A refrigerant recovery unit is provided and includes a safe purging mode. The safe purging mode allows non-condensable gases to be incrementally purged from a storage tank when the determined ideal vapor pressure is high, such as 40 p.s.i., in order to minimize refrigerant loss during purging. The purging can be done in small increments of time, pressure or mass. The storage tank can include a dip tube that extends into the liquid portion of the refrigerant in order to heat up the refrigerant in the tank with the heated recovered refrigerant.
