Abstract: A refrigeration system includes a vapor compression loop and a purge system in communication with the vapor compression loop. The purge system includes at least one separator for separating contaminants from a purge gas provided from the vapor compression loop to the separator. The at least one separator has a vertical orientation.

Abstract: A support for tube-and-fin assemblies in a radiator comprising a single support which is securable to multiple tube-and-fin assemblies in a single row and which is interlockable with respect to similar supports interconnected with rows of tube-and-fin assemblies in front of and/or behind that row.

Abstract: An air-to-air aftercooler including a first core assembly configured to receive intake air and cool the intake air. The first core assembly can include a first heat exchange portion configured to cool the intake air, a first inlet configured to receive the intake air, a second heat exchange portion configured to cool the intake air, a second inlet configured to receive the intake air, and a first common tank joining the first heat exchange portion and the second heat exchange portion and configured to output the intake air. The air-to-air aftercooler can also include a second core assembly configured to receive the intake air from the first common tank, and further cool the intake air.
