Vacuum-sealed for
Freshness

Platinum Catalyst with Ruthenium Vacuum Compartment

The secret to longer-lasting freshness is reduced oxygen levels. Hitachi’s original preservation extracts air to maintain approx. 0.8 atm of vacuum preservation. With unique Platinum Catalyst, chilled meat, fish and dairy products are kept fresh and nutritious, and ready to cook.

Quick Seasoning

Quick seasoning is made possible because the Vacuum Compartment removes air from stored food, enabling seasoning to be absorbed at a faster rate.*3 So, with less time required for seasoning and cooking, there’s more time for eating!

Vacuum Compartment

Refreshing Technology Maintains 0.8 atm Vacuum*

Hitachi innovation at its finest and most consistent : the sealed pressure-resistant vacuum realises and maintains the vacuumed environment. A vacuum pump extracts air and reduces oxygen to achieve approx. 0.8 atm (atmospheric pressure) throughout usage.

* Vacuum means the space where the pressure is lower than the atmospheric pressure. The pressure in the Vacuum Compartment is about 0.8 atm, which is lower than the atmospheric pressure, hence, Hitachi considers this a vacuum.

Vacuum Compartment

A Tale of 2 Temperature Zones

Now, you can truly chill. Store your food without freezing by selecting a suitable temperature for the stored items, and help prevent deterioration of flavours and texture.

Vacuum Sub Zero Mode
Approx. -1°C
Vacuum Chilled Mode
Approx. +1°C

Vacuum Compartment

Approx. 2°C Cooling
Keeps Food Fresh

Sensor Cooling

The lower 2 shelves are kept at approx. 2°C. This is lower than the regular refrigerator temperature, so your items stored here retain their freshness. The sensor detects temperature changes and adjusts the cooling power to maintain the 2°C temperature in the right lower compartment.*

* Tested by Hitachi. The effect may differ depending on conditions and amount of food stored.

The Power of Platinum
for Fruits & Vegetables

Aero-care Vege Compartment with Platinum Catalyst

The uniquely-designed compartment sustains freshness and nutrients of the vegetables and fruits with Platinum Catalyst. In addition, the improved airtight seal of compartment increases and controls humidity.

Aero-care Vege Compartment

Freshness and Nutrition of Vegetables & Fruits

Under the power of a Platinum Catalyst, food achieves amazing results. With increased carbon dioxide produced, vegetable respiration is controlled and consumption of nutrients from the environment limited to prevent loss of food freshness.

Retains All the Natural Goodness of Your Food

Delicious Freezing Technology

Delicious Freezing technology seals in the original textures, flavours and nutritional value of fresh and cooked products. This is achieved by freezing food very quickly past the maximum ice crystal formation zone on a big aluminium tray.

Delicious Freezing

Seals in Flavours of Meat and Fish

When the Temperature Sensor detects the temperature of hot food, it will automatically switch the setting and freeze it very quickly to past the maximum ice crystal formation zone. This minimises dripping by reducing ice crystal size, thus sealing in flavours of meat and fish.

Breakthrough Energy
Saving Technology

VIP - Vacuum Insulation Panel

VIP is a thin vacuum-insulated panel with extremely high heat insulation performance. It achieves super energy saving compared to conventional urethane, by preventing external heat entry or internal cold air escape.

Reduces Energy Consumption

Frost Recycle Cooling Technology

In Frost Recycling Cooling, chilled air is generated by frost formed in the evaporator. This is recycled by being sent to every compartment to cool down – even when the compressor is not running. Through such a system, energy consumption is reduced.
