Vacuum Compartment 
Introducing Vacuum Preservation technology with Platinum Power Catalyst to keep food fresh for longer.
Odor components that come into contact with the catalyst are broken down into carbon dioxide and water.
*Image is for illustrative purposes only.
*Vacuum means the space where the pressure is lower than the atmospheric pressure. The pressure in the Vacuum Compartment is about 0.8atm, which is lower than the atmosphere pressure, so Hitachi calls such a state as vacuum.
Hitachi’s uniquely designed Vacuum Preservation can achieve approximately 0.8atm capabilities through the use of a vacuum pump to extract air and reduce oxygen, suppressing oxidation, thus ensuring freshness of food while retaining its nutrients. Furthermore, the airtight structure of the compartment confines moisture inside, thus helping to prevent dehydration of stored food.
Odor components from meat and fish are broken down by the Platinum Catalyst to generate carbon dioxide. The carbon dioxide dissolves in water on the surface of food items to make the surface weakly acidic, which suppresses enzyme strength to minimize loss of freshness.
Selecting the Vacuum Sub Zero mode for items such as meat, fish and processed food, and the Vacuum Chilled mode setting for items such as vegetables and tofu let you store food without freezing them. This helps to prevent deterioration of flavor and texture due to freezing.
Tested by Hitachi. Comparison of storage in the new R-X7300F (equivalent to R-F7300XS) Vacuum Compartment (Vacuum Sub Zero mode) and the Refrigerator Compartment.
*K-value is an indication of freshness.
The vacuum compartment removes air from stored food, allowing the seasoning to be absorbed at a faster rate* so that less time is required in food preparation.
Radish with 10mm diameter, soaked for 3 hours. Red dye is used to show the permeation rate of the seasoning liquid.
*Tested by Hitachi. Tested using R-G6700D(functions equivalent to R-E6800X).
Drying of stored items is reduced. Now you can store opened items and dishes you want to store for a while without the need for troublesome wrapping.

Aero-care Vege Compartment
Uniquely designed to maintain freshness and nutrients in vegetables, the Aero-care Vege Compartment puts food under the power of a Platinum Catalyst, producing increased carbon dioxide to control respiration of vegetables and limiting the consumption of nutrients in the environment to prevent loss of freshness.
In addition, the improved airtight seal of the compartment increases humidity, with the Humidity Control unit also releasing excess moisture, vegetables remain in optimal condition, further ensuring they retain their freshness and nutrients.
Odor components that come into contact with the catalyst are broken down into carbon dioxide and water.
*Image is for illustrative purposes only.
Highly efficient even at low temperatures, the Platinum Catalyst developed by Hokkaido University breaks down ethylene and odor components inside the refrigerator into carbon dioxide. By maintaining a higher concentration of carbon dioxide than that in the air, Platinum preservation suppresses respiration of vegetables, and the action of enzymes on the surface of meat and fish to retain freshness and nutrients.
Professor Atsushi Fukuoka,
Close the door and the moisture cover acts as a lid over the entire vegetable compartment for improved sealing. Carbon dioxide concentration increases while moisture is kept in, helping to prevent drying. Excess moisture is released outside the case by the moisture unit to maintain the optimum amount of moisture and prevent condensation.

Energy Saving
A range of technologies such as frost recycling cooling and vacuum insulation panels, new technologies such as multi-valve control have been added to further ensure energy-saving performance.
Using the conventional insulation material of urethane foam together with highly efficient vacuum insulation panels enables both large capacity and energy-saving performance.
*The location, shape and number of vacuum insulation panels differs depending on the model.
When the compressor isn't operating, frost formed in the condenser when it was operating is used to cool the refrigerator and vegetable compartments. Frost results in energy consumption, but this is reduced by defrosting with heaters. Cooling with frost in the condenser is based on the same principle as cooling with ice.
*Image is for illustrative purposes only.
In Frost Recycling Cooling with Hybrid Defrost, chilled air generated by frost is recycled by being sent to the Refrigerator and Vegetable compartments to cool them even when the compressor is not running. Two heaters are used to defrost, thus speeding up the defrosting process. Through this system, energy consumption is reduced.
Convenient Eco
Intelligent Control
Cuts power consumption by about 10 – 12% compared to that during regular operation.
(Room temperature of 15°C – 30°C)*
LED Lighting (Inside the Refrigerator)Lighting dims when the door has been left open for 30 seconds, to prompt the user to quickly shut the door.
Controlled Compressor OperationLowers the rotation speed of the compressor.
Door AlarmThe alarm sounds when door has been left open for 30 seconds. In normal mode, alarm only sounds when door has been open for 1 minute.
Temperature (in Each Compartment)Slowly cools the compartment without affecting food preservation.
Operation SignThis lights when operation is comparatively stable. It goes out when there is a heavy load on the refrigerator such as during rapid freezing.
*Tested by Hitachi. With the R-X7300F.

Height Adjustable Shelves
The heights of 1st and 2nd shelves from the top can be adjusted to match your needs.
*When you set the height of the top shelf to the center portion
(three levels)
Large pots and tall bottles can be stored by changing the layout of height adjustable shelves.
Height can be adjusted to two levels depending on the size of the food items.
Freezer Compartment
Use as a space for rapid freezing of items. Can also be used for storage.
For small and thin food items
For small items in airtight boxes and freezer bags
For large frozen items
Use to store tall items vertically.
Large capacity ready to hold about 5.4 shopping baskets of food.
The measurements and rated capacities are based on the R-F7300XS using a 22L capacity basket.
Quick Freezing
During Quick Freezing, chilled air is sent to the freezer compartment to freeze items at a rapid rate. By placing food on the Aluminum Tray, food chills faster due to quick conductivity of the metal.
By quickly going past the maximum ice crystal formation zone where moisture in food items freezes, the growth of ice crystals will be inhibited. Damage to food cells is prevented, reducing the dripping during defrosting.

Automatic Ice-Maker
Compartment
You can enjoy clean ice anytime from bottled water that goes through the water filter. No troublesome plumbing is required, as the unit does not need to be connected to a tap. The water pump and pipe are maintenance free.
Easy cleaning with water
*1Recommended to use water with a hardness level below 100mg/L. If you use mineral water, white suspended solids will be mixed in the ice. However, this would not affect the water’s drinkability since the minerals are trapped in the ice.
With the Quick Ice-Making function, it only takes 80 minutes*2 for ice cubes to form as compared with conventional ice-making at 120 minutes.
*2Tested by Hitachi. Time taken to make ice once (12 cubes) without opening the door based on room temperature outside the refrigerator being 30°C.
With a transparent lid for easy identification for neat storage of small items such as ice cream.
Touch Screen Controller
Usually, the refrigerator projects a refined appearance with no visible control panel. Touch the MENU button and the control panel display appears on the flat surface of the door, so you can control your settings without having to open the door.
Tempered glass that's scratch-resistant and easy to wipe clean is used for the doors.
