Abstract: Equipment and methods are provided for combining with a typical heat exchanger having numerous fin tubes, the combination allowing the containment of cleaning fluid used to clean fin tubes with high pressure liquid cleaning devices in which cleaning fluid is discharged into one end of each fin tube and out the other. An enclosure is attached to an opened end of a heat exchanger having U-shaped fin tubes, the enclosure having cleaning tool access portions for separately exposing each of at least two pluralities of the fin tubes entry ends, while continuing to cover the remaining fin tube pluralities, and the fin tube exit ends. Fluid splashed at the cleaning fluid entry end of the fin tubes and cleaning fluid exiting the fin tubes is captured and drained by the enclosure. Alternatively, a second enclosure captures exiting cleaning fluids in heat exchangers having straight fin tubes and two openable ends.

Abstract: Equipment and methods are provided for combining with a typical air cooler having numerous fin tubes, the combination allowing the containment of cleaning fluid used while cleaning the fin tubes with high pressure liquid cleaning devices in which cleaning fluid is discharged into one end of each fin tube and out the other. Two enclosures are attached to each end of the air cooler, with one enclosure having cleaning tool access portions for separately exposing each of at least two pluralities of the fin tubes while continuing to cover the remaining fin tube pluralities. Cleaning fluid splashed at the cleaning fluid entry end of the air cooler is captured and drained by the first enclosure, while cleaning fluid exiting the fin tubes at the cleaning fluid discharge end of the air cooler is captured and drained by the second enclosure.
