High Efficiency Boiler Economizer with Max. 20t/h Steam Production and 5 Years Warranty for Core Components

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:

• Expanded heat exchange area
• Reduced number of tubes required
• Increased flue gas flow area
• Reduced flue gas flow speed and abrasion

H-finned tubes can be manufactured as double H-finned tubes for enhanced rigidity in long tube rows. The spiral finned economizer features a new design with spiral fin tubes to overcome abrasion issues and extend service life.

The economizer's primary function is to reduce cooling costs by allowing compressor shutdown while maintaining adequate cooling capacity, resulting in significant energy savings.
