Overview
The Electromagnetic Walk-In Environmental Chamber for Temperature and Humidity Control is a precision-engineered, large-volume climatic test system designed for rigorous reliability validation of industrial components, electronics, automotive modules, and packaging materials under dynamically controlled thermal and hygrothermal stress. Unlike benchtop chambers, this walk-in configuration enables full-system testing—accommodating assembled units, battery packs, control cabinets, or multi-part assemblies—with uniform environmental exposure across the entire internal volume. The chamber employs electromagnetic actuation in its air-handling system to ensure precise modulation of airflow velocity and direction, minimizing thermal stratification and enabling high-fidelity replication of real-world environmental profiles—including rapid temperature transitions (e.g., -40 °C ↔ +85 °C within ≤60 min), sustained high-humidity holds, and cyclic humidity ramping per IEC 60068-2-78. Its structural integrity, double-wall insulated construction, and hermetic sealing support long-duration tests compliant with MIL-STD-810H Method 507.5 and JEDEC JESD22-A110.
Key Features
- Electromagnetically driven variable-speed centrifugal blower assembly for optimized air distribution and reduced mechanical wear versus conventional belt-driven systems
- Microprocessor-based PID controller with SSR output and programmable timer—supporting up to 99 segments per profile and 999 cycles per test sequence
- LCD touch interface with intuitive dialog-style navigation, multilingual support (English, German, Japanese), and real-time graphical display of setpoints and actual values
- Dual-sensor humidity measurement system (capacitive polymer sensor + optional chilled-mirror dew point reference) for traceable RH accuracy ±2 % RH (20–80 % RH range)
- Integrated safety architecture: independent over-temperature cutoff, high-humidity shutoff, refrigerant pressure monitoring, door interlock, and automatic power recovery after outage
- Standard 50 mm diameter cable port (left-side mounted), dual adjustable sample racks, interior LED lighting, and tempered observation window with anti-fog coating
Sample Compatibility & Compliance
This chamber accommodates heterogeneous test specimens—including enclosures rated IP54 or higher, PCB assemblies, lithium-ion battery modules, medical device housings, and aerospace subassemblies—without requiring disassembly. Its internal dimensions (1000 × 1600 × 1000 mm W×H×D) permit static or quasi-dynamic loading configurations. All operational modes comply with internationally recognized environmental testing standards, including but not limited to: IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), IEC 60068-2-78 (damp heat, cyclic), ISO 16750-4 (road vehicles), ASTM D4332 (conditioning of plastics), and ASTM D2244 (colorimetric stability). Optional calibration certificates are traceable to NIST or UKAS-accredited laboratories, supporting GLP/GMP audit readiness.
Software & Data Management
The embedded controller supports RS-485 Modbus RTU and optional Ethernet TCP/IP communication protocols for integration into centralized test management platforms (e.g., TestStand, LabVIEW, or custom MES interfaces). With optional data logging hardware or PC-based software, users can acquire timestamped temperature/humidity readings at user-defined intervals (1 s to 60 min), generate CSV/Excel reports, and export trend plots compatible with FDA 21 CFR Part 11 requirements when configured with electronic signature and audit trail functionality. Firmware updates are performed via USB memory stick, ensuring long-term maintainability without vendor dependency.
Applications
- Accelerated life testing of EV battery thermal management systems under combined low-T/high-RH stress
- Validation of enclosure sealing integrity per IP67/IP68 during extended 85 °C/85 % RH exposure
- Pre-compliance screening of automotive ECUs against ISO 16750-4 temperature cycling and humidity soak profiles
- Stability assessment of pharmaceutical packaging materials under ICH Q1A(R3) long-term and accelerated storage conditions
- Qualification of avionics cooling ducts under MIL-STD-810H Method 507.5 (humidity) and Method 502.6 (temperature shock)
FAQ
What is the standard temperature and humidity uniformity specification across the working volume?
Per IEC 60068-3-5, typical spatial uniformity is ±1.5 °C (temperature) and ±3 % RH (humidity) at steady state, verified at nine predefined locations using calibrated reference sensors.
Can the chamber be configured for non-standard humidity ranges such as 5–98 % RH?
Yes—custom humidity transducers, enhanced steam generator capacity, and modified condensate management are available as factory-installed options upon request.
Is remote monitoring and alarm notification supported out-of-the-box?
Basic remote status polling is enabled via Modbus; email/SMS alerts require integration with third-party SCADA or IoT gateway hardware (e.g., Siemens Desigo CC or Ignition SCADA).
Does the system include validation documentation for GxP-regulated environments?
IQ/OQ documentation templates are provided; full qualification (including PQ) must be executed on-site by the end user or an accredited third-party service provider per ISO 13485 or 21 CFR Part 11 guidelines.
