Our PSA Nitrogen Generator provides reliable on-site nitrogen supply with stable purity, flow, pressure and dew point for metal heat treatment processes. By generating nitrogen directly at the production site, manufacturers can reduce dependence on nitrogen cylinders or liquid nitrogen deliveries while maintaining consistent protective atmosphere for continuous heat treatment operations.
Nitrogen does not react with most metals until extremely high temperatures, does not support combustion or oxidation, and is the least expensive industrial gas. These properties make it ideal for purging and inerting furnaces while protecting furnace linings from high-temperature oxidation.
As a diluent, nitrogen enables expensive reactive gases like hydrogen to be blended and distributed effectively across entire furnace loads, improving gas distribution throughout the furnace.
Nitrogen can serve as the sole constituent of furnace atmospheres, particularly at lower temperature ranges. Higher purity nitrogen generally produces better heat treatment results.
| Purity Range | Recommended Applications |
|---|---|
| 99.0–99.9% | Furnace purging, inerting and general air displacement |
| 99.9–99.99% | General protective atmospheres, carburizing and carbonitriding |
| 99.99%+ | Demanding protective atmospheres requiring low oxygen and moisture |
| 99.999%+ | Bright annealing, vacuum furnace backfilling and oxidation-sensitive processes |
Selection Tip: Higher nitrogen purity improves atmosphere stability and surface quality, but optimum purity should be determined by specific heat-treatment process requirements rather than simply selecting the highest available purity.

The required purity depends on the heat-treatment process. 99.9%–99.99% nitrogen is commonly used for protective atmospheres, carburizing and carbonitriding, while 99.99%–99.999%+ may be recommended for bright annealing, vacuum furnace backfilling and processes requiring very low oxygen and moisture levels.
The nitrogen generator capacity should be calculated based on the furnace's continuous consumption, peak consumption, purging requirements and operating cycle. We recommend providing the furnace type, N₂ consumption, operating hours and purge volume for proper sizing.
The required outlet pressure depends on the furnace and gas distribution system. Many applications require approximately 2–8 barg, but higher-pressure systems can be designed when required. The generator should be selected based on the pressure required at the furnace inlet.
Yes. Moisture in nitrogen can contribute to oxidation, surface discoloration and process instability. For many protective-atmosphere applications, a dew point of ≤ −40°C is commonly specified, while more demanding processes may require even lower moisture levels.
Yes. A centralized nitrogen generation system can supply multiple furnaces through a common distribution network. The system should be sized according to total demand plus simultaneous peak consumption, with appropriate buffer storage and pressure control.
