Cascade refrigeration systems with water or air cooled condensers.

MultiStage is an integrated cascade refrigeration system, with water or air condensation, designed to provide high efficiency cooling conditions to processes with a high temperature drop. It consists of refrigeration modules (Modular Chiller) arranged in series and fully exploits this large temperature differential, allowing the stages to operate with the highest evaporation temperatures and, therefore, with the maximum refrigeration performance (COP/EER). MultiStage can be synchronized digitally with the processing line and automatically managed by it.
