I'm not sure if it's the same manufacture, but similar rapids rides, off the top of my head, can be found at Wiener Prater, Skyline Park and Bayern Park.
I'm not at home now, so don't have access to pictures, but if you have a look for my Skyline Park trip report, I think there's a couple of pictures.
I keep meaning to sort out a Bayern Park report at some point as well. I know I have quite a few pictures of the rapids there, which seems to be the most similar to this one.
