[Emz80s]

I need any material or isometric for Cryogenic heat exchanger 4 passes that has one pass is cooled and the others are heated

And is there any difference between this type and traditional heat exchanger

Normally for cryogenic service with multiple services, Brazed Aluminium Plate-Fin Heat Exchangers are used. Refer to

https://www.alpema.org/

for more details Use of this type of heat exchangers are very common in the air separation industry. On LNG service, Aluminimum may not be preferred considering the contaminants/composition and for these service Coil-wound, heat exchangers are normally used. These exchangers can have the advantage of using a wide range of materials based on the service.
