Tisun: One Machine to Make Complete Solar Absorbers

Submitted by Baerbel Epp on June 8, 2012

 Pulsspeed Bender The new absorber production unit at Austrian collector and tank manufacturer Tisun has turned out to be a success: Since October 2011, the Pulsspeed Bender forms the meander pipe, while welding it simultaneously to the absorber plate - and then soldering it to the manifolds. The machine delivered by Austrian machinery supplier DTEC GmbH even pulls in the working material by itself. The system, which produces an absorber every three minutes, consists of different stations for cutting the absorber plate, drilling holes in the manifold pipes, soldering the pipe register and testing the pressure levels of the completed absorber. The heart of the absorber production line is the station, which in one single step, bends the pipe and welds it to the plate.

Submitted by Baerbel Epp on October 4, 2010

clinched Omega-shape absorber New absorber production process: The so-called Omega absorbers by Austrian company Estec Energiespartechnik Süd consist of coated aluminium plates, harp-type copper pipes and omega-form aluminium sheets. In order to join plate and sheet, the company uses an entirely automated clinching machine developed by Austrian machinery supplier RG Fertigungstechnik.

More Research Needed for New Storage Materials

Submitted by Baerbel Epp on November 17, 2008

If solar energy is to be the primary or only source of heat for houses in the future, there will arise a need for storing it more efficiently. Materials have to be found that are able to hold more energy than water, but with less volume and higher loss. Task 32 of the International Energy Agency's (IEA) Solar & Cooling programme was working on this issue. The scientists presented their results at the Eurosun 2008 in Lisbon, at the beginning of October.

Solar Heat Used Rarely in Industrial Processes

Submitted by Baerbel Epp on November 14, 2008

If solar heat likes to gain more importance in the future, it should not ignore the industrial sector. Task 33 of the International Energy Agency's (IEA) Solar Heating & Cooling programme performed an analysis of industrial energy needs and looked for the potential of solar heat within the sector. The Task’s scientists found a huge potential for energy from the sun. The industrial sector makes up about 28 % of total primary energy consumption in the European Union. A significant share of the heat used in industrial processes is used at low or medium temperatures.
