Cascade heat exchangers are used to transfer heat between two refrigerants.
They are used especially with CO2. A cascade unit combines both condenser and evaporator (flooded or DX).
The Plate & Shell Heat Exchanger is ideal for cascade operations with high thermal efficiency and can provide minimum temperature difference between the evaporative and condensing media with low running costs.
The fully welded construction ensures there is no leakage or cross-contamination.
