Approx. -1°C keeps the meat and fish fresh without freezing and protects the food.
Approx. -1°C keeps the fish fresh without getting frozen for 3 days.
* Tested by Hitachi. K-value compared after 3days. Tested model: R-HXCC62X(equivalent performance to R-HV490WS).
*1 K-value is calculated and compared with Extra Fresh Room and refrigerator compartment. K-value is an indication of freshness. The lower the value, the fresher the item. Value of 20% or higher is not suitable for eating raw and value of 60% or higher is not suitable for consumption. Room temperature set at approx. 20℃, without door opening/closing, and wrapping. The effect may differ depending on types or freshness of food stored and does not extend to best-before and expiration dates.

The region from 0°C to the temperature that starts to freeze food (the freezing point) is called the "Hyo-on Range". Utilising the range brings many benefits, such as fish which freezing point is -2°C. If fish is stored between 0°C to -2°C, its freshness can be maintained without freezing it.

* Tested by Hitachi. Tested model R-HXCC62X(equivalent performance to R-HW620/HW540, HV490WS).When storing approx. 1.8kg of vegetables in the Aero-care Vege Compartment (Lower case) at a room temperature of approx. 20°C for 10 days without wrapping or opening/closing the door, the humidity inside the refrigerator will be 62-96%. Humidity varies depending on the amount and type of food being stored, freshness, and operating conditions of the refrigerator. The effect may differ depending on food types, condition, and quantity.
Under the power of a Platinum Catalyst, food achieves amazing results. The increased carbon dioxide controls vegetable respiration, suppresses the loss of nutrients, and keeps the vegetables freshness longer.

A dedicated temperature sensor detects the temperature of the Delicious Freezing space, automatically switches the operation, and quickly freezes the food.
Aluminium tray helps food temperature pass quickly through “Maximum Ice Crystal Formation Zone (-1°C to -5°C )” and freezes food faster. This can suppress the growth of ice crystals and suppress damage to the food cells.

and keeps food from drying out by simply placing items without needing to press any buttons.
When food is cooled from both the top and bottom, its temperature decreases more than when cooled just from the top. This reduces the temperature difference between the food and the cooler surrounding air, making moisture less likely to escape and suppress frost and dryness.
