The Hitachi Solution for Powerful Refrigeration Plus Exceptional Energy Saving. It provides optimum cooling in both the freezer and the refrigerator compartments, something a single fan can’t do. Improved Dual Fan Cooling ensures energy saving and powerful cooling, supported by the Eco Thermo-Sensor in each compartment detecting any temperature changes at all times.
Hitachi refrigerators have two Eco Thermo-Sensors, one in the freezer compartment and the other in the refrigerator compartment. The sensors detect any temperature changes separately to enable the ideal temperatures to be maintained in each of the compartments at all times.
