Uniweld’s new NV1 NitroVue™ nitrogen flow indicator simplifies the purging of nitrogen during the brazing of copper tubing in air conditioning and refrigeration systems with an easy-to-read flow indicator label and a precision adjustable valve to control the low flow of nitrogen gas. The bright orange float ball and tube are fortified and protected in the aluminum body with wide-open windows for a clear view. The orange float ball visually confirms the nitrogen is flowing and allows a technician to first purge the copper lines and then reduce the flow to braze during the brazing process, thus conserving its consumption and reducing operating costs. The technician must simply open the valve of the NitroVue™ until the float ball rises to the needed zone.
