400PSI Nitrogen Purging Kit

400PSI Nitrogen Purging Kit

Q: What nitrogen flow rate should I use when purging and brazing?

For purging, AWS D10.13/D10.13M recommends a flow rate of 25 CFH (12 LPM), with the purging duration depending on the pipe or tube length and size. When brazing tubes under 3″ in size, the manual recommends reducing the nitrogen flow to approximately 5 CFH (2.4 LPM)

Q: Can I use the 400 PSI Nitrogen Purging Kit to pressure test an HVAC/R system?

Yes. The 400 PSI Nitrogen Purging Kit can be used to pressure test HVAC/R systems with nitrogen. The regulator provides adjustable outlet pressure up to 400 PSI, allowing the technician to set the required test pressure for the system being serviced. Always follow the equipment manufacturer’s specified test pressure and procedures.

Q: Why should nitrogen flow be reduced during brazing?

Once the initial purge is complete, only a low flow of nitrogen is required during brazing. This maintains a nitrogen atmosphere inside the tubing to help minimize oxide formation, while avoiding unnecessary nitrogen flow through the system. For tubes under 3″, the manual recommends approximately 5 CFH (2.4 LPM) during brazing.

Test and purge refrigeration and air conditioning systems easily with our Nitrogen Purging Kit. Pressure check HVAC and Refrigeration lines, and purge pipes prior to brazing to protect the joints from oxidation. This kit can also be used to flush condensate drain lines. The compact size is suitable for use in hard to reach areas or where space is limited.

Available in 3 pressure variants, these nitrogen purging kits include UL Approved regulators, with easy-to-read contents and flow gauges that have been precision engineered for trade use.

Application: Engineered for HVAC technicians for purging & testing of HVAC/Refrigeration systems and flushing drain lines.
