The NC25 was originally developed in the early 1980s as one of the first electronic refrigeration and HVAC control systems. This controller has been used in a variety of different applications from refrigeration racks to industrial boilers and chillers. In the mid-1990s Danfoss discontinued production of this hardware in favor of the next iteration, the Danfoss AKCESS 55.
