Abstract: Provided area cleaning apparatus and an associated method of using the disclosed apparatus wherein the apparatus utilizes one or more nozzles configured to provide a coherent stream of one or more cleaning fluids for removing accumulated fine particulate matter, sludge, from surfaces. The nozzles may be sized, arranged and configured to provide coherent streams that maintain the initial stream diameter for a substantial portion of the maximum dimension of the space being cleaned. The apparatus and method are expected to be particularly useful in the cleaning of heat exchangers incorporating a plurality of substantially vertical and narrowly spaced tubes by directing cleansing streams along a plurality of intertube spaces.

Abstract: The present invention relates to an improved ultrasonic cleaning system incorporating one or more improvements including, for example, permanently-attached flexible cables, waterproof bulkhead connectors provided on the transducers, submersible breakout assemblies, rigid cable guides and retainers, and at least one electronic switching unit whereby multiple ultrasonic transducers can be selectively driven by a single ultrasonic generator. The improved ultrasonic cleaning system may be configured with various transducer arrangements including, for example, elongated transducers provided on a carrying frame or structure and a more planar array configuration that may be assembled from a plurality of transducer subassemblies.
