Heating, ventilation, and air conditioning comprises the HVAC industry. Whether it’s for an industrial building, school, or residential neighborhood, HVAC is all around us and requires nitrogen throughout the manufacturing, testing, and ongoing maintenance. The two main areas nitrogen gas is used within HVAC are for brazing and pressure testing copper coil. Nitrogen is used during the brazing process to purge oxygen from the brazed surface. This reduces oxidation and gives a better adhesion and joint strength. Nitrogen is also used to purge the copper coils and for pressure testing. Often times, a HVAC manufacturer will pressurize the coils in before being shipped to confirm that there are no leaks. Nitrogen also prevents the formation of moisture during the leak testing process, thereby eliminating oxidation of the metal. In addition to these applications, nitrogen can also be used for gas assisted laser cutting of the sheet metal cabinets. Please see the laser cutting page for more information.

Since nitrogen makes up 78% of the atmosphere we live in, why not take advantage of it and produce an unlimited supply of nitrogen yourself? A nitrogen generator allows you to have complete control over how much nitrogen to produce and when to produce it. South-Tek Systems requires no contracts to be signed and eliminates the worry of ever missing a delivery again. Invest in a nitrogen generator today and start saving costs by up to 90%.
