Abstract: A heat exchanger includes a core having a plurality of tubes, each tube having a tube inlet and a tube outlet, and the tube inlets define an inlet plane and the tube outlets define an outlet plane. The tubes are spaced from one another for receiving a second fluid therebetween, for heat transfer between the first and second fluids. A jacket is provided adjacent the core for use in containing the second fluid, and the jacket comprises a jacket inlet for passage of the second fluid en route to the core. The jacket extends between the inlet plane and the outlet plane, and the jacket inlet is offset from the inlet plane towards the outlet plane. The heat exchanger further comprises a deflector arrangement for directing a flow of second fluid from the jacket inlet towards the inlet plane prior to entering the core.

Abstract: A tube type heat exchanger includes a core includes multiple tubes, a header plate defining an array of apertures in which said tubes are received, and a coolant jacket arranged about said core. The header plate includes a body defining a central region and an edge region circumferential to said central region. The central region defines said array of apertures. The edge region includes a flange. The header plate is connected to the coolant jacket via first and second contact areas between the header plate and the coolant jacket. The flange is outboard of the coolant jacket. The first contact area is between the flange and the coolant jacket; and the second contact area is inboard of the first contact area.

Abstract: An air compressor unit having an enclosure with a base. A motor is rigidly mounted to the base, and the motor drives both an airend and an impeller. The airend is pivotally mounted with respect to the base. The airend is directly connected to a horizontal separator tank, and the separator tank supports the airend. The airend and separator tank comprise a single integrated unit, and the separator tank is pivotally mounted to the base. The motor is a dual shafted motor having a drive side shaft and a non-drive shaft extending from opposite ends of the motor. A drive system is coupled to the drive side shaft and transfers power from the motor to the airend. The drive system is a belt and pulley system, and the airend is pivoted with respect to the motor to adjust belt tension. The impeller is coupled to the non-drive side shaft.

Abstract: A separator tank assembly comprising a cast hollow tank and a cast lid. The cast hollow tank has a closed end and an open end having a first opening and a second opening. The cast lid has a first passage configured for fluid communication with the tank first opening and a second passage configured for sealed fluid communication with the second opening. The first passage is formed with an integral port configured to receive a pressure control valve and the second passage is formed with an integral port configured to receive an oil filter and wherein the tank is configured such that air having undergone primary separation flows through the first opening and oil within the tank flows through the second opening.
