Hummer devotes herself on doing the research, development, production, sales and service on medium and small sized wind turbines, as well as providing solutions for small wind farms. Her manufacturing base, covering an area of 7.5 Acres, is located in China Anhui Lujiang economic and technical development zone. With about 200 workers among whom 40 R&D personnel, more than 70 sets production equipments and 30sets detecting system, it gains a 3000sets monthly production capacity and 20,000 sets annual production capacity. Hummer specializes in researching, developing, producing and promoting of small-sized wind generator system, and also provides solutions for setting up small-scaled wind farm. After nearly 30 years efforts, our company has developed independent intellectual property rights of "Hummer" wind generator and control system. “Hummer” has produced both off gird and grid tied wind power generating systems from 400W to 50KW and in 18 ranges of specifications. Light, small, fast, stable; small sized with high efficiency. Hummer wind turbines have passed European CE certificates; generator part has passed American UL certificate. Special Features: Most advanced technology supports “Hummer” wind generators become Famous in the world: 1. SCF generator technology takes advantage of special structure and materials to take the generator operate in critical state. 2. The SCF generator has been setup the position before the blade inside the Nose Cone it’s most advanced technology comparing the traditional one. 3. SCF Supercritical Generator Technology (this technology won gold model of the 37th annual world invention exposition in Brussels eureka) as the core; 4. With 7 patents and independent intellectual property rights. we have researched and developed medium and small-sized wind turbines; 5. SIEMENS PLC controller with rigorous system. Good integration and strong specialization, as features with small volume, standard design, high reliability as well as strong network communication ability, it will realize the complex control for one or more associations. 6. SKF (Svenska Kullager Fabriken) bearing has been adopted which is produced by the largest bearing manufacture in the world. With the perfect internal geometric structure, rough surface. Stable inner and outer ring. Its advantages are more obvious
