Vacuum Compartment

Vacuum Compartment

Approx. 0.8atm

*Image is for illustrative purposes only.

For Meat, Fish, Dairy and Processed Foods

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.

*Vacuum means the space where the pressure is lower than the atmospheric pressure. The pressure in the Vacuum Compartment is about 0.8atm, which is lower than the atmosphere pressure.

Freshness Preservation with New
Platinum Catalyst

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.

2 Temperature Zones

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.

DHA in Horse Mackerel

Approx. 7% More

Tested by Hitachi. The effect differs depending on models and conditions.

*K-value is an indication of freshness.

Quick Seasoning

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.

Energy Saving

Energy Saving

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.

Hitachi Original Flexible Vacuum Insulation Panel (VIP)

Large Capacity and Energy Saving

Using the conventional insulation material of urethane foam together with highly efficient vacuum insulation panels enables both large capacity and energy-saving performance.

Outer Bag, Inner Bag, Glass Wool, Glass Fiber about 4µm

*The location, shape and number of vacuum insulation panels differs depending on the model.

Hitachi Original Frost Recycling Cooling Technology with Hybrid Defrost

Effective Use of Frost for Cooling

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.

Intelligent Control

Convenient Eco Intelligent Control

Cuts power consumption by about 10 – 12% compared to that during regular operation.
(Room temperature of 16°C32°C)*

Save Mode

1LED Lighting (Inside the Refrigerator)

Lighting dims when the door has been left open for 30 seconds, to prompt the user to quickly shut the door.

2Controlled Compressor Operation

Lowers the rotation speed of the compressor.

Temperature (in Each Compartment)

Slowly cools the compartment without affecting food preservation.

Door Alarm

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.

Indications for Smart Use

ecoOperation Sign

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.

*Tested by Hitachi.
