ABSTRACT:
This invention relates to equipment and a method for providing superior power washing at relatively low pressures. The equipment uses a unique mixing chamber wherein a pressurized water stream is mixed with a pressurized additive stream. For example, the additive stream enters the mixing chamber at a pressure at least that of the carrier, or water, stream. There is no need to operate the carrier liquid stream at substantially higher pressures than the desired delivery pressure.
