Nitrogen purging system eliminates oxide deposits during brazing

Western Enterprises has announced the availability of a system that uses nitrogen for purging oxygen from AC line sets to eliminate oxide deposits during the brazing process.

This system, called the HVAC VN series, consists of a regulator with an integrated cylinder valve and a lightweight aluminum cylinder. The compact system features a built-in carrying handle with a high-impact protective shroud to eliminate exposed gauges that frequently leak and are easily broken. The system is available with a 22- or 44-cu.-ft. aluminum cylinder.
