Abstract
A coil cleansing assembly for automated cleaning of dirt and debris from within banks of heat exchanger coils is disclosed. The cleansing assembly is mounted above, below and between banks of such coils to enable focused jets of high velocity spray to impinge upon the surfaces of the coils and, thus, dislodge particles. It can be used with either individually finned tubes or plate fin coves of aluminum, galvanized steel or copper. Alternative embodiments for the cleansing spray assembly include a rotating arm system with spray ports mounted on a spray supply tube and a longitudinal track arrangement upon which a plurality of wand-type spray bars are mounted for reciprocating travel. Thus, the cleansing system of the present invention provides alternative arrangements for supplying jet-like sprays of water or other cleaning fluid to all regions of a bank or array of finned industrial coils in a multi-bank configuration, which flushes dust and debris from previously difficult to reach areas and ensure enhanced sanitation.
