Hitachi’s uniquely designed Vacuum Preservation can achieve approximately 0.8atm capabilities, suppressing oxidation, thus ensuring freshness of food while retaining its nutrients. Furthermore, the airtight structure of the compartment confines moisture inside, thus helping to prevent dehydration of stored food.
Odor components from meat and fish are broken down by the Platinum Catalyst to generate carbon dioxide. The carbon dioxide dissolves in water on the surface of food items to make the surface weakly acidic, which suppresses enzyme strength to minimize loss of freshness.
Selecting the Vacuum Sub Zero mode for items such as meat, fish and processed food, and the Vacuum Chilled mode setting for items such as vegetables and tofu let you store food without freezing them. This helps to prevent deterioration of flavor and texture due to freezing.

The vacuum compartment removes air from stored food, allowing the seasoning to be absorbed at a faster rate* so that less time is required in food preparation.
Drying of stored items is reduced. Now you can store opened items and dishes you want to store for a while without the need for troublesome wrapping.
Aero-care Vege Compartment
Uniquely designed to maintain freshness and nutrients in vegetables, the Aero-care Vege Compartment puts food under the power of a Platinum Catalyst, producing increased carbon dioxide to control respiration of vegetables and limiting the consumption of nutrients in the environment to prevent loss of freshness.
In addition, the improved airtight seal of the compartment increases humidity, with the Humidity Control unit also releasing excess moisture, vegetables remain in optimal condition, further ensuring they retain their freshness and nutrients.
Odor components that come into contact with the catalyst are broken down into carbon dioxide and water.
Highly efficient even at low temperatures, the Platinum Catalyst developed by Hokkaido University breaks down ethylene and odor components inside the refrigerator into carbon dioxide. By maintaining a higher concentration of carbon dioxide than that in the air, Platinum preservation suppresses respiration of vegetables, and the action of enzymes on the surface of meat and fish to retain freshness and nutrients.
Close the door and the moisture cover acts as a lid over the entire vegetable compartment for improved sealing. Carbon dioxide concentration increases while moisture is kept in, helping to prevent drying. Excess moisture is released outside the case by the moisture unit to maintain the optimum amount of moisture and prevent condensation.

Lock in the original colours, textures, flavours and nutritional value of fresh and cooked products with high-velocity freezing!
Food placed on the big Delicious Freezing Aluminum Tray chills faster due to the high thermal conductivity of the metal. By quickly going past the maximum ice crystal formation zone where the moisture in food items freezes, the growth of ice crystals will be inhibited, thus keeping food tasting delicious.
When the Temperature Sensor detects the temperature of hot food on the tray, it will automatically switch the setting and freeze it very quickly*.

A range of technologies such as Frost Recycling Cooling and Vacuum Insulation Panels, new technologies such as Multi-valve Control have been added to further ensure energy-saving performance.
Using the conventional insulation material of urethane foam together with highly efficient vacuum insulation panels enables both large capacity and energy-saving performance.
When the compressor isn't operating, frost formed in the condenser when it was operating is used to cool the refrigerator and vegetable compartments. Frost results in energy consumption, but this is reduced by defrosting with heaters. Cooling with frost in the condenser is based on the same principle as cooling with ice.
Cuts power consumption by about 10 – 12% compared to that during regular operation.
(Room temperature of 16°C – 32°C)*
Lighting dims when the door has been left open for 30 seconds, to prompt the user to quickly shut the door.
Lowers the rotation speed of the compressor.
Slowly cools the compartment without affecting food preservation.
The alarm sounds when door has been left open for 30 seconds. In normal mode, alarm only sounds when door has been open for 1 minute.
This lights up when operation is comparatively stable. It goes out when there is a heavy load on the refrigerator such as during rapid freezing.
Shelves and Pockets with
The heights of 1st and 2nd shelves from the top can be adjusted to match your needs. Also large pots and tall bottles can be stored by changing the layout of height-adjustable shelves on the lower levels.
Height can be adjusted to two levels depending on the size of the food items.
Large capacity ready to hold about 5 shopping baskets of food.
