Overview
The Huayisanpu PGN-16L PSA Nitrogen Generator is an industrial-grade, on-site nitrogen supply system engineered for continuous, reliable operation in laboratory and light industrial environments. It employs pressure swing adsorption (PSA) technology—utilizing high-efficiency carbon molecular sieve (CMS) beds in a dual-tower configuration—to separate nitrogen from ambient compressed air. This process exploits the differential diffusion rates of oxygen and nitrogen molecules under elevated pressure, enabling selective adsorption of oxygen, CO₂, moisture, and trace hydrocarbons while allowing high-purity nitrogen to pass through. The system delivers nitrogen at flow rates up to 16 L/min and purity levels adjustable between 99.0% and 99.99%, with real-time purity monitoring via integrated electrochemical or thermal conductivity sensor (depending on configuration). Designed for plug-and-play deployment, the unit requires only a stable 220 V AC power supply and ambient air intake—no external compressed air source is needed, as it incorporates a built-in oil-free scroll compressor. Its compact footprint (620 × 510 × 820 mm) and self-contained architecture eliminate civil works, reducing total cost of ownership versus liquid nitrogen delivery or high-pressure cylinder logistics.
Key Features
- Integrated oil-free scroll air compressor ensures clean, dry feed air without external filtration dependencies
- Dual-tower PSA architecture with automatic valve sequencing for uninterrupted nitrogen production and extended CMS service life
- Real-time nitrogen purity display (0.1% resolution) with configurable alarm thresholds for process-critical applications
- Programmable pressure regulation (0.1–0.4 MPa) and manual flow control (0–16 L/min) for precise matching to downstream instrumentation demands
- Automatic pressure-triggered start/stop logic: compressor activates when storage tank pressure falls below 0.4 MPa and deactivates at 0.6 MPa—reducing energy consumption and mechanical wear
- Onboard dew point monitoring (–40 °C to +5 °C range) and integrated coalescing/molecular sieve dryer stage ensure consistent low-moisture output compliant with ISO 8573-1 Class 2 specifications
- CE-aligned electrical safety design with grounded chassis, overpressure relief valve (>1.0 MPa burst rating), and thermal overload protection
- Low-noise operation (<55 dB[A]) suitable for shared laboratory spaces and QC environments
Sample Compatibility & Compliance
The PGN-16L is compatible with a broad spectrum of nitrogen-dependent analytical and process instruments—including GC carrier gas modules, LC-MS nitrogen curtain gas inlets, nitrogen blow-down concentrators, glovebox purging systems, and inert atmosphere reactors. Its output meets ASTM D6349-20 (Standard Guide for Gas Purity Requirements in Analytical Instrumentation) for mid-to-high purity applications. While not certified to FDA 21 CFR Part 11 out-of-the-box, the unit supports GLP/GMP workflows when paired with validated external data loggers and audit-trail-capable software (see Software & Data Management). All internal wetted materials—including stainless steel piping, CMS beds, and solenoid valves—comply with USP and ISO 10993 biocompatibility guidelines for non-contact gas handling. The system accepts ambient air meeting ISO 8573-1:2010 Class 4 (solid particles), Class 4 (water), and Class 2 (oil) as feed input; optional pre-filtration kits are available for non-conditioned environments.
Software & Data Management
The PGN-16L operates via embedded PLC-based logic with no proprietary software dependency. All operational parameters—including tower cycle timing, pressure setpoints, purity calibration offsets, and runtime diagnostics—are accessible via front-panel membrane keypad and LCD interface. For integration into centralized lab infrastructure, analog 4–20 mA outputs are provided for nitrogen purity and outlet pressure signals, enabling connection to SCADA, LIMS, or building management systems. Optional RS-485 Modbus RTU communication module (sold separately) allows remote status polling, event logging, and alarm forwarding. While the base unit does not include electronic audit trails, its deterministic control architecture supports third-party validation per GAMP 5 Annex 11 requirements when deployed with compliant data acquisition hardware and SOP-defined change control procedures.
Applications
- Gas chromatography (GC) carrier and detector gases for routine QA/QC and research-scale separations
- Nitrogen purge and blanketing in pharmaceutical packaging lines, solvent recovery systems, and API synthesis reactors
- Oxygen-sensitive sample preparation for ICP-MS, XRD, and electron microscopy specimen handling
- Controlled-atmosphere storage for reference standards, hygroscopic reagents, and calibration gas mixtures
- Food and beverage packaging—modified atmosphere packaging (MAP) line support where 99.5%+ purity suffices for shelf-life extension
- Electronics manufacturing—component soldering flux shielding, SMT reflow oven inerting, and wafer-level passivation
- Environmental testing chambers requiring stable, low-oxygen environments for accelerated aging studies
FAQ
What is the recommended feed air quality for optimal CMS performance?
Ambient air must be filtered to ISO 8573-1 Class 4 particulate, Class 4 water, and Class 2 oil. Use of the factory-recommended pre-filter kit (part #PGN-F1) is strongly advised in dusty or humid locations.
Can the nitrogen purity be calibrated in-house?
Yes—the unit includes user-accessible calibration mode for the purity sensor using certified 99.99% N₂ reference gas. Calibration procedure is documented in Section 4.2 of the English-language Operation Manual.
Is the system suitable for continuous 24/7 operation?
Yes. Designed for unattended duty cycles exceeding 8,000 hours/year, with CMS bed lifetime rated at ≥20,000 hours under nominal load (12 L/min @ 99.9% purity). Annual preventive maintenance includes filter replacement and valve actuator inspection.
Does the generator require cooling water or external ventilation?
No. Passive convection cooling is sufficient. However, ambient airflow of ≥0.5 m/s around the rear heat exchanger grilles is required to maintain operating temperature within 5–45 °C.
What safety certifications does the unit hold?
The PGN-16L conforms to IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions) standards. Electrical safety follows IEC 61010-1:2010 for laboratory equipment. Full CE Declaration of Conformity is supplied with shipment.
