ChemTron WIND High-Flow Nitrogen Generator

Overview

The ChemTron WIND High-Flow Nitrogen Generator is an engineered solution for laboratories requiring reliable, on-demand nitrogen supply at scale. Utilizing vacuum-driven hollow-fiber membrane separation technology—complemented by pressure-swing adsorption (PSA)-enhanced molecular sieve conditioning—the system delivers consistent nitrogen purity across its full flow range. Unlike traditional high-pressure cylinder-based supply or cryogenic systems, the WIND operates at moderate working pressures (up to 6.9 bar), eliminating high-pressure storage hazards while maintaining compatibility with demanding analytical and sample preparation instruments. Its integrated oil-free scroll air compressor, multi-stage pre-filtration, and thermally stabilized membrane module ensure stable gas quality under variable ambient conditions (10–35 °C, 0–80% RH, non-condensing). Designed for continuous operation in regulated environments, the WIND meets foundational requirements for GLP-compliant labs and supports seamless integration into workflows governed by ISO/IEC 17025, USP , and ASTM D852 standards for instrument gas quality.

Key Features

• Integrated oil-free scroll air compressor with thermal overload protection and anti-vibration mounting—enables plug-and-play operation without external air sources
• Hollow-fiber membrane separation core with upstream molecular sieve conditioning and membrane passivation technology—ensures long-term stability of nitrogen purity without performance drift
• Multi-stage air purification train: coalescing filter + activated carbon + ultra-low particulate (0.01 µm) final filter—protects downstream instrumentation and extends molecular sieve service life
• Integrated refrigerated dryer and thermostatically controlled membrane module—achieves a guaranteed dew point of ≤ –45 °C, critical for moisture-sensitive applications such as GC carrier gas and LC-MS mobile phase sparging
• Automatic condensate drainage, runtime metering, and pressure-relief startup sequence—reduces manual intervention and enhances compressor longevity
• Front-access quick-release side panels with embedded maintenance reference labels—facilitates routine filter replacement and system diagnostics without tools
• PAE- and phthalate-free construction throughout gas-wetted components—complies with EU REACH Annex XIV and US FDA extractables/leachables guidance for pharmaceutical and clinical research use

Sample Compatibility & Compliance

The WIND series is validated for direct coupling with nitrogen-dependent laboratory instrumentation including but not limited to: nitrogen blow-down evaporators (e.g., TurboVap®, N-EVAP™), purge-and-trap concentrators, thermal desorption units (e.g., Markes UNITY™), evaporative light scattering detectors (ELSD), and solid-phase extraction (SPE) manifolds. All gas-wetted surfaces are electropolished stainless steel or fluoropolymer-lined; no copper, brass, or zinc-plated components are used. The system conforms to IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and its electrical architecture complies with CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). Optional audit trail logging and user access control modules support alignment with FDA 21 CFR Part 11 when paired with ChemTron’s optional LabLink™ software suite.

Software & Data Management

While the base WIND model operates via intuitive front-panel controls (LED status indicators, pressure gauges, and runtime counter), optional LabLink™ firmware enables remote monitoring via Ethernet or RS-485. Logged parameters include cumulative operating hours, inlet/outlet pressure differentials, dew point trend data (via optional sensor), and filter service alerts. All logs are timestamped and stored in non-volatile memory with configurable export (CSV/Excel). When deployed in regulated environments, LabLink™ supports electronic signature capture, role-based user permissions, and tamper-evident audit trails compliant with ALCOA+ principles—essential for GxP documentation integrity.

Applications

• GC carrier and detector gas supply—meets ASTM D852 Class I specifications for hydrocarbon and moisture content
• LC-MS mobile phase sparging and instrument purge—low dew point prevents column degradation and ion source contamination
• Nitrogen-assisted sample concentration in environmental, food, and forensic labs—stable flow and pressure minimize evaporation variability
• Thermal desorption tube purging and cold trap backflushing—consistent purity avoids artifact formation in VOC analysis
• Blank matrix spiking and method validation studies—absence of PAEs/phthalates eliminates interference in endocrine disruptor assays

FAQ

What is the maximum continuous flow rate supported by the WIND-80 model?

The WIND-80 delivers up to 80 L/min at 6.9 bar (100 psi), with flow stability maintained across the full 20–80 L/min operating range.

Does the WIND require external cooling water or ventilation ducting?

No. The unit relies on passive convection and optimized heat sink design; only standard ambient airflow (≥20 cm clearance on all sides) is required.

Can the WIND be used as a backup for existing cylinder-based nitrogen systems?

Yes. Its 1/4″ compression or 6 mm push-to-connect outlet interfaces allow direct retrofitting into existing gas distribution manifolds without adapters.

How often must the triple-filter assembly be replaced?

Under typical lab conditions (ISO Class 8 ambient air), replacement is recommended every 6,000 operating hours or annually—whichever occurs first.

Is third-party calibration certification available?

Yes. ChemTron offers factory-verified calibration reports traceable to NIST standards, including oxygen residual, dew point, and particulate verification—available upon request at time of order.
