Since the end of March, the absorber production industry in Europe has had a fairly different look: As of 28 March 2014, Alanod has been the new owner of Bluetec. Both companies are well-known specialists for highly selective absorber coatings for the solar thermal collector industry. Besides providing coated aluminium and copper sheets, they also manufacture and supply highly reflective aluminium for the lighting industry.
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. Photo: DTEC/Tisun
Austrian collector manufacturer Tisun GmbH started operating a new type of absorber production machine at the beginning of November 2011. Developed and delivered by Austrian machine supplier DTEC GmbH, the special feature of the machine is its ability to bend and laser-weld parts in a single production step. “We have patented the three-dimensional head which bends, forms and welds the piping to the absorber plate,” explains DTEC’s Managing Director, Michael Dietl.
