Master-Chill MBC models feature the newest patented technology in blast chillers/freezers with the Food Identification Controller (F.I.C.). The F.I.C. automatically adjusts blast chilling cycles with its single multi-sensor probe as opposed to multiple probes in many competitor models. The F.I.C. monitors temperatures in the core, beneath and on the surface, preventing surface freezing and degradation as well as preserving nutritional values of the food.
