Our economizers are manufactured using high-frequency welding technology with steel strips automatically spiral-welded to the tube exterior. This construction method provides larger heat transfer area within the same diameter and length parameters. All products comply with ASME standards and are backed by comprehensive quality certifications including ISO9001, EN12952, and Grade A manufacturing standards.
Designed for coal-fired steam boilers, coal-fired hot water boilers, and CFBB bed boilers in power plants and industrial facilities. Customized orders are available to meet specific project requirements.
