Uniweld’s new NV1 NitroVue™ nitrogen flow indicator was designed with convenience and function in mind. This unique tool 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 easy to see orange float ball visually confirms the nitrogen is flowing and allows the technician to first "PURGE" the copper lines at 20+ SCFH and then reduce the flow to "BRAZE" at 3-5 SCFH during the brazing process thus conserves its consumption and reduces operating cost. The technician must simply open the valve of the NitroVue™ until the float ball rises to the needed zone.
The nitrogen must be flowing to displace the oxygen inside the tubing during the brazing process, preventing internal oxidation and the resulting scale. Scale build up inside the tubing can cause blockage in the TXV and within the Air Conditioning and Refrigeration system resulting in premature failure. Realizing how important this procedure is, Uniweld developed the NitroVue™ to be efficient and incredibly simple to use. Always striving to keep customers happy and coming back for more, Uniweld embraces the ever changing HVAC industry and works to stay ahead of the curve with innovative ideas and technologies.
