GRW series water coolers are compact devices condensed in water. They are produced in two different versions: with a built-in tank (C) or an external tank (V). GRWC series coolers are available in a modular expandable version (C) enabling connection to other units with similar or different cooling capacity in the future. The GRW series is specially designed for mold cooling of plastic processing machines; they can also be used in other similar industrial processes.
