Publication number: 20150013725Abstract: A pair of parallel metal lances is driven by a transversal drive into and out of heat exchanger tubes. The lances are supported by a plurality of spaced apart, retractable door supports so that the transversal drive mechanism can approach the tube sheet of the heat exchanger tubes as closely as possible. A pair of rotational drive motors rotates the lances at a user controllable speed. As the lances are moved into the tubes, the interlocked support doors retract one at a time, sequentially. Similarly, as the lances are withdrawn from the tubes, the support doors close one at a time in an interlocked fashion.Type: ApplicationFiled: September 30, 2014Publication date: January 15, 2015Applicant: AQUAJET LTD.Inventors: Christian Geppert, Stefan Scroth

Patent number: 8122898Abstract: A rotating and telescoping cleaning system improves high pressure water cleaning of the inner surfaces of vessels or tanks. Vessels can be vertically divided with dividing plates with centered through-holes. Synchronized and controlled transverse and rotary movements of water jets result in a controlled spiral or helical cleaning track along the vessel walls. The water jets are directed at a pre-adjusted distance from the vessel wall and the travel speed of the water nozzle jets is exactly controlled allowing the removal of very hard deposits. One pass with the tool carrier with operating water jets along the length axis of the vessel results in a thoroughly cleaned vessel wall. The tool unfolds and folds inside of the vessel powered by the flow of the high pressure cleaning water.Type: GrantFiled: June 4, 2009Date of Patent: February 28, 2012Assignee: Aquajet Ltd.Inventors: Christian Geppert, Stefan Schroth
