Abstract: A compression system, which includes an oil separator vessel, a suction separator supported by the oil separator, a compressor supported by the oil separator vessel, and a driver operatively connected to the compressor, wherein the driver is supported by the oil separator vessel for compressing fluids, gases, or combinations thereof.

Abstract: A heat exchanger for a compressor comprising a housing comprising a plurality of pass chambers, wherein each pass chamber comprises a plurality of tubes for contacting a hot fluid with a cooling media. At least one first flow nozzle introduces a first portion of the hot fluid into a first pass chamber. At least one second flow nozzle downstream of the first flow nozzle introduces a second portion of the hot fluid into at least one downstream pass chamber, forming a reduced rate of fluid flow in the first pass chamber and optimizing contact between the second portion of the hot fluid and the plurality of tubes, to form a cooled fluid. An outlet downstream of the second flow nozzle, in communication with a final pass chamber, is adapted for receiving the cooled fluid.
