Hangzhou Hangning Thermal Energy Technology Co., Ltd. is rooted in a deep and extensive foundation of heat pump technology. Since 2009, the company has embarked on a journey of technological breakthroughs and market expansion, establishing itself as one of China's earliest enterprises dedicated to the R&D and application of compressors specifically designed for heat pump water heaters. In August 2009, in collaboration with Shanghai Hitachi, the company successfully developed China's first heat pump water heater unit utilizing a dedicated heat pump compressor—making it the first manufacturer in China to adopt such specialized components. That same year, the company signed a comprehensive strategic partnership agreement with AFIS of South Korea, simultaneously laying the groundwork for its presence in both domestic and international markets. Between 2009 and 2010, the company's residential and light commercial products rapidly obtained national CCC certification, EU CE certification, and certification from the Korea Refrigeration and Air Conditioning Industry Association.
