Product Highlights
Smart Innovation: Preserve the quality of your food items for longer using this appliance’s Vacuum Compartment. This technology keeps air and oxygen levels low to ensure your food items like meat, fish, and dairy stay fresh and flavourful1.
Advanced Cooling and Purification: Achieve optimal freshness with its combination of Inverter x Dual Fan Cooling technology, featuring dedicated fans and Eco Thermo-Sensors in each compartment for precise temperature control. Activate Quick Cooling mode to enjoy approximately 29% faster cooling2. Additionally, the Triple Power Filter effectively removes odours3 and up to 99% of bacteria4.
Versatile Compartment Solution: Enjoy flexible storage options! This quad-door refrigerator equips two dedicated drawers for produce, a Select Case for dry foods or veggies, and a vacuum compartment. In addition, the freezer features a flexible Selectable Zone with customisable mode settings, a standard three-basket/bin section, and an automatic ice maker.
Ice On-demand: Enjoy refreshingly cool drinks on demand with the Hitachi fridge’s automatic ice maker. Just fill the water tank and let it handle the work. You can also activate the Quick Freezing mode and speed up the ice production by up to 24%5.
Sleek and Stylish: Upgrade your kitchen’s aesthetic with the Hitachi Quad Door Fridge Freezer’s luxurious black glass finish and flat doors with recessed handles. It also has an aluminium interior and energy-efficient LED lighting to create a brighter, cleaner space.
1 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.
2 Tested by Hitachi. Comparison between Quick Cooling mode ON and OFF.
3 Triple Power Filter that catches and removes 7 odour components (Tested by Hitachi. The type of odours: Methyl Mercaptan, Ammonia, Acetaldehyde, Trimethylamine, Propanal, Hexanal and Acetic Acid).
4 Thus also provides a sterilising effect. Combining the properties of Activated Carbon, Zeolite and Manganese Oxide (catalyst), the filter greatly reduces the percentage of odours present over time. Testing organisation: Boken Quality Evaluation Institute. Testing method: Film adhesion method (JISZ2801). Name of processing component: Filter. Sterilisation method: Application of oxidation catalyst to filter. Subject: Bacteria trapped in the filter. Test results: 99% sterilised after 24 hours, achieved using the filter alone. No effect on the environment and food inside the refrigerator.

A Fridge Designed with Families in MindWe bought this 638L 4 Door Fridge last month and I am absolutely loving our Hitachi 638L 4-Door fridge. From the moment we started using it, the design and functionality really stood out.
The fridge has a sleek, modern look that fits perfectly in our home, and the spacious interior makes organising food easy and convenient. One of our favourite features is the child lock, which adds peace of mind and makes it especially practical for a family household.
Overall, this fridge is stylish, well-designed, and very user-friendly. It has been a fantastic addition to our home, and we are extremely happy with its performance. Highly recommended.

Few things can be betterI bought mine 1 month ago, but few things come to my mind. First, the black mirror is really easy to see any marks and finger prints. Second, the selectable zone is amazing, but too big for chill/meat or soft freeze, then make the freezer zone which on the right Conner is too small, ideally I just need one or two shelf are chill/meat or soft freeze, not a whole section, otherwise freezer zone is not enough. Last, the 2 top glasses in the refrigerator seems like can not leave heavy items in the middle of it, it is shaking and feel unsafe or possibly break the glass.

Jappenese build qualityWhat sold me the fridge was the fact it is made in Japan. The construction of the plastic draws and glass shelves allowed for many adjustments to your particular needs. My model is 5 years old now and still behaves and looks new. No rubber falling off, shelves breaking or the door not quite closing problems unlike some fridges I put up with previously. The fridge motor is a inverter. Meaning it doesn't go on and off at full power but like driving a car revs the motor to just cool or really cools....most of the time it just idles barely running... Running costs are way down. I like having a fridge with glass front doors... Not shiny metal or painted or plastic.. Glass for easy cleaning with no marks or scratches.

Excellent purchaseI bought this fridge 2 days ago and it is the best thing I did (I mean, me and hubby)! We are 4, we needed a bigger fridge and freezer. So much space, mirrored, nice features. Fits perfectly in our kitchen. Best purchase so far. 5 Years warranty, excellent brand.

Great fridge 👍🏻We purchased this refrigerator a week ago, and it has fully met our expectations. It offers a perfect combination of reliability and practical features. The design is aesthetically pleasing both inside and out, and it operates almost silently. We were particularly impressed with the ice maker, which does not require a water line, takes up minimal space, and seems more reliable compared to traditional plumbed ice maker solutions.
The only downside is the lack of lighting in the lower compartments (freezer), but this might also be the case with other brands.

Stylish, makes a statement in the kitchen.[This review was collected as part of a promotion.] We have only had the fridge for 3 weeks now and still trying to get used to having a French door configuration. Looks really stylish and makes a real statement in the kitchen with everyone making comment when they see it. Don't be fooled by the sales, the glass front does pick up fingerprints real easy. The vacuum draw is more than just a gimmick it does really work well. The set back handles are stylish and will serve the wear and tear better than regular traditional handles, though they seem to pick up debris easy. The door space is pretty narrow and the configuration for taller bottles like milk, water, juice, wine etc is limited. Overall its a great fridge and appears a much higher quality than the major big brands that we have previously chosen.

Slick and efficient!I bought this fridge for my first house and I am obsessed with it. The black glass instantly made my older kitchen look more modern and the layout and functions of the fridge are a game changer. The automatic ice maker is genius. 10/10 would recommend everyone to buy this fridge
