Problems, problem...unit won`t be at CeBIT, I am really sorry...

I stage is strong, holds load very well, -55*C rock stable !

II stage...well, I expected a lot more...sometimes it hits -115*C (!), sometimes it`s not able to hit -30...usually it`s around -50*C at the plate Hx exit...

From what I see, to flood Hx I need a hugeeeee amount of ethylene, but then , when HX is flooded (-100 at exit), at III stage I`ve got so ing low pressure, that R14 won`t condense ! Static 15bar, when working with 2 stage on, 3bar high side pressure !! happens...
