Overview
The Aipu Technology AP-KF-15C Walk-in Environmental Test Chamber is an industrial-grade, fully customizable walk-in environmental test system engineered for long-term, high-reliability thermal and humidity conditioning of large-scale components, assemblies, and finished products. Designed in accordance with ISO 16750-4 (Road vehicles — Environmental conditions and testing for electrical and electronic equipment), IEC 60068-2 series (Environmental testing — Part 2: Tests), and aligned with GLP-compliant laboratory infrastructure requirements, the AP-KF-15C employs a Balanced Temperature and Humidity Control (BTHC) architecture. This closed-loop control strategy dynamically regulates heating, humidification, and refrigeration outputs via PID-driven SSR modulation—ensuring that thermal/hygrometric input precisely offsets chamber load losses. The result is stable, repeatable environmental profiles across extended dwell cycles, critical for qualification testing in automotive, aerospace, energy storage, and electronics manufacturing.
Key Features
- Modular stainless steel (SUS304) interior construction with seamless welding and electropolished finish—resistant to corrosion, condensation accumulation, and microbial growth under high-humidity operation.
- Exterior cladding in pre-painted color-coated steel panels—providing structural rigidity, thermal insulation integrity, and cleanroom-compatible aesthetics.
- Dual-stage refrigeration system utilizing imported European/American compressors (R404A/R23 cascade configuration) optimized for wide-range temperature stability; enables reliable operation from 0 °C to +85 °C with minimal thermal overshoot.
- Horizontal air distribution with vertical heat exchange circulation—achieved via low-noise, multi-blade stainless steel centrifugal fans—ensures uniform airflow and eliminates thermal stratification or dead zones per ASTM E145-22 Annex A1.
- High-resolution 7-inch LCD touchscreen controller (SUNTOW brand) with real-time data logging, programmable ramp-soak profiles, and built-in alarm management—including nine predefined fault codes with automatic power cutoff and on-screen diagnostic guidance.
- Analog output interface (4–20 mA or 0–10 V DC) for external temperature/humidity recording systems—supports traceable validation per FDA 21 CFR Part 11 when paired with compliant data acquisition software.
Sample Compatibility & Compliance
The AP-KF-15C accommodates oversized test specimens—including battery modules, server racks, HVAC units, and vehicle ECUs—with fully customizable internal dimensions (depth × width × height). Its structural modularity allows field expansion or relocation without system decommissioning. All materials comply with RoHS Directive 2011/65/EU. Refrigerant selection (R404A primary stage, R23 secondary stage) conforms to EU F-Gas Regulation (No 517/2014) phase-down schedules. Electrical safety meets IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. Optional IQ/OQ documentation packages are available to support GMP, ISO 9001, and AS9100 audit readiness.
Software & Data Management
The integrated controller supports Ethernet and RS-485 communication protocols (Modbus RTU), enabling bidirectional integration with LabVIEW, MATLAB, or enterprise MES platforms. Users may design, upload, and execute multi-step environmental profiles remotely via PC-based companion software. All operational parameters—including setpoints, actual readings, alarm events, and system status—are timestamped and stored locally (≥100,000 data points) with optional USB export. Audit trail functionality includes user login logs, parameter change history, and firmware version tracking—meeting ALCOA+ principles for data integrity in regulated environments.
Applications
- Accelerated life testing of lithium-ion battery packs under combined thermal stress and humidity cycling.
- Pre-conditioning of photovoltaic inverters prior to IP65/IP67 ingress protection verification.
- Stability assessment of pharmaceutical packaging materials per ICH Q1A(R2) guidelines.
- Thermal soak validation for avionics line-replaceable units (LRUs) in accordance with DO-160G Section 4.
- Environmental screening of military-grade connectors and cable harnesses per MIL-STD-810H Method 502.7.
FAQ
What is the standard lead time for a custom-configured AP-KF-15C chamber?
Typical delivery is 8–12 weeks after final dimensional approval and deposit confirmation—subject to compressor availability and panel fabrication scheduling.
Can the chamber be validated for IQ/OQ/PQ under GxP requirements?
Yes—Aipu provides optional vendor-supported qualification protocols, including sensor mapping reports, temperature/humidity uniformity studies, and deviation handling SOPs.
Is remote monitoring supported without third-party middleware?
Yes—the native controller includes embedded web server capability for real-time parameter viewing and basic control via standard HTTP/HTTPS browsers.
What maintenance intervals are recommended for the dual-stage refrigeration system?
Compressor oil analysis and filter-drier replacement every 24 months; annual calibration of Pt100 sensors and verification of dew point accuracy using NIST-traceable hygrometers.
Does the system support humidity control below 20% RH?
Standard configuration maintains 20–98% RH at 25 °C; sub-20% RH operation requires optional desiccant dehumidification module (not included in base AP-KF-15C).
