Testing phase change materials and performing long-term thermal cycling for newly developed materials by customers to measure the thermal performance and stability of the phase change.
The measured thermal properties are such as enthalpy, temperature profile, melting and solidification temperatures, specific heat capacity, supercooling, and stability/degradation with time and while cycling.

The three-layer calorimeter is a measurement setup for PCMs recognized by the RAL PCM Quality Association. It provides a real and precise measurement with an average cooling/heating rate of approximately 0.03 K/min applied to the test samples which weigh 60 – 100g each. The large sample quantity reduces the impact of potential weighing tolerance deviations. This allows a correct measurement for example of salt hydrate PCMs because the sample contains sufficient quantities of all required components, nucleating agents, and crystals to be representative of the PCM as a whole.

Unique possibility to measure PCM Enthalpy in larger sample sizes, especially salt hydrates.
