Grey GSI outdoor heat pumps stand on white gravel beds, the larger twin-fan "mevoair" model carrying an R290 sticker. Behind them a white wall reads "Smart Heat Pumps, Trusted Performance", while more units, including an "AMOS" cabinet, line the stand toward the orange "Geothermal Evolution" column.
