The NRC62i Smart Charging Unit from Navac is designed to provide automatic operation for consistent refrigeration system evacuation and filling. Upon reaching the calculated vacuum level, the unit automatically conducts dry operation and leak detection and commences the charging function per predetermined parameters. The NRC62i then shuts itself down once charging is complete. It is a 3-in-1 machine. In manual mode, it can be used as a simple vacuum pump, or as a digital manifold gauge, and its wireless scale can be used as a stand-alone device.
