What's your feedback, based in the experience of working with cascade refrigerant plants with R717 (high temperature) / R744 (low temperature), in using semi-welded plate R744 condenser of ALFA LAVAL M10 and MK15 or with another brands?

Forget M10
Use AlfaRex, Plate and Shell or Shell and Tube
Hello !
Use the Brand "vahterus" !
They have shell and plates heat exchangers for CO2 applicaions : pump / flood etc ... with very high design presure if you Want. In france, we must design a heat exhanger at 50 bars if we use hot gaz for defrosting and the test presure must be at 100 bars. Just "vatherus" can do that. and the cost is very below a Alfa laval model.
Best regards
I can give to you my contact for "Vatherus" if you whant !!
