Overview
The Walk-in High-Low Temperature Environmental Test Chamber is a large-volume, floor-standing climatic test system engineered for precise thermal stress evaluation of industrial components, electronic assemblies, automotive modules, and aerospace subsystems under controlled extreme temperature conditions. Based on forced-air convection with dual-stage refrigeration and high-efficiency electric heating, the chamber maintains stable and uniform thermal profiles across its internal workspace—typically ranging from −70 °C to +180 °C (configurable per IEC 60068-2-1, IEC 60068-2-2, and MIL-STD-810G environmental test protocols). Its walk-in architecture enables full-scale testing of bulky or integrated systems—including powered devices—without disassembly, supporting real-time functional monitoring during thermal cycling. The chamber’s structural integrity, thermal insulation performance, and air distribution design comply with ISO 17025-accredited calibration traceability requirements for laboratory-grade environmental simulation.
Key Features
- Smooth-radius exterior housing with matte-finish stainless steel cladding and ergonomic flush-mounted handles for safe, tool-free access
- Hermetically sealed double-wall construction with high-density polyurethane foam insulation (≥150 mm thickness) and vacuum-sealed door gaskets to minimize thermal leakage
- Low-noise, high-torque axial circulation motor coupled with optimized baffle-guided airflow for ≥90% temperature uniformity (±1.5 °C at steady state, per GB/T 5170.2–2017)
- Integrated anti-vibration mounting pads compliant with ISO 10816-3 vibration severity thresholds for Class II machinery
- Powered-through capability: 3-phase 380 V/50 Hz (or configurable 480 V/60 Hz) electrical feedthroughs with IP54-rated cable glands and load-rated terminal blocks
- High-intensity Philips LED viewing window lighting with embedded resistive defogging film (operational up to 150 °C) for uninterrupted visual inspection
- Multi-layer safety architecture including over-temperature cut-off, compressor high-pressure shutdown, phase failure protection, and door interlock circuitry
Sample Compatibility & Compliance
This chamber accommodates samples up to 2,000 mm (W) × 2,000 mm (D) × 2,200 mm (H), with customizable interior shelving and optional humidity control add-ons (for combined temp/humidity variants). It meets or exceeds core verification standards for environmental test equipment, including GB/T 5170.2–2017 (Temperature Test Equipment), GB 10592–2008 (Specifications for High/Low Temperature Chambers), and IEC 60068-3-5 (Methods for Determining Changes in Temperature). Validation documentation supports GLP-compliant test reporting and aligns with ASTM E145–22 (Standard Specification for Gravity-Convection and Forced-Ventilation Ovens), as well as MIL-STD-810G Method 501.7 (High Temperature) and Method 502.7 (Low Temperature). Calibration certificates are issued per ISO/IEC 17025 requirements when paired with accredited third-party service providers.
Software & Data Management
The chamber integrates a programmable 10.1″ touchscreen controller with embedded RS485/Modbus RTU and optional Ethernet (TCP/IP) interfaces. It supports multi-step thermal profiles (up to 99 segments), ramp-soak-hold sequences, and real-time data logging at user-defined intervals (minimum 1 s resolution). All operational events—including setpoint changes, alarm triggers, and power interruptions—are recorded with timestamped audit trails compliant with FDA 21 CFR Part 11 Annex 11 principles. Exportable CSV logs include chamber ambient, sensor feedback, and actuator status channels. Optional PC-based software (Windows/Linux compatible) enables remote supervision, automated report generation (PDF/Excel), and integration into enterprise LIMS or MES platforms via OPC UA.
Applications
- Thermal aging and accelerated life testing of PCBAs, battery packs, and EV power electronics
- Qualification of avionics enclosures per DO-160 Section 4 (Temperature Variation)
- Stress screening of military-grade connectors and ruggedized housings (MIL-STD-883 Method 1010)
- Material coefficient-of-thermal-expansion (CTE) characterization under controlled gradients
- Pre-compliance validation for IEC 60950-1, IEC 62368-1, and UL 60950 safety certifications
- Environmental stress screening (ESS) and HALT/HASS protocol execution in reliability labs
FAQ
What is the standard temperature range for this walk-in chamber?
Standard operation spans −70 °C to +180 °C; extended low-temperature options (−80 °C) and high-temperature upgrades (+200 °C) are available upon request.
Does the chamber support real-time power supply to DUTs during testing?
Yes—three-phase 380 V/50 Hz feedthroughs with overload protection enable continuous powered operation of devices under test.
Is calibration traceability provided with delivery?
A factory-as-built temperature uniformity and stability report is included; NIST-traceable calibration certificates require separate scheduling with an ISO/IEC 17025-accredited provider.
Can the controller be validated for 21 CFR Part 11 compliance?
The embedded controller supports electronic signatures, audit trail export, and role-based access control—fully configurable for Part 11 readiness when deployed with approved IT infrastructure.
What installation prerequisites must be met prior to commissioning?
A dedicated 3-phase power supply (with proper grounding), minimum 1.5 m clearance around all sides for heat dissipation, and a level, reinforced concrete floor capable of supporting ≥1,200 kg static load are mandatory.
