    Some PCM Products

  • CieloSOL PCM21/300 CieloSOL PCM21/300

    PCMs are materials based on latent heat (melting or freezing) which store the excess of energy around them and in time of need.

  • CieloSOL PCM24/310 CieloSOL PCM24/310

    In doing so, they quite sharply force the environment to be at a certain temperature called “Phase Change temperature”.

  • CieloSOL PCM58/421 CieloSOL PCM58/421

    The materials will resist the deviation of the temperature.The Phase Change temperature of CieloSol PCM28/315 is of 28 Celsius degrees.

Cielo Este was established in early 2011 in Andalusia Technology Park to concentrate and reorganize experiences and activities in four areas of Electrical, Power Electronics, Phase Change Materials and Solar Power products and solutions.

  • Storing collected energy by solar panels in buildings

    One of the applications of Phase Change Materials is collecting solar energy from buildings with the ability to store such energy through solar collectors. By using Phase Change Materials in these systems, a high volume of solar energy can be stored during daytime and used for heating and as warm water supply at night. Phase Change Material in such systems are normally positioned layer by layer or spherically in thin chambers and then the heat transfer fluid is passed on without contact through chambers with the material.

  • For Phase Change Materials, A New Use in Digital Displays

    By simultaneously exploiting a material’s electronic, optical, and structural properties, researchers in the U.K. have taken a first step toward developing a new type of electronic display technology.

  • Scientists Report Smallest Phase Change Material to Date
