In coolers, the cooling system is the same as for water fountains that operate with a condenser cooled by forced convection. The evaporator exchanges heat by direct contact with the juice deposited on the surface of the vat. Thanks to the circulation pump, the heat exchange is faster and therefore more efficient. In addition, the pump prevents the decanting of sugar, that is, its deposit at the bottom of the compartment.
The temperature of the juice is controlled by a thermostat and must be between 8 ° C and 10 ° C.
