Abstract

An evaporator of condensed fluids produced by refrigerating devices comprises a resistor (3) arranged within or immediately below the bottom of a container (2) which collects the fluid to be evaporated, and a level sensor (4), of the capacitive type, able to detect a predetermined maximum value (6') and a predetermined minimum value (6), arranged in a casing which prevents it from directly contacting the fluid. There is provided a circuit for controlling the power of the resistor by means of a program which takes into account the level reached by the fluid in the basin.
