Claim Text:
1. A method for recovering and depurating a coolant comprising the steps of: prearranging at least one passage duct of said coolant entering or exiting an apparatus having a distal end configured to be connected to a high and/or low pressure connection of a refrigeration circuit, said passage duct having a proximal end connected to an inlet fitting and/or an outlet fitting of said apparatus; recovering said coolant by suction from said refrigeration circuit and depurating said coolant through a recovery and depuration pathway; receiving a depurated coolant from said recovery and depuration pathway in a collection container; reintroducing said depurated coolant through a reintroduction pathway between said collection container and said inlet fitting and/or said outlet fitting into said refrigeration circuit; prearranging a bypass pathway that branches off from said reintroduction pathway, said bypass pathway comprising a bypass fitting which can fit with said distal end of said passage duct, arranging said passage duct in a recirculation configuration, in which said distal end is connected to said bypass fitting and said proximal end is connected to said inlet or outlet fitting; and operating a recirculation of said depurated coolant drawn from said collection container through said bypass pathway so that said depurated coolant enters said distal end and passes through said passage duct from said recovery and depuration pathway up to said collection container, washing impurities from said distal end and said passage duct and being depurated again.
