate, a lower plate, with a heater unit sandwiched between the two. To increase the efficiency of the evaporator assembly, materials are selected so that the upper plate thermal conductivity property is greater than the lower plate thermal conductivity property; and, optionally, the lower plate includes a reflective surface to direct thermal radiation toward the upper plate. This unique design enables oil conditioning with reduced power consumption and improved heating compared to existing technology.

A filter element (10) for a liquid medium such as fuel, having a filter medium (16) which is arranged in an annular manner and a venting arrangement (30), having a first vent channel (60), connected at the intake end to the pre-filtration side (26) of the filter element (10), a vent tube (32) which extends away from the upper end plate (12) and which has at one end an inlet opening (34) and at the other end an outlet opening (36) for fluidic connection of the vent tube (32) to a vent stub of a filter housing, or a vent tube portion for connection to a vent tube of a filter housing, which portion extends away from the upper end plate (12) axially in the direction of the lower end plate (14) and has an inlet opening (34) at one end.

The invention relates to a method for treating process fluids, such as those which are produced when a process liquid is separated into different process gases using an electric current in an electrolysis cell (10), comprising at least one fluid circuit in which at least one of the process gases is contained in the process liquid, thereby forming the process fluid, wherein at least one fluid storage tank (22) is provided as part of the fluid circuit. The invention is characterized in that the fluid storage tank (22) is equipped with at least one filter device (24), by means of which the process fluid is cleaned of any possible particulate contamination and simultaneously the contained process gas is separated from the process fluid while the process liquid is retained.
