The performance and durability flagship: fastest cooling, toughest build, best warranty. Overkill and very pricey unless you want commercial-grade cooling at home.
The CoreChill is BlueCube's residential model built around a 1 HP commercial chiller with Japanese compressors that drops water 11-13F per hour to reach 37F faster than most rivals and holds it 24/7. The 316-grade marine stainless body is handcrafted in Oregon, with automatic ozone and 20-micron filtration and a 3-year full plus 15-year frame warranty.
