High Pressure Boiler Economizer Heat Exchanger with 3 Years Warranty and 1-20 Ton Capacity
Boiler economizers are heat exchange devices with finned tubes that heat liquids (typically water) to temperatures below their 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, it offers:
- Expanded heat exchange area
- Reduced number of required tubes
- Increased flue gas flow area
- Reduced flue gas flow speed and abrasion
Our H-finned tubes can be manufactured as double H-finned tubes with high rigidity to accommodate long tube rows. The spiral finned economizer is our innovative design featuring spiral fin tubes to overcome abrasion issues and extend service life.
