Utilizing the best of Hitachi technology, we obtain immense pleasure in delivering exclusive technologies. Hitachi Made in Japan refrigerators exude external aesthetic beauty and are also made for the intelligent and innovative homes of the future. With Hitachi, you’ve got it made.
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.
*1 Vacuum is a state of lower
pressure than atmospheric pressure.
The pressure inside vacuum compartment is
approximately 0.8 atmospheres, which is lower than atmospheric pressure, so Hitachi
calls it a vacuum.
Increasing food fresh longevity with a vacuumed environment*1 which prevents oxidation and supports nutrient retention.

*Tested by Hitachi. Tested Model for vacuum compartment: R-GWC670TC (Equivalent performance to R-GW670TT) K-value is an indication of freshness. The lower the value, the fresher the item. K-value of 20% or higher is not suitable for eating raw and 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.
Vacuum technology by Hitachi reduces oxygen levels to maintain approx. 0.8 atmospheric pressure enabling food to be marinated faster, leaving you with more time to savour your meals.

ingredient freshness by suppressing bacterial growth.
* Tested by Hitachi. Moisture Cooling is not applicable for door pockets.
* Tested by Hitachi. The effect may differ depending on conditions and the amount of food stored.

*2 Factory setting will be Moisture Cooling “ON”. When the Moisture Cooling
is ON, the total power consumption is increased by approx.5%.
*3 For when the room temperature is stable and the room temperature is
approx. 32℃.
* Approximately 400 g of leaf salad (without wrap) stored for 24 hours. Room
temperature about 20℃, no door open/close. The humidity inside the cabinet is the
average humidity of the shelf space. Humidity depends on the amount of storage in the
refrigerator compartment, the food (type, condition, and amount of food), the number of
times the refrigerator door is open/close, and the operating conditions.
By suppressing dehydration of the air for the refrigerator compartment, the moisture air suppresses the dehydration of the food.
By controlling the rotational speed of the cooling fan dedicated for refrigerator compartment, it controls the whole shelves of the refrigerator compartment at approx. 2℃*1.
By using dual evaporator systems, air circulations for refrigerator will be separated and odour transfer between food in refrigerator compartment and freezer compartment will be suppressed.

Cools down
food and drink quickly by increasing the amount of cold air for a certain period.

A dedicated temperature sensor detects the temperature of the Delicious Freezing space, automatically switches the operation, and quickly freezes the food.
Aluminium tray helps food temperature pass quickly through “Maximum Ice Crystal Formation Zone (-1℃ to -5℃ )” and freezes food faster. This can suppress the growth of ice crystals and suppress damage to the food cells.
* Tested by Hitachi.
Organize Your Freezer Storage Space.
Top Case : For stocking flat items, and home freezing items.
Mid Case : For stocking frequently used items and leftovers.
Bottom Case : For stocking up bulk bought frozen foods and large items.
Vertical Storage Space : For stocking 500ml plastic bottles
The uniquely-designed compartment sustains freshness and nutrients of the vegetables and fruits with Platinum Catalyst. In addition, the airtight seal of compartment increases and controls humidity.
* Tested by Hitachi. When storing approx. 1.7kg of vegetables in the Aero-care Vege Compartment (Lower case) at a room temperature of approx. 20℃ for 10 days without wrapping or opening/closing the door, the humidity inside the refrigerator will be 68-95%. Humidity varies depending on the amount and type of food being stored, freshness, and operating conditions of the refrigerator. Effects may differ depending on the type, state and the amount of vegetables.
Under the power of a Platinum Catalyst, food achieves amazing results. The increased carbon dioxide controls vegetable respiration, suppresses the loss of nutrients and keeps the vegetables freshness longer.
