An apparatus for recovering and depurating a cooling fluid having at least one passage duct of cooling fluid that extends entering or exiting the apparatus. Each passage duct has a distal end configured to be connected to a high and/or low pressure connection of high and low pressure lines of a refrigeration circuit and a proximal end connected to a coolant inlet/outlet fitting. The apparatus also includes a coolant recovery and depuration pathway, and a collection container of accumulated cooling fluid that receives depurated cooling fluid from the recovery and depuration pathway.
