An air conditioner including a frame, a fan operable to generate an airflow that moves in an airflow direction, and a first heat exchanger including a first end adjacent the air inlet, a second end adjacent the air outlet, an air inlet face that extends between the first end and the second end, an air outlet face that extends between the first end and the second end and faces opposite the air inlet face, and a longitudinal axis that extends through the first end and the second end between the air inlet face and the air outlet face. The heat exchanger is configured to transfer heat between the airflow and a cooling medium. A first heat exchanger angle is defined between the longitudinal axis of the heat exchanger and the airflow direction, and the first heat exchanger angle can be between about 3 degrees and about 20 degrees.

A unique compressor system includes a compressor and an oil separation system. The oil separation system may include an oil separator element in fluid communication with a compressor discharge; an oil reservoir in fluid communication with the oil separator element that receives and accumulates separated oil; an oil-level controlled valve to control the flow of the oil from the oil reservoir to the compressor; and a check valve in fluid communication with the oil reservoir, the check valve being structured to prevent a reverse oil flow into the oil reservoir. A unique oil separation system, includes an oil separator element; an oil reservoir to accumulate separated oil; an oil-level controlled valve to control the flow of the from the oil reservoir; and a check valve to prevent a reverse oil flow into the oil reservoir.

A condensate separator device for a compressor arrangement for the production of compressed air having a separator housing that has a compressor-side inlet connection and an outlet connection for discharging the dehydrated compressed air. A base-side drainage valve is provided for releasing the condensate, which has collected in the separator housing, into the surrounding environment via a release opening. The valve is pneumatically-piloted seat valve able to be controlled by an electro-pneumatic control valve, and this electro-pneumatic control valve of the drainage valve is arranged outside the separator housing and connected to a pilot connection of the drainage valve via a control pressure-line.

A system for capturing dust during the movement of sand between a container and a fracing blender includes a conveyor system having a lateral portion for transporting sand discharged from the container, a lifting portion for lifting sand received from the lateral portion, and a spout for discharging sand received from the lifting portion into a bin of the fracing blender. An enclosure encloses a substantial length of the lateral portion of the conveyor, with portions of the enclosure disposed above and along opposing sides of a belt of the lateral portion of the conveyor system. A manifold is supported on the ground and is coupled in fluid communication with a flexible conduit, which has an inlet disposed in an area proximate a discharge end of the spout. An air system is coupled in fluid communication with the manifold and the flexible conduit for drawing air through the inlet of flexible hose to capture dust around the discharge end of the spout. A collapsible cover is disposed over the discharge end of the spout and the bin of the blender.

Air filter and silencers comprise an air filter element having an annular body with openings at opposed ends. A top is attached over one of ends, has an outer flange sealed to the element, and includes a central section extending across the air filter element end. The top central section has a convex-shaped geometry with a radius of curvature projecting outwardly and away from the air filter element. The top central section includes a sound deadening material directed towards the air filter element. The top central section has a radius of curvature greater than the radius of an inside diameter of the air filter element. The air filter and silencer is used with an air filter assembly that includes a housing removably attached to the air filter and silencer, and that has an internal chamber projecting axially into the air filter and silencer with a sound deadening material disposed therein.

A device for exhaust gas treatment in an exhaust system of an internal combustion engine, in particular in a motor vehicle, includes an electrically heatable honeycomb body through which an exhaust gas can flow. The honeycomb body is disposed in a casing tube and has at least one current-conducting structure with electric insulation for voltages greater than 24 V. A current-generating pulsed voltage is applied to the structure to heat the honeycomb body. It is thus possible for heating elements in the exhaust-gas flow to be powered by an on-board electrical system voltage of for example 48 V. A method for operating the honeycomb body is provided with which, even at operating voltages greater than 24 V, the generation of heat in the electrically heatable honeycomb body can be kept in a desired range by adjustment of a pulse width and/or repetition frequency of the pulsed voltage.

Method of collecting used cooking oil includes extracting used cooking oil from at least one deep fryer to a container, storing and separating said used cooking oil within the container which is located within the cooking area. The oil from the deep fat fryer is periodically pumped to the container and allowed to settle. The unwanted sludge is then tapped off into a portable container and the wanted oil is pumped to an exterior transportation container. The container is triangular shaped with rear walls converging into a corner of the cooking area and a diagonal front face with side flanges and a bottom flap such that it is located in the corner of an interior wall of a building and contains the pipes and plumbing.

Fouling rate inhibition for a hydrogenation reactor. A hydrocarbon hydrogenation method comprises passing a liquid feedstream through a magnetic field to separate magnetically susceptible particles, and introducing the magnetically lean stream into a fixed catalyst bed under hydrogenation conditions to saturate carbon-carbon double bonds in the hydrocarbon. Also, a hydrogenation reactor system comprises a magnetic conditioning zone, an inlet flow path to introduce a magnetically lean stream from the magnetic conditioning zone into a fixed catalyst bed and an outlet flow path from an outlet end of the catalyst bed to withdraw reactor effluent.
