These units are designed for ageing wine.
The ageing process consists of exposing young or partially aged wines to all of the optimum conditions so that they develop to their full potential.
The homogenisation of the temperature operates on a thermodynamic principle and the distribution of the cold: larger production of cold air in the top part and natural homogenisation without any mechanical stirring.
The air temperature fluctuates between +10°C and +14°C. At am ambient temperature of +25°C, it is generally advisable to have the thermostat on setting 3 to ensure the liquid has an average of temperature 12°C.
The average humidity must be around 55% and 70%. The average is calculated by adding the instant minimum and maximum peaks (several fluctuations throughout the day as part of the compressor's operating and shut-down cycles) and dividing the total by two; for example (35% + 85%) / 2 = 60%.
The duration of a cycle must also be taken into consideration when calculating the average.
The thermostat located on the top panel of the device enables the relevant temperature to be adapted by making it colder (setting 1) or warmer (setting 5), however this only controls the cooling thermostat and not the heating circuit or the winter system in the device.
12°C +/-2°C
Temperature:
The air temperature is homogeneous from the top to the bottom without mechanical stirring.
This distribution of the cold prevents the use of a ventilator (generating tiny vibrations, which increase electricity consumption). At an ambient temperature of 25°C, it is advisable to have the thermostat on setting 3 to ensure the central section of the cabinet has an average temperature of
12°C.
The temperature is controlled by one or more thermostats in accordance with the technical specifications of the device ("winter" and refrigeration setting).
The thermostat located on the top panel of the device is only intended for the production of cold air and cannot be used to change the winter setting.
In ambient conditions of around +14°C or less, the compressor becomes ineffective unless used to force the cabinet to operate by setting the thermostat to a maximum (1).
