Third DAHX Prototype


2019 – the final year of the UKRI project – resulted in the third scale prototype of the DAHX.

The design allowed for testing of two final fin-panel designs configured in an array. The design was aimed to be easy to configure for testing, and simple to manufacture.

The tests resulted in a fully validated optimal design, and it was proved to be scalable.

See the video below for an overview of the entire UKRI project.


  • Final tests proved product scalability.
  • Overall heat transfer coefficients comparable to standard fin-tube heat exchangers.
  • Third prototype design and production served as a pathfinder for a full sized version.
  • 2020 plan to scale up prototype and develop a full size version suited to Nando’s site requirements.
