Product Description

PSA Nitrogen Generator System for Metal Heat Treatment Furnace

Product Overview

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.

Why Nitrogen in Thermal Processing

Safety

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.

Diluent

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.

Atmosphere

Nitrogen can serve as the sole constituent of furnace atmospheres, particularly at lower temperature ranges. Higher purity nitrogen generally produces better heat treatment results.

Typical Applications

Sealed Quench Heat Treatment
Annealing & Brazing
Sintering & Carburizing
Bright Heat Treatment
Powder Metallurgy
Protective Atmosphere Furnaces
Metal Component Heat Treatment
Stainless Steel Heat Treatment

Industry Challenges Solved

Metal oxidation and surface discoloration
Inconsistent heat treatment quality
Excessive material loss and rework
Production interruptions from insufficient nitrogen supply
High costs of bottled or liquid nitrogen
Difficulty maintaining stable furnace pressure and atmosphere

Technical Highlights

German-style PSA process with molecular sieve packing technology extends unit service life beyond 10 years
Patented adjustable adsorption towers maintain molecular sieve bed stability
Waste gas vortex discharge completes regeneration within 15 seconds
Automatic venting of non-compliant nitrogen with online purity analysis
Advanced load adaptation technology reduces electricity consumption by 20%
Multi-stage spiral silencer maintains noise below 80 dB(A)
Fully automatic PLC control with touch-screen HMI and remote monitoring

Purity Selection Guide

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.

Frequently Asked Questions

What nitrogen purity is required for heat treatment?

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.

How do I determine the required nitrogen capacity for my furnace?

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.

What nitrogen pressure does a heat-treatment furnace require?

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.

Is nitrogen dew point important for heat treatment?

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.

Can one nitrogen generator supply multiple heat-treatment furnaces?

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.
