Industrial Boiler Economizer with Max. 20t/h Steam Production 1 Year Warranty and 5 Years Core Components Warranty
Boiler economizers are heat exchange devices with finned tubes that heat liquids (typically water) without exceeding the liquid's 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 models offer:
- Increased heat exchange area
- Reduced number of tubes required
- Expanded flue gas flow area to decrease flow speed and abrasion
H-finned tubes can be manufactured as double H-finned tubes for enhanced rigidity in long tube row applications. The spiral finned economizer features spiral fin tubes designed to overcome abrasion issues and extend service life.
The economizer reduces cooling costs by allowing compressor shutdown while maintaining adequate cooling capacity, resulting in significant energy savings.
