Technology Description:

CompRex aims to transform heat exchange technology for high temperature (>800°C or 1472°F) and high pressure (80 bar or 1160 psi) applications through the use of advanced metal and ceramic composite material, development of a new simplified manufacturing approach, and optimization of heat exchanger design based on the new material and manufacturing process. This solution could not only satisfy the performance requirements of next generation power cycles but also significantly lower costs of production and scale-up by as much as 40% compared with existing state-of-the-art heat exchangers. The same manufacturing approach can be applied to different materials to produce various devices such as pumps and reactors. This versatility could expand the technology’s significant performance and cost advantages and disruptive potential in a broad array of applications, including transportation, aerospace, and oil/gas/petrochemicals.

Potential Impact:

HITEMMP projects will enable a revolutionary new class of heat exchangers and innovative approaches to advanced manufacturing with applications for a wide range of commercial and industrial energy producers and consumers.


High performance, efficient heat exchangers would increase industrial productivity, supporting domestic industries. The developed manufacturing techniques for high temperature materials could strengthen U.S. leadership in advanced manufacturing.


More efficient electricity generation and industrial processes could significantly reduce emissions by enabling more efficient operations.


HITEMMP technologies could enable more cost-effective, efficient, and compact modular power generation systems for multiple applications.
