Product Description
Hua Dong Heating System Quality Safety Boiler Economizer
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
- Spiral finned tube economizer
The H-finned tube economizer is a highly efficient heat exchanger consisting of H-finned tubes. Compared to bare tube economizers, H-finned tube models offer:
- Increased heat exchange area
- Reduced number of tubes required
- Expanded flue gas flow area to decrease flow speed and abrasion
Our H-finned tubes can be manufactured as double H-finned tubes with high rigidity for long tube row applications. The spiral finned economizer features a new design with spiral fin tubes to overcome abrasion issues and extend service life.
