High-Purity Nitrogen Generator for Metal Heat Treatment: GASPU PD5N Series – Reliable On-Site Nitrogen Solutions

In the metal heat treatment industry, nitrogen is indispensable, serving as a critical protective and process gas for applications like bright quenching, annealing, nitriding, nitrocarburizing, welding, and powder metallurgy. To meet the industry’s demand for consistent, high-purity nitrogen, GASPU presents the PD5N Series Nitrogen Generator – a cutting-edge on-site solution designed to deliver reliable, cost-effective, and customizable nitrogen production. Engineered with advanced Carbon Molecular Sieve (CMS) technology, the PD5N Series ensures metal processors achieve optimal results while reducing operational costs and environmental impact.

Product Features & Advantages

1. Ultra-High Purity & Performance

The PD5N Series is tailored for metal heat treatment processes requiring stringent gas quality. With a nitrogen purity of ≥99.999% and oxygen content as low as ≤5ppm, it guarantees a stable, inert atmosphere to prevent oxidation, ensuring bright, high-quality metal surfaces during heat treatment. Its dew point of ≤-60℃ further eliminates moisture-related defects, making it ideal for sensitive applications like precision annealing and nitrocarburizing.

2. Efficient & Energy-Saving CMS Technology

At the core of the PD5N Series lies state-of-the-art Carbon Molecular Sieve (CMS) technology. CMS features a porous structure with micro-pores that selectively adsorb oxygen over nitrogen, leveraging differences in adsorption rates. The generator uses dual-tower design for continuous nitrogen output: while one tower adsorbs oxygen, the other regenerates via depressurization. A proprietary pressure equalization process optimizes efficiency by transferring lower-purity nitrogen between towers during regeneration, reducing energy consumption by up to 20% compared to single-tower systems. GASPU’s expertise in timing and pressure control ensures maximum CMS performance and longevity.

3. Customizable Capacity & Flexibility

The PD5N Series offers versatile capacity options from 50 to 1000 Nm³/Hour, adapting to small-scale workshops and large industrial facilities alike. It operates with an air source pressure of 0.75-1.0 Mpa and allows adjustable nitrogen-making pressure (0.1-0.6 Mpa), ensuring compatibility with diverse heat treatment equipment. Constructed with durable carbon steel and stainless steel 304, the generator withstands harsh industrial environments, guaranteeing long-term reliability with minimal maintenance.

4. Cost & Environmental Benefits

By producing nitrogen on-site, the PD5N Series eliminates reliance on bulk nitrogen deliveries (cylinders or liquid tanks), reducing logistics costs, storage risks, and carbon footprint. On-site generation ensures 24/7 uninterrupted supply, eliminating downtime due to delivery delays. Over time, it delivers significant cost savings, with a typical return on investment (ROI) within 1-2 years for medium to large-scale operations.

FAQ: Common Questions About GASPU PD5N Nitrogen Generators

Q1: How does the PD5N Series ensure continuous nitrogen supply?

A: The dual-tower CMS design enables non-stop production. While one tower adsorbs oxygen and produces nitrogen, the other regenerates by depressurizing to release adsorbed oxygen. A pressure equalization step between towers optimizes efficiency, ensuring a steady flow of high-purity nitrogen.

Q2: Can the generator be customized for specific metal heat treatment processes?

A: Yes. GASPU offers tailored solutions, including custom capacity, pressure settings, and integration with existing heat treatment lines. Our engineering team works with clients to design systems matching unique operational needs.

Q3: What maintenance is required for the PD5N Series?

A: Minimal maintenance is needed, primarily involving periodic air filter replacements and CMS inspection (typically every 2-3 years, depending on usage). The generator’s PLC control system includes self-diagnostic features to alert operators of potential issues.

Q4: How does on-site nitrogen generation compare to bulk nitrogen in terms of cost?

A: On-site generation eliminates delivery fees, cylinder rental costs, and losses from vaporization (for liquid nitrogen). For facilities using >50 Nm³/Hour, the PD5N Series reduces nitrogen costs by 30-50% annually, with rapid ROI.

Q5: Is the PD5N Series suitable for small-scale metal processing workshops?

A: Absolutely. With capacities starting at 50 Nm³/Hour, the PD5N Series is scalable for small to large operations. Compact models are available for workshops with limited space.
