Boiler economizers are heat exchange devices with finned tubes that heat liquids, typically water, up to but not exceeding the boiling point. We manufacture three types of boiler economizers: bare tube economizer, H finned tube economizer, and spiral finned tube economizer.
H-finned tube economizer is a high-efficiency heat exchanger consisting of H-finned tubes. Compared with bare tube economizers, H-finned tube economizers enlarge the heat exchange area while reducing the number of tubes required. This design increases flue gas flow area, reducing flow speed and abrasion.
H-finned tubes can be manufactured as double H finned tubes with high rigidity to accommodate long tube rows. The spiral finned economizer is a newly designed heat transfer equipment that overcomes serious abrasion and extends service life.
The economizer functions to "economize" or save on cooling costs by enabling compressor shutdown while maintaining adequate cooling, resulting in significant energy savings.
