LabCompanion WP-9000 Walk-in Environmental Test Chamber

Overview

The LabCompanion WP-9000 is a modular, walk-in environmental test chamber engineered for long-duration thermal stress testing of large-scale industrial components, aerospace subassemblies, automotive ECUs, and energy storage systems. Unlike benchtop or reach-in chambers, the WP-9000 employs a robust insulated enclosure architecture with 100 mm thick high-density polyurethane (PU) panels (floor) and 75 mm panels (walls/ceiling), enabling stable thermal performance across extreme operating ranges. Its core thermal control system utilizes a dual-stage cascade refrigeration circuit—optimized for rapid pull-down to −70 °C—combined with precision PID-controlled electric heating elements. The chamber operates exclusively in dry temperature mode (no humidity generation or control), making it suitable for applications requiring strict dew-point management, oxidation-sensitive material aging, or thermal cycling under inert atmospheres. All structural joints are continuously welded or gasket-sealed to minimize thermal leakage, and internal airflow is engineered via a top-mounted centrifugal blower with adjustable multi-directional ducting to ensure uniform temperature distribution per IEC 60068-3-5 requirements.

Key Features

• Modular prefabricated steel frame with PU-insulated sandwich panels (100 mm floor / 75 mm walls & ceiling) for structural integrity and thermal efficiency
• Dual-stage cascade refrigeration system with environmentally compliant R404A/R23 refrigerant blend, enabling reliable operation down to −70 °C
• Precision digital temperature controller with 0.1 °C resolution, ±0.5 °C control accuracy, and programmable ramp-soak profiles
• Uniform internal airflow design validated to maintain ≤ ±2 °C temperature deviation across full working volume (1970 × 1970 × 2100 mm)
• Integrated safety systems: over-temperature cut-off, refrigerant pressure monitoring, door interlock, and emergency stop circuitry
• Front-access service corridor for maintenance of compressors, condensers, and electrical cabinets without disrupting chamber integrity
• Optional upgrades include nitrogen purge ports, RS485 Modbus RTU interface, and external data logging via Ethernet/IP

Sample Compatibility & Compliance

The WP-9000 accommodates large-format test specimens—including battery modules (up to 1.5 m tall), avionics racks, and HVAC duct assemblies—within its 8.1 m³ usable volume. Its dry-temperature-only configuration eliminates condensation risk during low-temperature holds, supporting ASTM D3574 (foam compression set), MIL-STD-810H Method 502.7 (low-temperature storage), and SAE J2380 (EV battery thermal shock). The chamber meets national standards GB/T 2423.1 (cold testing) and GB/T 2423.2 (dry heat testing), and its mechanical construction adheres to ISO 14644-1 Class 8 cleanroom-compatible sealing practices. While not certified for GLP/GMP environments out-of-the-box, the system supports audit-ready documentation packages—including calibration certificates traceable to NIM (National Institute of Metrology, China) and IQ/OQ protocol templates—for regulated validation workflows.

Software & Data Management

The embedded controller includes a 7-inch TFT touchscreen HMI with on-device profile programming, real-time trend display, and event log storage (≥10,000 entries). Optional LabCompanion ChamberLink™ software enables remote monitoring, multi-chamber synchronization, and automated report generation (PDF/CSV) compliant with FDA 21 CFR Part 11 requirements when paired with user-defined electronic signatures and audit trail activation. All temperature data are timestamped with UTC sync capability and support configurable alarm notifications via email/SMS gateways. Raw sensor outputs (PT100 class A) are sampled at 1 Hz and archived with checksum verification to prevent data corruption.

Applications

• Thermal aging of lithium-ion battery packs under extended −40 °C to +85 °C cycling protocols
• Pre-conditioning of composite aircraft fuselage sections prior to structural load testing
• Validation of military-grade electronics per MIL-STD-810G temperature shock and storage profiles
• Stability assessment of pharmaceutical packaging materials under accelerated dry-heat conditions
• Environmental screening of solar inverter enclosures for desert deployment scenarios
• Calibration lab reference environment for large-scale metrology fixtures and CMM bases

FAQ

Is humidity control available on the WP-9000 model?
No—the WP series is strictly a dry-temperature chamber. For combined temperature/humidity testing, specify the WPH series.
Can the chamber be customized for non-standard dimensions or temperature ranges?
Yes. LabCompanion offers engineering-led custom design services for non-standard volumes, extended ranges (e.g., −80 °C), or integration with inert gas purge systems.
What is the typical lead time for delivery and commissioning?
Standard WP-9000 units ship within 12–14 weeks from order confirmation; on-site installation and SAT (Site Acceptance Testing) require an additional 5–7 business days.
Does the system include factory calibration documentation?
Yes—each unit ships with a NIST-traceable calibration certificate for all primary PT100 sensors and controller inputs, valid for 12 months.
Are spare parts and technical support available outside China?
LabCompanion maintains authorized service partners in Germany, USA, South Korea, and Singapore, with 48-hour remote diagnostics and 5-day on-site response SLAs for critical issues.
