1 CleanHUB - a totally new approach for wind turbine Hub and other components supply

2 System supply CleanHUB Oy is a joint-venture of several leading Finnish and international companies and experts in the wind power industry. They decided to join their forces to 1. deliver wind turbine hub as a system supply 2. provide new technologies for components supply 3. launch a revolutionary light and cost effective wind turbine hub and other big elements in nacelle

3 Vast experience in wind power All partners have experience in serving the major turbine manufacturers. By working together as CleanHUB Oy, we are able to offer you several benefits

4 CleanHUB technical competence consortium Casting, machining, pitch control, composite covers, electromechanics, assembly CleanHUB Oy has been founded to coordinate the production and marketing of new type of wind turbine products The first test hubs have been successfully made Next phases are test runs and certifications

5 The CleanHUB concept CleanHUB Oy delivers a complete hub to the wind farm construction site Preassembled, pretested, plug-and-play module including all the essential electric equipment Suitable for both direct drive and traditional mechanical solutions New casting technology and materials for key components New revolutionary machining system

6 Easiness & Reliability You will only have one quality supplier less management more profit and reliability Savings in life-time costs Less Operations & Maintenance costs, less downtime, Up to 50 % less weight, while the hub is lighter it means substantially lighter fundaments and tower Substantially faster and more accurate machining Substantially larger blade openings

7 Core technologies CleanHUB comes from: Meehanite Worldwide Brevini Power Transmission Ekin Muovi Ekin Composites Several other partners

8 Meehanite Advanced Casting Technology Faster solidification and cooling gives better material quality Cooling in a mould in less than 24 hours instead of 4 days Fawless casting gives more flexibility in designing No chunky graphite means thinner sections and inables use of stronger materials 3 MW hub weighs less than 10 tons The cost of hub casting is less than conventional Energy and material efficiency is remarkably better Investment in facilities is only about half Throughput of the foundry and machining is 5 times more than in a conventional foundry

9 CleanCAST Casting Technology Controlled cooling makes better material less defects, finer structure Better control gives opportunity to use stronger materials Faster through-put gives more capacity through less investment Lighter moulds require lighter cranes and building structure Moulds sized to shape of castings save 80 % sand and boxes

10 CleanCAST Hub Commercially proven new technology

11 Megaflex Machining

12 Benefits to Wind Turbine OEMs Most cost competitive EU supplier for Hubs Best available casting quality for heavy sections Fast flexible prototyping High capacity related to investment Environmentally friendly The new casting procedure allows up to 50 % larger blade openings - revolutionary possibilities to increase the whole production power of wind turbine Machining is very accurate and fast, only 5 hours instead the current 30 hours

13 The pitch system by Brevini Finland Oy Brevini Group is the biggest planetary gear manufacturer in the World Over 20 years experience in pitch/yaw gears One of the most modern factories opened in Italy 2011 (lean level 5) Strong investments in product development, education and training World s largest network in planetary gears with own subsidiaries

14 Composite hub covers by Ekin Muovi Ekin Composites many years experience in nacelle and hub covers, high level of own design and molding flexible production for small and large production hermetic and insulated, sandwich structure easy and smooth assembly and functionality, a.o. passageways, fasteners, lighting conductors the lightness of composite the freedom in design the strength also covers that conduct electricity

15 Ekin Muovi Oy 3 MW hub composite cover

16 CleanHUB market entry CleanHUB looks for partnerships with international turbine manufacturers to carry out the needed sertifications to create local flexible production strategy Production cooperation with the current CleanHUB foundries and/or present turbine manufacturer foundries Installing the Megaflex machining station with proper partners

17 All companies bring their expertise together, which means Synergy that benefits the client in a fundamental way. Casting, machining, pitch and control, electromechanics inside the hub and the hub cover - all made in a creative way. This results as logistical and economical savings and improves the functionality of wind turbine. Furthermore it extends its life-time. Instead of having several subcontractors, turbine manufacturer can communicate with one supplier, CleanHUB. CleanHUB takes the responsibility of the complete delivery
