A cleaning device is configured to access and remove fluid from and dry a moat region defined by a hub of a medical connector, thereby minimizing the potential for bacterial growth in the hub. The cleaning device takes the form of an absorbent block which can be inserted into the moat by extending about a central male fitting and into a gap between the male fitting and the inner wall of a female hub of the medical connector. In a preferred embodiment of the invention, the block takes the form of a tubular cylinder particularly configured for use on ENFit medical connectors wherein the absorptive feature of the cleaning device can be employed alone or in combination with another cleaning tool used to first remove any existing dried and caked solution in the hub before removing residual cleaning fluid from the moat.

A deposition system is provided capable of cleaning itself by removing a target material deposited on a surface of a collimator. The deposition system in accordance with the present disclosure includes a substrate process chamber. The deposition includes a substrate pedestal in the substrate process chamber, the substrate pedestal configured to support a substrate, a target enclosing the substrate process chamber, and a collimator having a plurality of hollow structures disposed between the target and the substrate, a vibration generating unit, and cleaning gas outlet.

A heat exchange system includes a shell having an interior with an inlet and an outlet wherein a first fluid circuit is defined from the inlet, through a heat exchange volume within the interior of the shell, to the outlet. A tubesheet is mounted within the shell dividing between the heat exchange volume and a plenum of a second fluid circuit within the interior of the shell. A set of tubes extends through the heat exchange volume, a respective interior passage of each tube being in fluid communication with the plenum through a respective opening though the tubesheet. The second fluid circuit includes the plenum and interior passages of the tubes. A spray nozzle is mounted in the plenum of the second fluid circuit with a spray outlet directed toward the tubesheet for cleaning the tubesheet with a submerged impingement jet issued from the spray nozzle.
