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.
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.
Optimum-moisture chilled air and lower temperature of approx. 2°C retains flavours and freshness.*1
*1 Tested by Hitachi. The effect may differ depending on conditions and amount of food stored.
Increased volume of chilled air cools down the items faster with the Quick Cooling mode.
Cools down the pre-cooking items faster to shorten the cooking time.
Cools beverages faster.
* Tested by Hitachi. The power consumption is increased by 5% when the Quick Cooling mode is ON.
The uniquely-designed lower 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.
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.
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.
* The VIP installed area, shape and the number of VIP used on the product may differ depending on the model.

The tempered glass shelves and the door pockets can be adjusted to match the size of the food items and your needs.
