Large Capacity PSA Nitrogen Generator 400SCFM 98-99.5% Purity

Product Specification

Large Capacity PSA Nitrogen Generator for Chemical Industry | Reliable Low-Purity N2 Supply

Meeting the demanding inert gas requirements of the chemical industry requires robust, efficient, and cost-effective solutions. Our Large Capacity PSA Nitrogen Generator is engineered specifically for applications where high volumes of nitrogen at consistent purities (98% - 99.5%) are critical for safety, process optimization, and productivity.

Core Product Features & Advantages:

1. PSA Technology for Reliable Low-Purity Nitrogen:

   • Utilizes Pressure Swing Adsorption, adsorbing oxygen, moisture, and CO2 from compressed air to deliver continuous, consistent N2 gas.
   • Ideal Purity Range: Precisely calibrated for 98% to 99.5% purity, perfect for purge applications, tank blanketing, pipeline inerting, and catalyst protection common in chemical processes.
   • Low Dew Point: Ensures dry gas with a dew point of ≤ -40°C (at atmospheric pressure), preventing condensation and corrosion in systems.
   • Energy Efficient Operation: Optimized PSA cycles and system design minimize compressed air and power consumption, significantly lowering operating costs compared to liquid nitrogen or higher-purity alternatives.

2. Large Capacity & Industrial Strength:

   • High Flow Output: Capable of delivering 500 to 800 SCFM (Standard Cubic Feet per Minute) of nitrogen, catering to bulk requirements in large-scale chemical plants.
   • Robust Skid-Mounted Design: Built as a skid nitrogen generator for easy integration into existing infrastructure or new installations. Constructed with high-quality materials to withstand harsh chemical plant environments.
   • High Inlet Pressure: Designed to operate efficiently with compressed air at 8-12 barg (8-12 bar gauge), maximizing adsorption efficiency.
   • Exceptional Longevity: Engineered for a service life exceeding 20 years, providing a long-term, reliable gas source.

3. Operational & Cost Benefits:

   • Significant Cost Savings: Eliminates recurring expenses and logistical burdens associated with liquid nitrogen deliveries or high-purity cylinder swaps.
   • On-Demand Supply: Generates nitrogen continuously, exactly when and where you need it, ensuring uninterrupted production processes.
   • Low Maintenance: Highly automated system requiring minimal operator intervention. Durable construction reduces downtime and repair costs.
   • Customizable Solutions: Systems can be tailored to specific capacity, purity, pressure, and integration requirements within your chemical plant layout.

Key Technical Parameters:

Frequently Asked Questions (FAQ):

• Q: Is 98-99.5% purity sufficient for chemical industry applications? A: Absolutely. Many critical chemical processes like purging reactors, blanketing storage tanks, pipeline inerting, and preventing oxidation during transport/storage require large volumes of inert gas precisely in this purity range. Higher purities are often unnecessary and significantly more expensive to produce.

• Q: How does the dew point affect my application? A: A dew point of ≤ -40°C ensures the nitrogen gas is extremely dry. This prevents moisture-related issues like corrosion in pipelines and equipment, freezing in valves, and contamination of moisture-sensitive chemicals or catalysts.

• Q: What is the advantage of a skid-mounted design? A: Skid mounting provides a pre-assembled, pre-tested unit that is easy to move and install. It minimizes on-site assembly time and cost, allowing for faster commissioning and integration into your plant, whether retrofitting or setting up a new line.

• Q: How long does installation and commissioning take? A: Time varies based on site specifics and integration complexity. However, the skid-mounted nature significantly speeds up the process. Comprehensive installation support and operator training are provided as part of our technical services.

• Q: What maintenance is required? A: Maintenance is minimal compared to operational savings. Primarily involves routine filter changes (pre-filters for compressed air) and periodic checks/replacement of adsorbent material (typically every 5-10+ years depending on air quality and usage). Preventive maintenance programs and 24/7 remote support are available.

• Q: How does the operating cost compare to liquid nitrogen (LN2)? A: PSA generators offer drastically lower operating costs. Once installed, the primary cost is the electricity to run the air compressor. This eliminates the continuous purchase, delivery, handling, and vaporization costs associated with LN2, leading to rapid ROI, especially for large, continuous consumers.
