LabCompanion CTL-180W Thermal Shock Test Chamber

Overview

The LabCompanion CTL-180W Thermal Shock Test Chamber is an industrial-grade, dual-zone, air-to-air thermal shock system engineered for accelerated reliability validation of electronic components, aerospace hardware, automotive modules, and high-performance polymers under extreme temperature transition stress. It operates on the principle of rapid, controlled transfer between independently regulated high-temperature and low-temperature chambers—enabling precise simulation of real-world thermal cycling events such as solder joint fatigue, seal integrity failure, and interfacial delamination. Unlike single-chamber ramp-based systems, the CTL-180W employs a mechanical lift-and-transfer basket mechanism with ≤5 s dwell-free movement, ensuring reproducible shock profiles compliant with MIL-STD-810H Method 503.7 and IEC 60068-2-14. Its 180 L working volume accommodates full-size PCB assemblies, sensor housings, and multi-layer packaging configurations without compromising thermal uniformity across the test zone.

Key Features

• Dual independent chamber architecture: Separated high-temperature (+60 °C to +200 °C) and low-temperature (0 °C to −70 °C) zones with zero cross-contamination risk;
• High-fidelity thermal control: Armored Pt100 RTD sensors coupled with Siemens S7-1200 PLC deliver ±2 °C temperature stability and ≤±0.5 °C uniformity (per GB/T 5170.2–2017);
• Rapid thermal transition: ≤5 s basket transfer time and ≤5 min temperature recovery post-transfer—critical for replicating field-relevant shock durations;
• Robust thermal insulation: 150 mm thick non-hazardous glass fiber matrix minimizes heat leakage and ensures energy efficiency during prolonged cycling;
• Modular refrigeration design: Optional air-cooled (A) or water-cooled (W) configuration supports integration into lab HVAC constraints or cleanroom utility infrastructure;
• Comprehensive data governance: Embedded PlatinumV1.0 software logs timestamped CSV files (via USB) containing setpoints, chamber readings, alarm history, and cycle counters—structured for traceability in GLP/GMP environments;
• Secure network interface: RJ45 port enables optional deployment of PlatinumV1.0 PC monitoring suite, supporting concurrent access from up to five workstations and centralized management of up to 32 chambers.

Sample Compatibility & Compliance

The CTL-180W accommodates test specimens up to 600 × 660 × 450 mm (W×H×D), including populated circuit boards, hermetically sealed MEMS devices, battery packs, and composite structural coupons. Its internal 304 stainless steel chamber resists corrosion from condensate, flux residues, and halogenated outgassing—essential for qualification testing per IPC-J-STD-001 and JEDEC JESD22-A104. The system meets military and civil standards including GJB 150.3 (high temperature), GJB 150.4 (low temperature), and GJB 150.5 (temperature shock), as well as IEC 60068-2-14, GB/T 2423.1 (cold), and GB/T 2423.2 (dry heat). All controller firmware and data logging routines are designed to support audit-ready documentation required under ISO/IEC 17025 and FDA 21 CFR Part 11 when used with validated software configurations.

Software & Data Management

Control and monitoring are executed via the embedded PlatinumV1.0 platform—a deterministic real-time environment built on Siemens TIA Portal architecture. The 7-inch capacitive touchscreen provides intuitive navigation through multi-level test programs, parameter presets, and real-time trend visualization. All operational data—including cycle count, dwell duration, overshoot magnitude, and alarm timestamps—are logged in comma-separated value (CSV) format to USB storage. Files retain ISO 8601 timestamps and include metadata fields for operator ID, test protocol version, and chamber serial number. While USB ports do not support hot-plug operation, continuous connection ensures uninterrupted logging integrity. For enterprise deployment, the optional PlatinumV1.0 PC Monitoring Suite adds remote diagnostics, automated report generation (PDF/Excel), and database archiving compatible with LIMS integration. Audit trails record all user actions—including profile edits, manual overrides, and calibration interventions—with immutable timestamps.

Applications

• Qualification of avionics modules per DO-160 Section 4 (Temperature Shock);
• Failure mode analysis of power semiconductor packages under repeated thermal cycling;
• Validation of conformal coating adhesion and die-attach integrity in automotive ECUs;
• Accelerated life testing of lithium-ion battery cells at boundary conditions (−40 °C to +150 °C);
• Material compatibility screening for medical device housings exposed to sterilization and cold-chain transport;
• Reliability assessment of optical sensor assemblies subject to diurnal environmental extremes.

FAQ

What is the maximum thermal shock range achievable with the CTL-180W?
The standard CTL-series configuration supports a shock range of −40 °C to +150 °C. Custom variants (CTU/CTS) extend the low-end to −55 °C and −65 °C respectively, while maintaining the +150 °C upper limit.

Does the system comply with FDA 21 CFR Part 11 requirements?
Yes—when operated with the validated PlatinumV1.0 PC Monitoring Suite and appropriate user access controls, the system supports electronic signatures, audit trail retention, and data integrity safeguards aligned with Part 11 Annex 11 expectations.

Can the chamber be integrated into an existing facility SCADA network?
Absolutely. The native Modbus TCP protocol over RJ45 enables seamless integration with third-party SCADA platforms, DCS systems, and MES infrastructure without proprietary gateways.

Is calibration certification included with delivery?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), covering temperature uniformity, stability, and sensor accuracy across the full operational envelope.

What maintenance intervals are recommended for long-term reliability?
Compressor oil and refrigerant analysis every 24 months; filter-drier replacement every 18 months; annual verification of Pt100 sensor drift and PLC timing accuracy per ISO/IEC 17025 procedures.
