In the 4th product line of refrigerators from the German company Bosch, models of the "Standard" level are concentrated. Their freezer is located mainly from the bottom, less often — above the refrigerator. Also in the family there are specimens without a freezer at all, which make up the overwhelming minority.

Against the background of the basic models of the 2nd series, refrigerators of the "Standard" class stand out by the shape of hidden door handles — they are cut vertically in the doors. The equipment control panel can be located on the facade, or it can be hidden behind the upper door. The operation of the family devices is fueled by both traditional compressors and energy-efficient drives with inverter control. Advanced squad models have two independent cooling circuits.

Bosch Series 4 refrigerators use separate VitaFresh boxes for vegetables/fruits and fish/meat with temperature and humidity control.

Technologically, the Bosch Serie 4 are very well-versed. The refrigerators of the series use Full No Frost auto-defrosting, LowFrost freezer icing reduction technology, extended VitaFresh freshness zone. In the boxes of the latter system, it is possible to adjust the temperature and humidity with a special slider. You can store fresh vegetables and fruits, as well as meat and fish in them. The interior space of the Series 4 refrigerators is illuminated by a bright LED backlight.
