Features

Spaciously stylish

More space inside

Large Capacity

Store plenty of food in a spacious 575 liter interior. SpaceMax™ technology makes the walls much thinner*. So it creates more usable storage space without increasing the external dimensions or compromising energy efficiency. The flat cooling duct in the rear wall also reduces “dead space”.

The arrows indicate that the refrigerator has more storage space than before. SpaceMax™ technology allows you to store more food. The arrows indicate that the refrigerator has more storage space than before. SpaceMax™ technology allows you to store more food.

Convenience

Seamless accessibility

Easy Access Controls

Enjoy stylish, but easy control, even if you have restricted movement. The Hidden Display enhances the minimalist design as it is discretely hidden inside. The controls are within arm’s reach, even from a wheelchair, and usable with one hand, ensuring better accessibility for disabled people.

Performance

Cools evenly all over

All-Around Cooling

Make sure food is properly cooled – wherever it is. All-Around Cooling cools each compartment evenly from corner to corner*, so everything is kept at the right temperature. It continually checks the temperature and circulates cool air everywhere in the fridge through strategically placed vents. 2

Frost free freshness

No Frost
