Company Profile
China-Swiss Group focuses on the R&D, manufacturing, promotion and application of clean energy and new energy technologies in China. Leveraging China's abundant human resources, manufacturing capacity and improved industrial chain, the group has completed the industrial layout of environmental protection boilers centered on the Chinese mainland market and radiating globally. It has established branch offices and agencies in provinces and cities across the country, responsible for product sales and after-sales services.
Amid the global energy scarcity, China-Swiss Group joined hands with the Royal Institute of Technology in February 2010 to establish "Nanjing China-Swiss Boiler Co., Ltd. ". Relying on international talent and technological advantages, the company timely introduced Europe's most advanced energy-saving and environmental protection technologies, and launched the "China-Swiss" brand of oil-fired, gas-fired and electric boilers using clean energy as fuel.
In July 2010, "China-Swiss Boiler" was awarded the title of "Most Environmentally Responsible Enterprise" at the 4th Shandong Green Expo.
In November 2011, the group further expanded and established "Yangzhou China-Swiss Boiler Co., Ltd. ". In 2012, it launched an OEM cooperation with a boiler manufacturing company in Jilin Province, leveraging the manufacturing resource advantages of Northeast China's old industrial base for resource complementarity and exploring the northern market.
In July 2015, Yangzhou China-Swiss Boiler Co., Ltd. Obtained the Class B Boiler Manufacturing License and launched the high-efficiency condensing waste heat recovery gas-fired steam boiler, with a thermal efficiency of 96~103%. The product fully complies with the global development trend of low-nitrogen economic technology advocated at the Copenhagen Climate Conference.
In January 2025, Yangzhou China-Swiss Boiler Co., Ltd. Obtained the Class A Boiler Manufacturing License and launched the fully premixed vacuum/phase change hot water unit, with a thermal efficiency of 96%~108% and nitrogen oxide emissions below 20mg/m³.
In addition, the company has independently developed a series of products, including condensing indirect heating hot water units (boilers), condensing vacuum hot water units (boilers), condensing atmospheric pressure hot water units (boilers), flue gas waste heat recovery organic heat carrier (heat transfer oil) boilers, biogas boilers, environmentally friendly coal-fired boilers and biomass boilers.
Shouldering the responsibility of energy conservation and emission reduction, China-Swiss Boiler maintains close cooperation with many large enterprises at home and abroad. Its products are widely used in industrial processes such as textile, printing and dyeing, papermaking, food, rubber, plastic, chemical, pharmaceutical, steel and metallurgy for steam and hot water needs. They also provide heating, bathing, air conditioning and domestic hot water for enterprises, government agencies, hotels, schools, catering and service industries.
The company boasts Europe's advanced scientific and technological management system, sophisticated process equipment and a high-quality workforce. Adhering to the business philosophy of "Technology, Environmental Protection, Innovation", taking technology as the core and market demand as the orientation, building a leading brand of low-nitrogen boilers in China has become the inexhaustible motivation of China-Swiss people!
