Abstract
A system capable of autonomous operation is disclosed for cleaning 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, a carriage for advancing the lance into the bundle, a mount movable relative to the carriage for holding the lance, and a sensor for detecting relative movement between the lance and the carriage, so as to detect when a reaction force acting on the lance upon encountering an obstruction in the tube bundle exceeds a predetermined limit.
