1 Technical Solutions for Renewable Energy intelligent engineering safe clean long-lasting Senior Berghöfer CSP Technology Concentrated Solar Power Your partner with more than 25 years of experience for flexible solutions in Solar Thermal Power Plants R & D Supply Service

2 2 / 3 SENIOR GROUP WORLDWIDE Senior plc. is an international group of companies with production sites in 11 countries around the world, split in two divisions (Aerospace and Flexonics) with employees, guaranteeing direct availability and local presence. Eliminating bottlenecks: With our global delivery network Our organisation a financially strong and world wide operating group designs, develops and manufactures high technology components and systems for sensitive environments and most demanding applications in many industrial areas. Senior Berghöfer GmbH, a member of the Senior Flexonics Division, with its 300 employees at 3 production sites benefits from more than 100 years of experience in the development and production of flexible metallic elements with the highest material and quality standard. We develop, design and manufacture flexible components and connection systems as OEM products for various industries with the focus on Renewable Energy, especially CSP, wind, water and other specialized applications. Our products are traditionally applied where highest safety requirements are to be met with regard to extreme temperatures, pressures and media or where emission limits within tight tolerance have to be observed.

3 4 / 5 Hose braiding Thermogram of Rotationflex 2 nd Generation YOUR BENEFITS We are your development partner, therefore we encourage you to consult us at an early stage. Test Rig 1:1 scale In accordance with your profile of demands and specifications, we produce initial prototypes for internal or field testing under real conditions, based on linear / non-linear finite element simulations and analytical calculations. In-house: Calculation, simulation, design, prototype and tool manufacture, 1:1 testing. Absorber bellows production Appropriate tooling, machinery, models as well as our own test rigs for initial and long-term test series are available. We can measure temperatures, pressures, displacements, flow rates, strains and more very precisely. Results of the analysis of weak points are incorporated in any optimization of the component which might be necessary. We guarantee outstanding performance. A distinguished quality and environmental management system is a natural precondition for our work. We dispose of the following certifications: Quality Management: DIN EN ISO 9001:2000, ISO/TS 16949:2002 Environmental Management: DIN EN ISO 14001:2005 and EMAS DE Hydraulic forming Is the most important forming method which allows us to create any convolution geometry in a very economical way. Materials: All standard stainless steels as well as special alloys are available and 100 % recyclable Automatic welding assembly

4 OUR PRODUCT PORTFOLIO 6 / 7 Rotationflex 1 st Generation Size 2 Medium: Thermo-oil and molten salt Operating Conditions: to be defined In 1986, after two years of Today these power plants are development, we started to still supplying sustainable supply key components to the clean energy to thousands of first commercial solar power households with the reliable plants in the world, the SEGS contribution of our flexible I-IX plants in California/USA. elements. Extensionflex Size 2, 2 ½ and 3 Sophisticated hose system connecting to the feed line, compensating the thermal extension of the collector absorber tube. Large axial extension > 4000 mm High pressure and tempera- ture resistance No break-away torque Long life-time Rotationflex 2 nd Generation Size 2 ½ Medium: Thermo-oil, gas and steam Operating Conditions: to be defined Innovative absorber tube bellows HCE Bellows Special metal bellows to compensate thermal expan- sion of different materials, securing the correct function of the heat collection element (HCE). Individual design High flexibility High efficiency Long physical life The development of the optimized Rotationflex design started in 2003 in close co- operation with the VDI / VDE and the financial support from the Federal Ministry for the Environment, Nature Conser- vation and Nuclear Safety (BMU). Rotationflex Next Generation Other designs are under development to further improve efficiency. Validation / Verification: 2006 mid 2008 Marketability: End of 2008 Prevention of forces into the trough structure of the HCE Easy control of the break-away torque via the driving device Long life-time Different size High pressure resistance High temperature resistance Suitability for alternative media Expansion joint system for feed line Triple hinged expansion joint system FL Expansion Joints Senior Berghöfer GmbH individually designs metal expansion joint systems using multi-ply design for the compensation of thermal expansion in the feed lines (FL). Significant cost savings compared to existing systems (tube material, construction work, space and medium) Elimination of reaction forces Long cycle-life Senior Berghöfer GmbH your system developer and supplier accompanies every project from start to completion, including support in the field. WE LIKE TO MOVE WITH THE SUN
