Water condense refrigerant (R507) in this system .

what copper pipes can you connect to this plate hx?

i have also two pieces of the same 20´s phx but they have only 4 of 12,5mm inlets to connect 12mm copper pipes.

are you using 15 or 16mm pipes for the water cycle?

Yes, I have 15mm OD cooper pipes in liquid loop . Strange Plate HXes You have bought :-O . On the other hand that's good because to cascade we don't need such big "reduction" of size.

Very cool build, Pieter! With this sort of subambient condensing, you may as well have used R-410A without any problems!

I know that, I've tried R410a but haven't notticed lower temps compared too R507 . That gas which is now in unit is even blend of some 410a with more 507.

The water loop replaces the condenser and fan like on a typical single stage.
