One unique feature of the Samsung French Door Refrigerator 511L (RF48A4000M9/ME) is its Twin Cooling Plus technology. The powerful feature makes the fridge environment a favourable one for preserving fresh food with 70% humidity, compared to 30% in regular refrigerator units.
This ultimately keeps ingredients fresh for longer without drying out. The Twin Cooling System works by cooling the compartments of the fridge separately to block unexpected odours spreading from fridge to freezer. This ensures that frozen food retains more of its original flavour.
