from Japan

Hitachi patented sealed-structure design and
vacuum pump maintain 0.8 atmospheric pressure
and keep away direct cold air.

Fresher Foods
Makes
You the
Best Cook!

Goodbye Oxidisation &
Dehydration

Hello to Healthy! Freshness!
and Speedy Cooking without the needs to defrost.

Features

Our Refrigerators are
Made in Japan

And Stocked with Innovative Features

Harnessing the best of Hitachi technology, we derive immense pleasure in delivering eco-friendly refrigerators through proprietary technologies.
Its unique Platinum Catalyst found in both the Vacuum and Aero-care Vege Compartments, helps sustain freshness of stored food. Other complementary features like Vacuum Insulation Panels and advanced Frost Recycling Cooling* work in synergy for greater energy efficiency.
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.

* Moisture Cooling for R-KWC/KW570K, R-HW610J and R-HW530J.

Vacuum-sealed for
Freshness

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.

Nutrition Retention

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

Quick Seasoning

Quick seasoning is made possible because the Vacuum Compartment removes air from stored food, enabling seasoning to be absorbed at a faster rate.*4 So, with less time required for seasoning and cooking, 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.

Vacuum Compartment

Hyo-on Temperature

The region from 0°C to the temperature that starts to freeze food (the freezing point) is called the "Hyo-on range". Utilising the "Hyo-on range" brings many benefits. If we take fish as an example, the freezing point is -2°C. If fish is stored between 0°C to -2°C, its freshness can be maintained without freezing it.

Flexible Storage

Selectable Zone

The Selectable Zone feature is Hitachi’s unique technology that allows you to customise mode setting of refrigerator, vegetables* and freezer for each lower compartment based on your storage and lifestyle needs.

Freezer, Refrigerator, Vegetables

* At lower mode setting of refrigerator.

Selectable Zone

Cooling Switch Technology

Control the cooler, the flap of the cold air path and the large air volume fan according to the zone setting. When "frozen" is set, a large amount of cold air is directly channelled into the container and cooled to freezing point. Refrigerated food and vegetables are stored in a "refrigerated" setting, as heat transfer from the cooler can be used to lower the temperature inside the container. This achieves refrigeration temperature while suppressing the inflow of cold air.

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.
