The GP1A series water chillers are air-cooled monoblock units, 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 pure flammable refrigerant gas of category A3, with a GWP of 1. They do not contain PFAS and are suitable as retrofit solutions to replace the R407C refrigerant.

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