Hitachi’s Platinum Catalyst with Ruthenium Vacuum Compartment is engineered to reduce oxygen levels by maintaining approximately 0.8 atmospheric pressure. This vacuum environment helps slow oxidation so meat, fish, and dairy can remain nutritious and fresh without freezing, while selectable temperature options allow precise storage at around -1°C or +1°C to protect texture and flavour. The same vacuum technology also supports faster seasoning, helping marinades absorb more efficiently to streamline meal preparation.
For fruits and vegetables, the Aero-care Vege Compartment combines an improved airtight seal with Platinum Catalyst performance to help control humidity and support nutrient retention. By managing respiration and limiting moisture loss, produce stays crisp, vibrant, and appealing for longer. Sensor Cooling further supports freshness by keeping the lower shelves at approximately 2°C, adjusting cooling power automatically as conditions change.
In the freezer, Delicious Freezing technology uses a large aluminium tray and temperature sensing to freeze food rapidly past the maximum ice crystal formation zone. This helps reduce cell damage, minimise drip loss after thawing, and maintain texture and flavour in both fresh and cooked foods. Energy performance is supported by Vacuum Insulation Panels and advanced Frost Recycle Cooling, which circulates chilled air using recycled frost for efficient cooling even when the compressor is not running.
With auto open doors and drawers, adjustable shelves and pockets, dedicated ice storage, and a modern touch screen controller, the R-ZX740RA is designed to make everyday storage and access feel effortless, elegant, and intelligently controlled.
