Overview
The LabCompanion C-150-70-3 is a precision-engineered high-low temperature alternating test chamber designed for rigorous environmental stress screening (ESS), thermal cycling qualification, and reliability validation of electronic components, aerospace subsystems, automotive ECUs, and advanced materials. Built upon dual-refrigeration cascade cooling architecture with independent heating and cooling control loops, the chamber delivers stable, repeatable thermal profiles across its full operating range of −70 °C to +150 °C. Its 150-liter internal workspace accommodates medium-scale test specimens—including PCB assemblies, battery modules, optical sensors, and sealed enclosures—while maintaining uniformity ≤ ±1.5 °C and stability ≤ ±0.5 °C per hour under dynamic cycling conditions. The system operates on a closed-loop PID control strategy with real-time thermocouple feedback from multiple spatially distributed sensors, ensuring traceable thermal performance aligned with IEC 60068-2-14 (Test N: Change of Temperature) and MIL-STD-810H Method 503.5.
Key Features
- Industrial-grade stainless-steel inner chamber (SUS304) with seamless welding and anti-condensation insulation structure
- Dual-stage cascade refrigeration system using environmentally compliant R404A/R23 mixed refrigerant for rapid pull-down to −70 °C in ≤65 minutes (from 25 °C ambient)
- Pt100 Class A platinum resistance temperature sensors (RTDs) at 9 calibrated measurement points for spatial uniformity verification
- Programmable controller with 120-segment ramp-soak capability, supporting complex multi-step cycles including dwell, linear ramp, and rate-limited transitions
- Integrated safety interlocks: over-temperature cut-off, compressor high-pressure protection, door-open alarm, and phase failure detection
- RS485 Modbus RTU interface and optional Ethernet/IP connectivity for integration into centralized lab management systems
Sample Compatibility & Compliance
The C-150-70-3 accommodates standard test fixtures, DUT carriers, and non-vented sample racks up to 30 kg loading capacity. It supports both powered and unpowered device-under-test configurations, with provision for external signal feedthroughs (optional 6-channel electrical port kit). All operational parameters comply with international standards for environmental testing: IEC 60068-3-5 (guidance on thermal test methods), ASTM D3418 (thermal transition temperatures of polymers), and GB/T 2423.22 (Chinese national standard equivalent to IEC 60068-2-14). The chamber’s design and calibration documentation support GLP/GMP audit readiness, including traceable sensor calibration certificates (NIST-traceable reference standards) and full system validation reports (IQ/OQ/PQ templates available upon request).
Software & Data Management
The embedded controller firmware includes built-in data logging at user-selectable intervals (1–600 seconds), storing up to 10,000 hours of timestamped temperature history internally. Optional LabCompanion SmartView™ PC software enables remote monitoring, real-time graphing, automated report generation (PDF/CSV), and secure export for regulatory submission. Audit trail functionality records all operator actions—including profile uploads, setpoint modifications, and manual overrides—with time stamps and user IDs, satisfying FDA 21 CFR Part 11 requirements when deployed with Windows-based domain authentication. Data integrity is preserved via cyclic redundancy check (CRC) validation during transfer and encrypted local storage.
Applications
- Thermal cycling qualification of semiconductor packages (JEDEC JESD22-A104D)
- Accelerated life testing of lithium-ion battery cells under extreme temperature alternation
- Environmental stress screening (ESS) of avionics modules prior to flight certification
- Material compatibility assessment for seals, adhesives, and conformal coatings
- Validation of thermal management systems in electric vehicle power electronics
- Research-grade low-temperature behavior analysis of polymer composites and nanomaterials
FAQ
What is the typical temperature transition rate between −70 °C and +150 °C?
Standard ramp rate is 5 °C/min (average), configurable from 1 °C/min to 10 °C/min depending on load mass and thermal inertia.
Does the chamber support humidity control?
No—the C-150-70-3 is a dry-temperature-only platform. For combined temperature/humidity testing, refer to the LabCompanion TH-series chambers.
Is third-party calibration and certification available?
Yes—factory calibration includes as-found/as-left reports per ISO/IEC 17025 accredited procedures; on-site validation by CNAS-accredited partners can be arranged.
Can the controller interface with SCADA or MES systems?
Yes—Modbus RTU (RS485) is standard; optional OPC UA server module enables direct integration with Siemens Desigo, Rockwell FactoryTalk, or custom MES platforms.
What maintenance schedule is recommended for long-term reliability?
Compressor oil and filter replacement every 24 months; refrigerant leak check and sensor recalibration annually; full preventive maintenance service available under LabCompanion Platinum Care contract.
