CRISTOPIA STL (Storage of Latent heat) is a type of technology which utilizes nodules to store the cooling energy which has been produced by water chillers. Cooling demand is lower at night so this is the optimum time to store the energy. It is redelivered during the day when the cooling capacity is needed the most. The lower temperatures at night, when the energy is stored, enable the chillers to function more efficiently. Smaller units are used as the demand and distribution of the chillers is better balanced between day and night. The integrated Cristo'Control2 is a unique control and supervision system.
