Freezers with external rotary knobs

External rotary knobs

— controls by means of rotary knobs. Such knobs, as well as other controls, can be installed both inside the unit (they do not spoil the appearance of the freezer, but you have to open the door to control it) and outside (external regulators for quick access to control can make it difficult to install the device in the interior of the room). In general, this is the simplest and most inexpensive option used in units of the appropriate level. However, even this is quite enough — especially if the freezer works in more or less constant temperature conditions (for example, in a home or office kitchen). In many cases, the matter is limited to selecting the appropriate knob position once and then not touching the settings at all. In addition, the unambiguous advantages of this type of control are reliability and ease of repair.
