Abstract:
A system to produce a high pressure stream deionized water, for cleaning vehicle bodies, comprising, in combination:a) first and second deionization beds within first and second vessels, b) a first conduit or conduits to conduct non-deionized water at a relatively low pressure or pressures to pass through the first bed to deionize the water, c) a primary sensor to measure the deionization level of water that has passed through the first bed, d) a second conduit or conduits to conduct water from the first bed to the second bed to further deionize the water, if required, e) a pump to receive water that has passed through the second bed, or through the first and second beds, and to pressurize said received water to a level of at least about 1,200 PSI, f) and a nozzle connected to the pump and operable to controllably dispense a high pressure stream of deionized water for highly effective cleaning of said bodies, g) and said primary sensor including means for sensing the level of dissolved solids in the water flow from one of the beds, and to conduct water flow to the other of said beds in response to said sensed level exceeding a predetermined threshold.
