Testing results

Our second Proof-of-Concept is performing extremely well; it’s fast, it’s stable and it cools perfectly to preset temperatures.

At lower temperatures we see a lot of condensation as expected; the cold plates are without any insulation at this phase, so […]

Second Proof-of-Concept

While most are enjoying their holidays, we’re making progress. Together with cooling partner Scala Scientific we’re finalizing the last bits and pieces of our second Proof-of-Concept. This one will be the first to cool the actual full cassettes down to -30°C. But obviously most tests will be performed around 20~25°C to avoid condensation.
