What is the difference between a variable temperature freezer and a dual temperature freezer?

Variable temperature freezers and dual-temperature freezers are mainly distinguished from two aspects: function and application place:

1. Functional difference:

Double-temperature freezers are freezing Freezers that are separate from the refrigerator compartment cannot be interchanged with each other. Their functions are fixed and their design temperatures are obviously different.

Variable temperature freezer, also called dual-temperature integrated conversion freezer. Most of them are in one room. They can be used as either a refrigerator or a freezer as needed. They can be converted according to the adjustment of the thermostat. The refrigeration area and the freezing area are marked on the scale on the thermostat panel. When refrigeration is needed, Turn the knob to the refrigeration position, which is equivalent to a refrigeration freezer. When freezing is needed, turn the knob to the freezing position, which is equivalent to a freezer-freezer.

2. Differences in terms of application:

Dual-temperature freezers are mainly used in households. Since household ingredients are not frequently changed, dual-temperature freezers are equipped to store ingredients separately. More convenient and practical.

Variable temperature freezers are mainly used in supermarkets, hotels, and canteens. Since the ingredients in these places update very quickly, they usually change them every two days.
