Overview
The LabCompanion WPH-12000 is a fully engineered, modular walk-in environmental test chamber designed for large-scale, long-duration stability, stress, and qualification testing of industrial components, aerospace subsystems, automotive assemblies, and electronic enclosures. Based on dual-refrigeration cascade systems with PID-controlled electric heating and steam-based humidification, the WPH-12000 operates on fundamental thermodynamic principles—precisely regulating sensible and latent heat exchange to maintain stable or dynamically cycled temperature and humidity profiles across its 12.5 m³ internal volume. Its structural architecture features 100 mm thick polyurethane-insulated panels (density ≥42 kg/m³, thermal conductivity ≤0.022 W/m·K), stainless steel interior cladding (SUS304), and an external galvanized steel skin with powder-coated finish—ensuring long-term integrity under repeated thermal cycling and high-humidity exposure. Unlike benchtop chambers, the WPH-12000 supports full-system-level validation per MIL-STD-810H, RTCA DO-160G, and IEC 60529 IPX4/IPX5 protocols where spatial uniformity and volumetric load capacity are critical.
Key Features
- Modular panel construction with tongue-and-groove interlocking joints and silicone-sealed seams—enabling field assembly, future expansion, and maintenance access without structural compromise
- Dual-stage refrigeration system using environmentally compliant R404A/R23 cascade configuration for reliable operation down to -60°C
- Steam-type humidification system with deionized water feed, stainless steel boiler, and condensate recovery loop—minimizing mineral buildup and ensuring repeatable RH control from 30% to 95% RH
- 7-inch color touchscreen HMI with embedded real-time data logging (1 Hz sampling), user-defined profile programming (up to 99 segments), and alarm history with timestamped event codes
- Redundant safety architecture including independent high-limit controllers, door interlock switches, refrigerant pressure cut-offs, and over-temperature/over-humidity shutdown circuits
- Optional integrated data acquisition interface (RS485/Modbus RTU, Ethernet TCP/IP) for SCADA integration and centralized lab monitoring
Sample Compatibility & Compliance
The WPH-12000 accommodates full-size prototypes—including EV battery packs (up to 1.5 m tall), avionics racks, medical imaging consoles, and HVAC duct assemblies—without requiring disassembly. Its interior layout permits unobstructed airflow via rear-mounted centrifugal blowers and perforated floor plenums, meeting ASTM D4332 requirements for air velocity distribution (<0.5 m/s at sample surface). All control firmware and calibration documentation comply with GLP and GMP traceability standards; optional IQ/OQ documentation packages support FDA 21 CFR Part 11 compliance for regulated industries. The chamber has been verified against ISO 2231 Annex A (environmental stress screening) and IEC 60068-2-30 (damp heat, cyclic) test methods, with temperature and humidity uniformity validated per IEC 60068-3-5 using NIST-traceable Class A sensors at nine predefined spatial locations.
Software & Data Management
LabCompanion’s proprietary WinTest Pro software (Windows-based, license-free) enables remote chamber supervision, multi-user role management (admin/operator/auditor), and automated report generation in PDF/CSV formats. All setpoint changes, alarm triggers, and calibration events are time-stamped and digitally signed—supporting audit-ready electronic records per 21 CFR Part 11 when paired with domain-authenticated login and biometric or smart-card authentication (optional). Data export includes raw sensor logs (temperature, humidity, dew point, compressor status), statistical summaries (mean, min/max, standard deviation per cycle), and deviation trend charts aligned to test plan milestones. Historical data is stored locally on an industrial-grade SSD and mirrored to network-attached storage via configurable FTP/SFTP upload schedules.
Applications
- Automotive: Battery thermal runaway propagation studies, ECU cold-start validation (-40°C), and cabin module humidity aging per SAE J2412
- Aerospace: Avionics box qualification per RTCA DO-160G Section 4 (temperature), Section 5 (humidity), and Section 10 (explosive atmosphere simulation)
- Electronics: Accelerated life testing of PCBAs under combined temperature/humidity stress (e.g., JEDEC JESD22-A101, JESD22-A108)
- Energy Storage: Cycle-life evaluation of lithium-ion modules under dynamic charge/discharge conditions synchronized with ambient chamber profiles
- Pharmaceutical: Stability chamber mapping for ICH Q1A(R3) long-term and accelerated storage condition verification (25°C/60% RH, 30°C/65% RH, 40°C/75% RH)
FAQ
What is the maximum allowable thermal mass load for achieving specified temperature ramp rates?
For guaranteed 3°C/min heating (non-linear load), total thermal mass should not exceed 1,200 kg with average specific heat ~0.9 kJ/kg·K. Actual ramp performance is load-dependent and requires pre-test thermal inertia characterization.
Can the WPH-12000 be configured for low-pressure operation (e.g., altitude simulation)?
Yes—optional vacuum pump integration and reinforced chamber sealing enable operation down to 10 kPa absolute pressure, compliant with IEC 60068-2-17 (altitude testing) and MIL-STD-810H Method 500.6.
Is third-party calibration certification available upon delivery?
Yes—NIST-traceable calibration certificates (temperature/humidity) issued by CNAS-accredited labs are available as an add-on service, including as-found/as-left data and uncertainty budgets per ISO/IEC 17025.
How is condensate managed during high-humidity operation?
A dedicated condensate collection sump with level sensor and automatic drain pump routes condensed moisture to an external floor drain, preventing internal pooling and microbial growth.
Does the system support automated pass/fail evaluation against test specifications?
Yes—WinTest Pro allows defining tolerance bands per test segment; deviations trigger immediate alerts, log entries, and optional email/SMS notifications via SMTP or GSM gateway.
