Abstract: A dual tank refrigerant delivery apparatus including a refrigerant tank housing a first storage tank, a second storage tank, and a refrigerant delivery system positioned therein, the refrigerant delivery system adapted to supply a first refrigerant to the first storage tank and a second refrigerant to the second storage tank, a tank recess on the housing for receiving a refrigerant resupply tank, a first refrigerant hose for connecting to a first refrigerant resupply tank, a second refrigerant hose for connecting to a second refrigerant resupply tank, wherein the first refrigerant is supplied from the first refrigerant resupply tank through the first refrigerant hose and refrigerant delivery system to the first storage tank, and wherein the second refrigerant is supplied from the second refrigerant resupply tank through the second refrigerant hose and refrigerant delivery system to the second storage tank.

Abstract: Apparatuses, methods, and systems for adjusting scale(s) of a refrigerant recovery system (RRS) are described. The RRS can determine pressure and weight measurements of content within a refrigerant storage tank. The RRS can determine weight measurements of content within oil storage containers. The RRS can compare the pressure and weight measurements to thresholds to determine whether the scale(s) require adjusting, whether the RRS should be locked to prevent further use of the RRS until after servicing of the RRS, or whether additional functions of an operating state of the RRS should be performed. The RRS can comprise a processor to automatically adjust the scales, determine the pressure and weight measurements, and compare pressure and weight measurements to the thresholds. Locking the RRS can prevent the RRS from recovering refrigerant from a cooling system, such as an air conditioning system in a vehicle.
