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.

Chills entire refrigerator compartment to retain flavour and freshness.
Maintain 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.

*1 Factory setting will be Moisture Cooling “ON”. When the Moisture Cooling is ON, the total power consumption is increased by approx.5%.
*2 For when the room temperature is stable and the room temperature is approx. 32℃.
*3 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.

*2 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.
Cools down food and drink quickly by increasing the amount of cold air for a certain period.

* Tested by Hitachi.
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.
VIP is a thin vacuum-insulated panel with extremely high heat insulation performance. This can reduce the thickness of insulation and keep the thermal conductivity low.
* The position number and shape of the VIPs used vary depending on the model.
