Fin Shell Heat Exchanger

Patented design yields less energy consumption

The compact packaging of Heat Recovery Innovation’s Fin Shell Heat Exchanger delivers maximum heat transfer in minimum space. Our team carefully designs the exchanger with the exact shaped fin necessary to yield the results you’re looking for. These fins separate the plates to create flow channels that improve the internal and external tube heat transfer rates and provide superior cooling of large volumes at low pressure drops.

Driving even more compactness and performance

HRI’s Fin Shell heat exchanger is ideal for customers who require a reliable, high-quality heat exchanger that is low maintenance, long-lasting, and more compact than other available designs. Even with an enlarged surface on the shell side, customers achieve increased heat transfer rates across the board with this highly efficient and space-saving solution.

PLATE-FIN HEAT EXCHANGER APPLICATIONS

Solid Oxide Fuel Cell

OverviewResults

Solid Oxide Fuel Cells (SOFC) are electrochemical systems that produce electricity from oxidizing fuel at high temperature rather than combustion.

In contrast, common combustion-based generation is only able to achieve 30-40% fuel efficiency

SOFCs provide high power efficiency, fuel flexibility, very low emissions, and competitive costs

The HRI heat exchangers help the system achieve exceptional fuel efficiency (greater than 60%) by recycling process generated heat
Generation TypeElectrical Efficiency
Reciprocating Engine35-40%
Gas Turbine30-40%
Nuclear Power33-37%
Coal Fired Plant33%
Solid Oxide Fuel Cell60+%
