SIGMA / SIGMA AFC: Liquid Chillers with Integrated Heating Unit (R407C)
The water-cooled chillers of the SIGMA Series and air-cooled chillers of the SIGMA AFC Series are designed to produce process chilled water for cooling industrial plants. These are fully self-contained monoblock refrigeration units featuring a hydraulic circuit complete with a closed storage tank and a circulation pump.
In addition to chilled water production, the SIGMA Series chillers can produce process hot water (up to 90°C) for the thermoregulation of industrial processes.
Depending on the chosen version, the units are equipped with 1 or 2 cooling circuits (+6°C / +18°C – C1 and C2 versions) and 1 or 2 heating/cooling circuits (+6°C / +90°C – H1 and H2 versions).
