IC100 is Dixell's answer to real management and control requirements of chiller unit and heat pump single circuit

( gas and water reversibility ), with up two compressors or a single compressor with capacity stages, by means of
a compact instrument, the possibility of controlling and managing system like:

air / air  "roof top"
air / water
water / water
motor-condensing
refrigeration dryers

This family of advanced multifunction controllers is available in CX or L formats to fit in with whatever space is available.
