The GK1A series water chiller units are air-cooled monoblock systems, available in two configurations: with integrated storage tank (Version C) or for connection to an external buffer tank (Version V). Multiple modules—also with different cooling capacities—can be connected, even at different times.

These units use a non-flammable A1-class refrigerant blend with a GWP of 674, which contains PFAS. The GK1A series is suitable as a retrofit solution for replacing R407C and R134a refrigerants.

GK1A chillers are especially recommended for cooling applications in plastic and rubber processing machinery, die-casting machines, galvanic plants, ceramic presses, and many other industrial processes.
