1.Company introduce:
Qingdao Renergy Equipment Co., Ltd. is a professional small and medium wind turbine.Our factory cover an area of 2,000 square meters and has the most advanced and self-developed generator test platform, wind rotor balance system, variable pitch test platform, fatigue strength testing lab and other various wind turbine specialized detection equipment.
With over ten years' experience in wind turbine business, we have developed variable pitch wind turbine, Aero dynamic brake system (ABS system), and intelligent control system:
2008 --- The first variable pitch wind turbine in China, was designed and manufactured by RENERGY. RENERGY started to be known as the safest wind turbine in China.
2010 --- ABS system was designed; RENERGY improved the safety of wind turbine.
2012 --- Intelligent control variable pitch wind turbine was designed. Small wind turbine started to have a smart brain.
