Vacuum-sealed for Food Freshness
Vacuum Compartment
- The secret to longer-lasting freshness is reduced oxygen levels. Hitachi’s original vacuum preservation extracts air to maintain approx. 0.8 atm (atmospheric pressure). The meat, fish and dairy products are kept fresh and nutritious, and ready to cook without defrosting.

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

Excellent freshness preservation with Hitachi technology for keeping food fresh.
K-Value in Tuna Stored after 7 Days*
Initial Value : 8.8%
Vacuum Compartment : 27.8%(Vacuum Sub Zero Mode : Approx. -1°C)Refrigerator Compartment : 35.8%
K-Value in Chicken Breast after 7 Days*
Initial Value : 44.0%
Vacuum Compartment : 46.9%(Vacuum Sub Zero Mode : Approx. -1°C)Refrigerator Compartment : 52.3%
* Tested by Hitachi. Tested Model : R-WB64VGD0. K-value is an indication of freshness.
The lower the value, the fresher the item. K-value of 60% or higher is not suitable for consumption.
The effect may differ depending on types or freshness of food stored, and does not extend to best-before and expiration dates.

Quick Seasoning
Quick seasoning is made possible because the compartment removes air from stored food, enabling seasoning to be absorbed at a faster rate. So, with less time required for seasoning and cooking, such as for marinated seasoning or dehydrating the dried items, there’s more time for eating!

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.

Breakthrough Energy Saving
VIP – Vacuum Insulation Panel Technology
VIP is a thin panel with a very fine glass fibre vacuum inside, giving an extremely high heat insulation performance – much higher than that of Urethane, a conventional insulation material. It prevents external heat from escaping to achieve exceptional energy savings. Cooling retention is 15 hours, with the highest heat insulation performance during power cut.

Energy Saving

Provides optimum cooling in both the freezer and refrigerator compartments, something a single fan cannot do.
Improved Dual Fan Cooling with dedicated fans for each compartment ensures energy saving and powerful cooling.
This is supported by the Eco Thermo-Sensor in each compartment that detects any temperature change separately to enable the ideal temperature change to be maintained in each of the compartments at all times.

Inverter × Dual Fan Cooling
High Power Inverter Compressor
Capable of providing exceptionally powerful cooling by generating a large volume of chilled air, as well as efficient low power cooling with microcomputer control.

Inverter × Dual Fan Cooling
Dual Sensor Control
There are Two Eco Thermo-Sensors, one in the freezer and the other in the refrigerator compartment. The sensors detect any temperature change separately to enable the ideal temperatures to be maintained in each compartment.
