Oil/Gas Fired Vacuum Hot Water Boiler

The AIX CWNS Series Oil/Gas Fired Hot Water Boiler, manufactured by AIX Boiler, a Chinese A-grade producer since 1976, is a horizontal, fire-tube boiler using vacuum phase-change technology to produce hot water for industrial and commercial applications. This technology ensures high thermal efficiency (up to 96%) by leveraging phase-change heat transfer, reducing fuel consumption. The boiler’s compact, fully automatic design simplifies installation and operation, with low NOx emissions meeting stringent environmental standards. Equipped with advanced burners and safety features, it’s ideal for industries like hospitality, textiles, and food processing. AIX CWNS boilers offer durability, low maintenance, and eco-friendly performance, making them a reliable heating solution.
