Overview
The HJ Purification FX Series Ozone Generator is an industrial-grade, corona discharge-based ozone generation system engineered for controlled laboratory and small-scale facility applications. It operates on the principle of high-voltage electrical discharge across a dielectric barrier, converting ambient or dried oxygen (O₂) feed gas into ozone (O₃) with typical output concentrations ranging from 10 to 100 g/m³, depending on airflow rate and feed gas quality. Designed for continuous operation under stable environmental conditions, the FX Series integrates a built-in air dryer and cooling fan to maintain thermal stability and ensure consistent ozone yield. Its compact footprint and modular construction make it suitable for integration into biosafety cabinets, sterilization chambers, water treatment test rigs, and HVAC validation protocols—particularly where trace-level disinfection, surface decontamination, or oxidation process development is required.
Key Features
- Corona discharge ozone generation technology with ceramic dielectric barrier for uniform plasma distribution and extended electrode life
- Integrated air drying unit (desiccant-based) to reduce moisture content below 40% RH, minimizing nitric acid formation and maximizing O₃ stability
- Adjustable airflow control via calibrated needle valve (0.1–5 L/min range), enabling precise tuning of ozone concentration and mass output
- Thermal management system featuring aluminum-finned heat sink and low-noise DC cooling fan for sustained operation at ambient temperatures up to 35°C
- Front-panel LED indicators for power status, discharge activation, and over-temperature warning
- Robust powder-coated steel chassis with IP20-rated enclosure, compliant with IEC 61000-6-3 for conducted emissions
- No external oxygen cylinder required—operates on ambient air with optional external dry air supply for enhanced efficiency
Sample Compatibility & Compliance
The FX Series is compatible with standard laboratory-grade compressed air lines (oil-free, particle-filtered) and can be coupled with optional desiccant or membrane dryers for higher-purity ozone generation. It meets general safety requirements per GB/T 19001–2016 (equivalent to ISO 9001:2015) for manufacturing quality systems. While not certified to UL 61010-1 or IEC 61010-1 as a standalone Class I medical device, its design adheres to fundamental electrical safety principles including reinforced insulation, grounding continuity, and thermal cutoff protection. For regulated environments, users must validate ozone output stability, residual decomposition kinetics, and off-gas handling per internal SOPs aligned with ISO 14644-3 (cleanroom monitoring) and ASTM E2417 (ozone disinfection efficacy testing). Note: Ozone exposure limits follow OSHA PEL (0.1 ppm, 8-hr TWA) and ACGIH TLV (0.05 ppm, 8-hr TWA); appropriate ventilation and real-time ozone monitoring (e.g., UV absorption sensor) are mandatory during operation.
Software & Data Management
The FX Series is a manually operated, analog-controlled generator with no embedded microprocessor or digital interface. All operational parameters—including input voltage (220 V AC ±10%, 50 Hz), discharge current, and airflow—are set mechanically and monitored via external instrumentation. Users are responsible for integrating third-party ozone analyzers (e.g., BMT 965, 2B Technologies 106-M) and data loggers for time-resolved concentration profiling. For GLP/GMP-aligned workflows, manual logbooks or validated electronic lab notebooks (ELNs) must document run duration, flow settings, ambient temperature/humidity, and post-run verification of residual ozone decay (t₁/₂ < 30 min in air at 25°C). No FDA 21 CFR Part 11 compliance features are included; full audit trail capability requires external validation of recording systems.
Applications
- Validation of ozone-based sterilization cycles for laboratory equipment and isolator surfaces
- Microbial inactivation studies (e.g., Bacillus atrophaeus spores, Aspergillus niger) under controlled relative humidity and contact time
- Pilot-scale oxidation experiments in aqueous model systems (e.g., phenol degradation kinetics)
- Deodorization and VOC abatement testing in enclosed chamber environments
- Supporting ISO 14644-1 cleanroom classification through periodic bio-decontamination protocols
- Educational demonstrations of gas-phase advanced oxidation processes in chemical engineering labs
FAQ
Does the FX Series include an ozone concentration monitor?
No. The unit does not integrate an onboard ozone sensor. Real-time measurement requires external UV photometric or electrochemical ozone analyzers.
Can this generator be used with pure oxygen feed gas?
Yes—though not supplied with the base unit, the inlet accepts regulated oxygen (≥90% purity) via standard 6 mm push-to-connect fittings. Output concentration increases proportionally, but thermal management must be verified for extended runs.
What maintenance is required?
Quarterly inspection of the dielectric surface for dust accumulation, annual replacement of desiccant cartridge, and biannual verification of fan performance and grounding resistance.
Is ozone output calibrated at the factory?
Each unit undergoes functional discharge verification at 2 L/min airflow and 25°C ambient; however, NIST-traceable calibration certificates are not provided unless requested separately with third-party verification.
Can the FX Series be mounted vertically or in confined enclosures?
It must be installed horizontally with ≥10 cm clearance on all sides for convection cooling. Enclosed mounting requires forced-air ventilation meeting ≥20 CFM airflow at the rear exhaust port.
