Cooling Samples to -40 °C
A university research team utilized TECA’s AHP-1200C31 Cascaded Cold Plate to build a calorimeter for a research paper that was recently published. The researchers aimed to determine the thermal properties of their specimen as part of a study on cement and concrete durability.
Originally the customer used only the AHP-1200CAS base cold plate and was able to reach -15 °C. When he determined that colder temperatures were needed, he added the CCP-31 cascade attachment to reach -40 °C. With a cascade system each cascade stage acts as a heat sink for the stage above it. This allows the top stage to reach colder temperatures.
TECA offers two and three stage cascade systems for reaching temperatures as low as -60 °C (LHP-1200C31).
