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.

Vacuum Compartment

Nutrition Retention

Stay healthy. A vacuumed environment prevents oxidisation and retains nutrients inside the food.

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.

Approx. 2°C Moisture Air Keeps Food Fresh

Moisture Cooling

Optimum-moisture chilled air and lower temperature of approx. 2°C retains flavours and freshness.*1

Retains 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.
