NAVAC has introduced the industry's first smart refrigerant charger. The NRC62i Smart Charging Unit's powerful twin-cylinder vacuum pump rapidly evacuates an HVAC system to the vacuum level calculated by the machine’s algorithm, with progress displayed digitally via a monitor and wireless scale. 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.
