Low Temperature Compact
Heat Exchanger

HiETA have developed and deployed core IP in two key areas that allow us to produce Low Temperature (up to ~250°C) Heat Exchangers that are a step-change improvement on the current industry standards.

High-value design:  Our team of skilled thermodynamic engineers have developed heat transfer surfaces capable of delivering significantly increased heat transfer coefficients with minimal pressure drop penalties. The freedoms of the process also allow our designers to employ novel manifold optimisation techniques to ensure flow distribution to the core is such that the performance of the unit is maximised. These can be combined in heat exchange package shapes that are best suited to the application, be it cuboid, annular or something more freeform and flexible.

>10,000 cycles on highest life aluminium heat exchangers.


  • AlSi10Mg
  • TiAl64V
  • SS316 L

Reliability: Performance is nothing without longevity and reliability though, and as such HiETA have found customers and products to work with to test, understand and validate our technology. We are very proud to have been producing and operating low-temperature heat exchangers in the field for over 3 years now, with the highest life units having in excess of 100,000 cycles (thermal loading, vibration, shock, pressure pulsation). This gives us great confidence in our designs and technology.

Applications: The technology is well suited to a range of air and fluid-based lower temperature applications, including (but not limited to) oil coolers, intercoolers, charge air coolers, fuel oil heat exchangers and electronics cooling.
