Abstract
A heat exchanger cleaning system is disclosed which is capable of determining the position of a lance within a tube bundle of a heat exchanger core. The system comprises a lance for directing a jet of fluid into spaces between the tubes of the bundle, an arm mounted alongside the lance and movable relative thereto, an abutment mounted to an end of the arm to sense an outer surface of the heat exchanger core, and a transducer for measuring the position of the lance relative to the arm to determine the extent of travel of the tip of the lance beyond the front face of the tube bundle.
