PCM SP-line
PCM with High DensityRubitherm SP products are PCMs (phase change materials / latent storage media) based on salt water mixtures and additives. Their phase change from solid into liquid and vice versa is used in order to release and store high heat quantities, respectively. Compared to the RT materials their melting temperature is shifted compared to their freezing temperature, however, it amounts only to a temperature difference of 1 K, which is very small. These materials have been created directly at Rubitherm. More information are available here.
Another commonly described problem of inorganic PCM materials is the cycling stability. In order to ensure this stability, we cycle the SP materials in our laboratory, some of them up to10.000 cycles. In this way, we can rule out aging effects.
The SP materials that are produced at Rubitherm are favourably filled into macro-encapsulations and are used for active and passive cooling and heating systems, e.g. for air-conditioning, inroof and wall elements. There is a possibility to fill these materials into our compact storage modules or other macroencapsulations.
