The beijing institute of environmental technology is the country's early research and promotion specialist in deep-processed machinery for agricultural products and green renewable energy products. The institute is based on china, developing a global market, building on its strong research and development capacity, focusing on the development, design, production and sale of new energy sources, high-tech machinery, new technologies, agricultural machinery and equipment, and new energy sources. It is dedicated to the development of new energy sources, the energy-efficient and environmentally friendly series of products, and to the development, design, production and sale of solar-related photo-sorpable materials, sheltering materials, temperature-conservation materials and reflective materials. Since its establishment in 2005, the establishment of branches in changsha (other regional branches are in the process of being established) and the establishment of three major production bases in kaguzhou, shenzhen and taian have resulted in a steady increase in research and development and production capacity, gradually becoming prominent brands in the energy conservation and solar industries for the environment and sustainable development of new energy sources. The beijing institute of environmental technology, with a strong scientific and technical team, has for many years been keenly looking at developments in new energy technologies, drawing on international best practices in energy conservation and environmental protection, and focusing on international co-industry science and technology in order to keep product development straight and up-to-date. With the strong technical support of the state, and with the support of the scientific community concerned, the solar energy "peace sun" has successfully developed a series of technical challenges to upgrade the traditional solar water heater, the "new products of the "peace sun" series, and has become a model for the application of new energy development technologies. It has rocked the industry in terms of its high technological content, its simple intellectual production process, its excellent use, and, once it has been introduced, it has generated consumer enthusiasm to buy it, sell it beyond the sea and be considered an "epoch-making product"。
