My 1st cascade R22/CO2

[Big SturL]

15 bar (!) static? I might have missed out on a vital point with cascades, but will the pressure on second stage actually drop while running?

It will because gas will be cooled by I stage.

For example, my 3 stager. Second stage is charged with 17bar of R1150 (no expansion tanks). why that much ? To hold load

While running, under load, I`ve got 11bar discharge on that stage :-)
