Hitachi

Original Vacuum 

Preservation

Introducing Vacuum Preservation technology with platinum power catalyst to keep food fresh for longer in this Non Frost refrigerator .

With Japanese innovation, at its finest, Hitachi's uniquely designed vacuum preservation can achieve approximately 0.8atm capabilities through the use of a vacuum pump to extract air and reduce oxygen, suppressing oxidation, thus ensuring freshness of food while relating its nutrients.

 Platinum Catalyst

Odor components that come into contact with a catalyst are broken down into carbon dioxide and water

Odour components from meat and fish are broken down by the Platinum Catalyst of this new model refrigerator to generate a greater amount of carbon dioxide than the conventional photocatalyst. The carbon dioxide dissolves in the 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 item. This helps to prevent deterioration of flavor and texture due to freezing.

Radish with 10mm diameter, soaked for 3 hours. Red dye is used to show the permeation rate of the seasoning liquid.

The vacuum compartment of this  Multi-door Refrigerator removes air from stored food, allowing the seasoning to be absorbed in a faster rate*2 so that less time is required in food preparation.

The Power of Platinum

This new Fridge is 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.

Improved moisture cover for better sealing

Carbon dioxide + Perfect Humidity

Choose 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.

The figures vary according to the temperature settings in different compartments, its surrounding temperature and humidity, the frequency of doors opening and closing, amount and temperature of food newly added into the fridge and the method of usage.

Auto Drawer

Even when it's full of items and heavy, one touch is all it takes to slide out the Auto Drawer

Able to open fully

You can see all the way to the back, so you won't overlook items and forget about them so often. And even in limited space, you can easily slide open the drawer from the side

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.

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.

Indications for smart use

ECO-Operation Sign

This lights when the operation is comparatively stable. It goes out when there is a heavy load on the refrigerator such as during rapid freezing.
