Overview
The APKJ AP—HX Walk-in Environmental Test Chamber is an industrial-grade, large-volume environmental simulation system engineered for precise, stable, and reproducible control of temperature and relative humidity (RH) across customizable internal volumes. Designed according to fundamental principles of psychrometric engineering and forced-convection thermal management, the chamber employs a dual-loop control architecture—separate PID-regulated systems for heating/cooling and humidification/dehumidification—to maintain rigorous environmental profiles required in product validation, reliability testing, and quality assurance protocols. Its walk-in configuration enables full-scale testing of oversized assemblies such as automotive ECUs, avionics enclosures, server racks, medical imaging systems, and complete electronic terminal units—eliminating the need for component disassembly or spatial compromise inherent in benchtop chambers.
Key Features
- Modular structural design with standardized interior dimensions (6 standard configurations) and fully customizable non-standard builds to accommodate client-specific footprint, height, and volume requirements
- High-efficiency multi-blade centrifugal circulation fan system ensuring uniform airflow distribution—validated per IEC 60068-3-5 for temperature uniformity ≤ ±1.5°C and RH uniformity ≤ ±3% RH across the working volume
- Industrial-grade SUS304 stainless steel interior lining (2.0 mm thickness), corrosion-resistant and non-magnetic, rated for continuous operation from –70°C to +150°C
- Exterior construction using electrostatically coated carbon steel panels integrated with rigid polyurethane insulation (density ≥ 40 kg/m³, thermal conductivity ≤ 0.022 W/m·K, closed-cell rate ≥ 95%)
- Imported color touchscreen controller with embedded RS-232C interface for real-time data logging, remote monitoring, and integration into centralized laboratory management systems
- Optional low-humidity configuration available down to 5°C / 10% RH via supplementary desiccant or refrigerated dehumidification modules
- Comprehensive safety architecture including over-temperature cutoff, compressor high-pressure protection, door interlock, phase failure detection, and automatic fault diagnosis with on-screen remediation guidance
Sample Compatibility & Compliance
The AP—HX chamber accommodates test specimens up to 4000 mm (W) × 2200 mm (H) × 3500 mm (D), supporting both static and dynamic load conditions during extended exposure cycles. It meets or exceeds key international standards governing environmental stress screening and climatic testing—including ISO 16750-4 (road vehicles), IEC 60068-2-30 (cyclic damp heat), ASTM D4332 (conditioning of plastics), and MIL-STD-810H Method 507.7 (high humidity). All units are factory-verified against GB/T 2423.3–2016 (constant damp heat), GB/T 2423.4–2008 (cyclic damp heat), GB/T 2423.1–2008 (cold), and GB/T 2423.2–2008 (dry heat), with traceable calibration documentation provided per ISO/IEC 17025 requirements. Optional upgrade paths support GLP-compliant audit trails and FDA 21 CFR Part 11–aligned electronic signature functionality when paired with APKJ’s certified data acquisition software.
Software & Data Management
- Embedded controller firmware supports programmable test profiles (up to 99 segments), ramp/soak scheduling, and event-triggered alarms
- Real-time data export via USB or RS-232C to CSV or Excel-compatible formats; optional Ethernet connectivity for SCADA integration
- Optional APKJ LogView Pro software provides graphical trend analysis, deviation reporting, PDF report generation, and user-access-level management (admin/operator/viewer)
- All recorded temperature and RH data include timestamp, sensor ID, and measurement uncertainty metadata—fully compliant with ISO 17025 clause 7.7 on record retention and traceability
- Upgradeable firmware architecture ensures long-term compatibility with evolving regulatory expectations and internal QA workflows
Applications
The AP—HX chamber serves critical roles across aerospace component qualification, automotive electronics endurance validation, battery module thermal cycling, pharmaceutical packaging stability studies, and defense-system environmental survivability assessment. Its capacity to sustain simultaneous thermal and hygric stress makes it suitable for accelerated life testing (ALT), HALT/HASS pre-screening, and compliance verification against JEDEC JESD22-A110 (low temperature), JESD22-A118 (damp heat bias), and IPC-9701 (performance qualification of solder interconnections). Laboratories deploying this system routinely perform tests under controlled ambient conditions ranging from –40°C to +85°C and 10% to 98% RH—with optional sub-ambient dew point control enabling evaluation of condensation resistance in sealed enclosures.
FAQ
What is the standard internal humidity range, and can it be extended?
The default operational RH range is 20–95% RH at temperatures between 0°C and 85°C. Custom configurations support extended ranges including 5–95% RH, 10–95% RH, and 20–98% RH—subject to additional hardware integration and system recalibration.
Does the chamber support automated data recording and audit trail compliance?
Yes—when equipped with APKJ LogView Pro and configured with user authentication, electronic signatures, and immutable log files, the system satisfies FDA 21 CFR Part 11 and ISO/IEC 17025 data integrity requirements.
How is temperature and humidity uniformity validated?
Uniformity is verified per IEC 60068-3-5 using nine calibrated PT100 sensors positioned at specified locations within the working volume—measurements taken after 30 minutes of stabilization at setpoint.
What maintenance intervals are recommended for long-term reliability?
Routine inspection every 6 months includes refrigerant pressure verification, condensate drain line cleaning, filter replacement, and sensor calibration check; annual preventive maintenance includes full refrigeration loop performance assessment and controller firmware update.
Is on-site installation and operator training included with purchase?
Yes—APKJ provides turnkey commissioning including mechanical/electrical integration, functional performance verification, and hands-on operator training covering daily operation, profile programming, emergency response, and basic troubleshooting.
