The GQ1A 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 a flammable refrigerant gas blend classified as A2L, with a GWP of 146, containing PFAS. The GQ1A series is suitable as a retrofit solution to replace R407C and R454C refrigerants.

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