The GM1A series water chiller units are air-cooled monoblock systems, available with an internal storage tank (Version C) or for external buffer storage (Version V). Multiple modules, including those with different capacities, can be connected even at different times. These units use pure R32 gas, a flammable refrigerant classified as A2L, with a GWP of 675. They do not contain PFAS and are not intended for retrofit applications.

These chillers are particularly suitable for cooling plastic and rubber processing machines, die-casting machines, electroplating plants, ceramic presses, and numerous other industrial processes.
