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.
* 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 vacuum environment*1 which prevents oxidation and supports nutrient retention.

K-value is calculated and compared with Vacuum Compartment and refrigerator compartment. Freshness is calculated by K-value which 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.

Now, you can truly chill. Store your food without freezing by selecting a suitable temperature for the stored items, and help prevent deterioration of flavours and texture.
The lower 2 shelves are kept at approx. 2°C. This is lower than the regular refrigerator temperature, so your items stored here retain their freshness. The sensor detects temperature changes and adjusts the cooling power to maintain the 2°C temperature in the right lower compartment.*

* Tested by Hitachi. The effect may differ depending on conditions and amount of food stored. When shipped, “Sensor Cooling” is turned off. Turning it on increases power use by approx. 5%. When “Sensor Cooling” is on, both “Sensor Cooling” and “Auto Powerful Cooling” are active. You can‘t set just one of these functions. If you put a warm pot (around 50℃) inside, "Auto Powerful Cooling" uses approx. 10% more power than normal.
The uniquely-designed 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.
* Tested by Hitachi. Tested model : R-HXCC62X(equivalent performance to R-ZXC/WXC740WS). When storing approx. 1.8kg 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 62-96%. Humidity varies depending on the amount and type of food being stored, freshness, and operating conditions of the refrigerator. The effect may differ depending on types and amount of food stored.

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.
Aluminium tray helps food temperature pass quickly through "Maximum Ice Crystal Formation Zone (-1°C to -5°C)" and freezes food faster. This can suppress the growth of ice crystals and suppress damage to the food cells.
* Tested by Hitachi.
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. Quick freezing reduces the ice crystal size and suppress the drip loss, thus sealing in flavours of meat and fish.

and keeps food from drying out by simply placing items without needing to press any buttons.
When food is cooled from both the top and bottom, its temperature decreases more than when cooled just from the top. This reduces the temperature difference between the food and the cooler surrounding air, making moisture less likely to escape and suppress frost and dryness.

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 VIP's used vary depending on the model.

In Frost Recycling Cooling, chilled air is generated by frost formed in the evaporator. This is recycled by being sent to every compartment to cool down – even when the compressor is not running.
Through such a system, energy consumption is reduced.
