A jet clean nozzle having multiple spray openings which increase the scan density of pressurized water sprayed against the surface of a semiconductor wafer. In some aspects of the invention, multiple master tags and signal control elements manage the communication of unique signals indicating and managing inventory status and consumption activity. Optional sidebars extending from the module sides provide stability when the module is hanging. The vortex generator is constructed, i. The closure unit includes a mechanical drive which mechanically couples the closure element to a rotational movement of the receptacle which moves the closure element to the open position or closed position.
