Jianhu XW-FC Series Air-Cooled Xenon Arc Weathering Test Chamber

Overview

The Jianhu XW-FC Series Air-Cooled Xenon Arc Weathering Test Chamber is an engineered environmental simulation system designed to replicate the full solar spectrum—including ultraviolet (290–400 nm), visible (400–800 nm), and near-infrared (800–2500 nm) radiation—under precisely controlled temperature, humidity, and irradiance conditions. Unlike water-cooled systems, this air-cooled configuration eliminates dependency on external chilled water infrastructure, enabling rapid deployment in standard laboratory or QC facility environments. The chamber employs a high-stability xenon arc lamp with precision optical filtering to match CIE No. 85 reference spectral irradiance, ensuring compliance with key international weathering standards including ISO 4892-2, ASTM G155, and SAE J2527. Its architecture supports accelerated aging protocols for polymeric, coated, composite, and elastomeric materials used in automotive exteriors, consumer electronics housings, architectural coatings, and outdoor textiles.

Key Features

• Modular air-cooling system with dual-stage centrifugal fans and intelligent thermal load balancing—eliminates condenser water loops and reduces installation footprint
• High-fidelity spectral output via quartz envelope xenon lamp + borosilicate outer filter + optional UV-enhancing inner filter (e.g., Daylight-Q/B)
• Real-time irradiance monitoring using calibrated silicon photodiode sensor traceable to NIST standards; closed-loop feedback control maintains ±3% irradiance stability over time
• Independent humidity control via steam generator and desiccant-assisted dry-air injection—achieves stable 20–98% RH across operational temperature range (−10°C to +80°C black panel)
• Programmable exposure cycles with multi-segment profiles: light-only, light + spray, dark + condensation, and sequential UV/visible/IR modulation
• Stainless-steel interior chamber (304 grade), IP54-rated electrical enclosure, and integrated safety interlocks compliant with IEC 61000-4 EMC directives

Sample Compatibility & Compliance

The XW-FC accommodates flat-panel specimens up to 300 mm × 300 mm × 50 mm (standard rack), with optional custom fixtures for curved or irregular geometries (e.g., smartphone casings, automotive grilles). It supports standardized sample mounting per ISO 11341 and ASTM D7869, including backside ventilation and non-reflective substrate support. All operational parameters—including irradiance setpoint, chamber air temperature, black panel temperature, relative humidity, and spray duration—are logged with timestamped audit trails meeting GLP and FDA 21 CFR Part 11 requirements when paired with optional validated software. The system is routinely deployed in laboratories accredited to ISO/IEC 17025 and serves as a primary aging platform for R&D validation under automotive OEM specifications (e.g., GMW14872, Ford CETP 00.00-L-467, VW TL 226).

Software & Data Management

Control and data acquisition are managed via Jianhu’s proprietary WinWeather™ v4.2 software, running on embedded industrial PC with Windows IoT Enterprise OS. The interface provides real-time graphical display of irradiance, chamber temperature, humidity, and lamp voltage/current; supports up to 99 user-defined test programs with nested steps and conditional branching. All measurement data—including raw sensor outputs, alarm events, and manual annotations—are stored in encrypted SQLite databases with SHA-256 hashing. Export options include CSV, PDF reports (with embedded calibration certificates), and XML files compatible with LIMS integration. Optional 21 CFR Part 11 module enables electronic signatures, role-based access control, and immutable audit logs for regulated industries.

Applications

This chamber is routinely applied to evaluate photochemical degradation mechanisms in thermoplastics (PC, ABS, PP), powder-coated metals, silicone gaskets, OLED encapsulation films, and biodegradable packaging resins. In consumer electronics, it validates long-term color stability (ΔE* < 1.5 after 1000 h at 0.55 W/m² @ 340 nm) and surface microhardness retention under combined UV/humidity stress. Automotive Tier 1 suppliers use it to qualify headlamp lenses for yellowing resistance (ASTM D2244), while architectural coating manufacturers assess chalk resistance (ISO 2812-4) and gloss retention (ISO 2813) across 5-year accelerated exposure equivalents. The system also supports ozone exposure add-ons (EN 14312) for rubber elastomer testing per ISO 1431-1.

FAQ

What spectral filters are included by default?

Standard configuration includes Daylight-Q/B filter set (matching CIE 85 daylight spectrum); optional UV-B, Extended UV, and Window Glass filters are available for specific material sensitivity profiling.

Is lamp replacement performed onsite or requires factory service?

Lamp replacement is user-serviceable using provided torque wrench and alignment jig; average lamp life is 1500–2000 hours depending on irradiance setpoint and cycling profile.

Can the chamber be integrated into an existing lab automation network?

Yes—RS-485 Modbus RTU and Ethernet TCP/IP interfaces support SCADA integration; OPC UA gateway available upon request.

Does the system meet IEC 60068-2-5 for solar radiation testing?

Yes—the XW-FC series satisfies IEC 60068-2-5 Ed. 3.0 Annex A requirements for Method Sa (simulated solar radiation) when operated within specified irradiance and temperature envelopes.

What calibration documentation is supplied with shipment?

Each unit ships with NIST-traceable irradiance calibration certificate (valid for 12 months), temperature/humidity sensor calibration report, and full mechanical inspection record.
