A cascade unit combines both a condenser and an evaporator (flooded or DX). Vahterus PSHE are ideal for cascade operations, based on their high thermal efficiency, a minimum temperature difference between the evaporative and condensing media, and low running costs. Using Vahterus fully welded construction ensures there is no leakage or cross-contamination. The unit is easy to install as well as to insulate. In refrigeration cascade heat exchangers are used to transfer heat between two refrigerants. They are used especially with CO2.
In process industries the cascades can be used as highly efficient steam transformers where there is black steam condensing in plate pack and clean steam generated in shell.
