Product Introduction
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.
The H-finned tube economizer is a highly efficient heat exchanger consisting of H-finned tubes. Compared with bare tube economizers, H-finned tube economizers can significantly enlarge the heat exchange area while reducing the number of tubes required. This design also increases flue gas flow area to reduce flow speed and minimize 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 utilizes spiral fin tubes to overcome serious abrasion issues and extend service life.
Function & Benefits
The primary function of the economizer is to "economize" or save on cooling costs. By enabling compressor shutdown while maintaining adequate cooling capacity, significant energy savings can be achieved.
