Plate Fin Heat Exchanger

Plate-Fin Heat Exchangers tune-in to the level of efficiency you need

To make them more efficient, you typically must also make them larger and, therefore, they cost more. With our unmatched technology and expertise, our team has squeezed a lot of effectiveness into a smaller area with our patented Plate-Fin Heat Exchanger. This unique solution is a compact option for applications with tight volume or weight requirements since it can contain large heat recovery surface areas within small volumes.

Withstands Higher Pressures than the Competition

Our distinctive design features increased heat transfer surface area that conducts heat more efficiently than the competition. The fin area also adds to the structural integrity of the heat exchanger to allow the device to withstand higher pressures than comparable designs. The fin area, shape, and type can be adjusted to optimize heat transfer, flow rate, and pressure drop.

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+%
Application
Custom, fully packaged heat exchange system for SOFC stationary power unit
