Stainless Steel Spiral Fin Tube for Energy Conservation in New Condition

Boiler economizers are advanced heat exchange devices featuring finned tubes that efficiently heat liquids, typically water, up to temperatures approaching but not exceeding the boiling point. We specialize in manufacturing three distinct types of boiler economizers: bare tube economizers, H-finned tube economizers, and spiral finned tube economizers.

The H-finned tube economizer represents a high-efficiency heat exchange solution composed of specialized H-finned tubes. Compared to conventional bare tube economizers, this advanced design significantly expands the heat exchange surface area while reducing the total number of tubes required. This configuration also increases flue gas flow area, effectively reducing flow velocity and minimizing abrasion.

H-finned tubes can be manufactured as double H-finned tubes, providing exceptional structural rigidity ideal for extended tube row applications. The spiral finned economizer incorporates a newly engineered heat transfer design utilizing spiral fin tubes to overcome issues of severe abrasion and extend service life.

As the name implies, economizers are designed to "economize" or optimize energy consumption. By efficiently recovering waste heat, these systems enable compressor shutdowns while maintaining adequate cooling capacity, resulting in substantial energy savings and reduced operational costs.
