Protton's unique 3 door format offers benefits that no other refrigerator in it's class has. It provides the largest* 32 L fruits and vegetables storage space, prevents odour mixing and ensures better cooling retention owing to 3 separate zones for different storage needs. Protton world series is powered by 6TH SENSE ActiveFresh Technology ensures up to 2X freshness to your fruits and vegetables - by preventing excessive ripening, maintaining their natural moisture and preventing 99.9% bacterial growth. The refrigerator's unique 3 door format gives you an exclusive bottom drawer – the Active Fresh Zone – for fruits and vegetables. This prevents odour mixing keeping fruits and vegetables fresher for a longer duration. Zeolite Technology prevents excessive ripening of fruits and vegetables by absorbing ethylene emission from them. This reduces the sugar content of fruits and vegetables thereby ensuring up to 2X more freshness. In ordinary refrigerators, the cold air comes directly in contact with fruits and vegetables and robs them of their intrinsic moisture. But in Protton world series refrigerator, the cold air flows around the compartment, keeping its contents cool while retaining their moisture and natural freshness. A special anti-microbial additive, present in the material of the compartment itself, helps to kill up to 99.9% microbes, thus providing lifelong protection against contamination. To ensure that each compartment receives the precise cooling it requires and to prevent odour mixing, the Airbooster system controls the circulation of cold air throughout.
