The predecessor of Zhejiang Liju Thermal Energy Equipment Co., Ltd. was Hangzhou Liju Water Heating Machinery Co., Ltd., which was founded in 1997. The company is headquartered in Huzhou, Zhejiang Province. It currently has more than 700 employees, a total production base area of ​​more than 320 mu, and an annual output of 10,000 tons of gas boilers. It has obtained more than 80 national patents, including 10 Chinese invention patents and 2 US invention patents. After the establishment of the company, it has focused on the research and development and production of vacuum hot water boilers. It has long adhered to the business philosophy of "science and technology are the primary productivity and professional achievement" and insisted on high investment in R&D. It has now become a leading gas boiler with domestic technical strength and scale. One of the production enterprises.

Liju's core technology - WCB water-cooled premixed ultra-low nitrogen combustion technology, developed by Liju, has completely independent intellectual property rights, and won the "First Boiler Science and Technology Award First Prize". This technical product realizes the safe and stable operation of a single module 35MW fully premixed gas boiler for the first time, breaking the foreign monopoly. WCB water-cooled premix combustion technology can efficiently inhibit the synthesis of nitrogen oxides (NOx), achieve ultra-low nitrogen emissions (NOx<30mg/m3), and meet the most stringent ultra-low nitrogen emission standards in my country. The company's main products include: ultra-low nitrogen gas hot water boiler, ultra-low nitrogen gas steam boiler, ultra-low nitrogen gas heat pipe steam engine (steam boiler without supervision), electrode phase change hot water and steam boiler.

The company has obtained a Class A boiler manufacturing license and a pressure vessel production license. It has been rated as a national high-tech enterprise, a "Zhejiang Province Hidden Champion" enterprise, and a "specialized, specialized, and new little giant" enterprise of the Ministry of Industry and Information Technology.
