When I worked in the ice industry we had a lot of 5h120's in turbo ice makers. We had two 80 ton machines inside another one on the roof along with some 40 something ton something turbos. I really miss those things. I remember them rebuilding them in house a couple of times. They were not very successful of course they also told me you remove moisture from systems with diapers. Those 5h turbos could really rumble and make some ice! Dying breed.
