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...
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...
Figure of a bending machine for serpentine absorbers: the bending head is situated in the middle of a horizontal table – in some cases supported by a sliding block to obtain the best bending angle.
Great response: The 5th China International Solar Energy Autumn Trade Fair in Changzhou, Jiangsu province, sparked the interest of a high number of exhibitors. Photo: Joseph Huang
Patented feature of a new fleece insulation made of polyester fibre: Bending it in the other direction will easily show you the tapered form of the insulation.
What counts is the quality of the collar: Dagan´s punching machines possess a special die, which works together with the internal punch to optimize the form of the collar.

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...
- 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...
