Product Overview
Hitachi RZX740RAXK | 735L French Door Fridge Black Glass

735 Liter Fridge with Black Glass finish and 4 -star Energy Star Rating. Its auto door technology provides a delightfully-easy door opening experience like never before. Even if the refrigerator and freezer are fully packed, doors can be opened automatically just by touching a button. The door also features an intuitive touch control panel display where you can control the fridge settings without needing to open the fridge.
VACUUM-SEALED FOR FOOD FRESHNESS
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.
REFRESHING TECHNOLOGY MAINTAINS 0.8 ATM VACUUM1
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.
SENSOR COOLING
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.2
AERO-CARE VEGE COMPARTMENT WITH PLATINUM CATALYST
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.
VIP – VACUUM INSULATION PANEL TECHNOLOGY
VIP is a thin panel with a very fine glass fibre vacuum inside, giving an extremely high heat insulation performance - much higher than that of Urethane, a conventional insulation material. It prevents external heat from escaping to achieve exceptional energy savings. Cooling retention is 15 hours, with the highest heat insulation performance during power cut.
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. The effect may differ depending on conditions and amount of food stored.

Why Buy?
Vacuum-sealed freshness for households that cook from scratch
This Hitachi French door refrigerator uses a sealed vacuum compartment held at approximately 0.8 atmospheric pressure to reduce oxygen around stored meat, fish and dairy, slowing oxidation so fresh produce keeps its quality for longer between shops. At 735 litres across multiple drawers, it suits kitchens that buy in volume and cook often.
A dedicated sensor-controlled compartment holds the lower shelves at a steady 2°C, while the Aero-Care vegetable drawer uses a Platinum Catalyst and improved airtight seal to manage humidity for fruit and vegetables. Vacuum Insulation Panel technology cuts heat transfer more effectively than conventional urethane insulation, supporting the 4-star energy rating and giving 15 hours of cooling retention if the power drops out. Auto door opening works via a light touch even when drawers are fully loaded, and the external touch panel lets you adjust settings without letting cold air escape.
Finished in black glass at 880mm wide, it reads as a considered fridge freezer rather than a bulky appliance, sitting comfortably in contemporary kitchens. Multi-drawer separation keeps different food categories at their ideal conditions, reducing cross-contamination and food waste in daily use.

- You buy fresh meat, fish and dairy in volume and want it to last longer
