Lage capacity(1,090 Mcal/h) ice slurry generator was developed and adopted as main equipment of hospital cooling system. This ice generator is the largest scraper type ice slurry generator in the world. Generator use centrfugal compressor and all components are in one skid. We expect It could solve the problems of hampering extension or ice slurry system and ice slurry generator. We have tested the ice generator on capacity, efficience, and credibility.
