  • Patent number: 10330363
    Abstract: A lubricant separator is disclosed. The lubricant separator can cause lubricant which is entrained with a heat transfer fluid (e.g., a lubricant—heat transfer fluid mixture) to coalesce and fall (e.g., via gravity) into a bottom portion of a lubricant tank assembly. The lubricant separator can also reduce a velocity of the lubricant—heat transfer fluid mixture as it enters the lubricant tank assembly. The velocity reduction can, for example, reduce an amount of splashing of the lubricant that occurs as the lubricant—heat transfer fluid mixture enters the lubricant tank assembly. The velocity reduction can also, for example, be relatively more conducive to lubricant droplets falling into the bottom portion of the lubricant tank assembly as the flow of the heat transfer fluid is provided to a heat transfer fluid return conduit of the lubricant tank assembly.

The first chamber (6) has a cyclone (60) for pre-dehumidifying the gas, from which dirt particles and fluids can be discharged into a third chamber (14) of the housing (2). The housing (2) is composed of an upper housing part (8) with the second chamber (10) forming the filter chamber, a middle housing part (4) with a first chamber (6) having the cyclone (60), and a lower housing part (12) forming the third chamber (14), that can be clamped together by at least one tensioning bolt (32), forming a closed pressure vessel.

  • Patent number: 8657896
    Abstract: A separator is disclosed. The separator includes a gas/liquid separator vessel, an enclosure, a coalescer and a demister. The gas/liquid separator vessel has a first end, a second end, a first inlet, a first outlet, and a first separation chamber. The first inlet can be adjacent to the first end. The enclosure is positioned within the first separation chamber of the liquid separator vessel. The enclosure has a second inlet, a second outlet, a drain positioned therebetween, and a second separation chamber. The second inlet can be directed towards the first end of the gas/liquid separator vessel. The second separation chamber defines a flow path for a gas stream in which the flow path passes sequentially through the second inlet, second separation chamber and the second outlet. The coalescer is positioned in the second separation chamber to intercept the flow path of the gas stream.

  • Publication number: 20130232927
    Abstract: The invention relates to a separating device for separating a multiphase medium, comprising a cyclone separating device (1) that provokes an at least partial distribution of at least two phases of said medium with the formation of a vortex flow for the medium. The invention is characterized in that each phase, which has a lower density compared to the respective other phase, is separated from said other phase and can be guided out of the separating device by means of a collecting device (35, 37).

  • Patent number: 8529669
    Abstract: The present invention relates to a method and device for the purpose of filtering particulate laden air exiting a rooftop from a commercial kitchen or other high particulate laden air exhaust. By positioning a filter at a distance from the air exhaust exit in such a manner that the air flow is reflected off the filter a substantial portion of the particulate matter is filtered out of the air without substantially obstructing the flow from the exhaust preventing problems that might be caused from creating back flow in an exhaust system.

    Abstract: A water separator reduces a water content of an air stream, which is used in an HVAC unit for a vehicle. The water separator includes a diverter wall and an adjacent wall spaced from the diverter wall to define an air passage. The diverter wall has a terminal end extending into the air passage for changing a direction of the air stream to reduce the water content of the air stream. A filter assembly is disposed through a receiving slot in the diverter wall and is within the air passage downstream of the terminal end.

  • Publication number: 20130087044
    Abstract: A liquid phase separator assembly permits the separation of a high pressure gas phase from a liquid phase through a controlled expansion of the gas phase with the successful agglomeration and separation of the liquid phase all within a single unit. This complete separation of the gas phase facilitates the removal of the gas by venting. The complete separation of the liquid phase optimizes the solvent recovery/cleaning by processing the liquid phase through an engineered media. The liquid phase separator assembly incorporates an internal chamber for decompression and separation as well as for containing a media for purifying the liquid phase, thus reducing overall cost and complexity.
