Overview
The LabCompanion TC-400-10 High-Low Temperature Cycling Chamber is an engineered environmental test system designed for precise, repeatable thermal stress evaluation of materials, components, and electronic assemblies under controlled dynamic temperature conditions. Utilizing dual-refrigeration circuit architecture with cascade refrigeration technology and PID-controlled electric heating, the chamber delivers stable and programmable thermal profiles across a wide operational range—from cryogenic −70 °C to high-temperature +150 °C. Its design adheres to fundamental principles of heat transfer dynamics and thermodynamic equilibrium control, enabling both linear and non-linear ramping protocols essential for accelerated life testing (ALT), qualification per MIL-STD-810, and reliability screening in R&D and production QA environments.
Key Features
- Robust dual-stage refrigeration system with environmentally compliant R404A/R23 mixed refrigerant for reliable sub-zero performance down to −70 °C
- PID-based digital temperature controller with real-time monitoring, auto-tuning, and multi-segment programmability (up to 99 cycles, 999 steps)
- High-efficiency air circulation system featuring adjustable axial fans and optimized duct geometry to maintain ≤2.0 °C temperature uniformity across the full working volume
- Stainless steel 304 interior chamber with seamless welding, corrosion-resistant insulation, and reinforced structural frame for long-term dimensional stability
- Comprehensive safety architecture including over-temperature protection, compressor high/low pressure cut-off, phase sequence monitoring, and door interlock switch
- Modular electrical cabinet with industrial-grade PLC interface, optional RS485/RS232 communication ports, and analog signal outputs for integration into centralized lab monitoring systems
Sample Compatibility & Compliance
The TC-400-10 accommodates samples up to 800 mm (W) × 850 mm (D) × 600 mm (H), supporting standard test specimens, PCB assemblies, automotive ECUs, battery modules, optical sensors, and packaged semiconductor devices. It meets core requirements of IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and IEC 60068-2-14 (change of temperature) for environmental stress screening. The chamber’s thermal performance validation protocol follows ISO/IEC 17025-compliant calibration practices; temperature mapping reports are available upon request. All control firmware and data logging functions support audit-ready traceability aligned with GLP and GMP documentation standards.
Software & Data Management
The integrated LabCompanion TestSuite™ software (v3.2+) provides intuitive graphical programming of complex thermal cycles—including dwell, ramp, and step modes—with user-defined alarm thresholds and event-triggered logging. Raw temperature data is recorded at configurable intervals (1–60 sec) and exported in CSV or Excel-compatible formats. Optional Ethernet connectivity enables remote monitoring via secure HTTPS web interface or SCADA integration using Modbus TCP. Full data integrity is ensured through time-stamped records, operator ID tagging, and optional 21 CFR Part 11-compliant electronic signature modules for regulated industries.
Applications
- Thermal cycling qualification of aerospace avionics per DO-160 Section 4.5
- Reliability assessment of lithium-ion battery cells under extreme thermal gradients
- Material coefficient of thermal expansion (CTE) characterization for polymer composites and solder joints
- Pre-conditioning of optical coatings and MEMS devices prior to laser damage threshold testing
- Environmental stress screening (ESS) of automotive ADAS modules in accordance with AEC-Q200
- Accelerated aging studies of encapsulants, conformal coatings, and flexible printed circuits
FAQ
What is the typical calibration interval recommended for the TC-400-10?
Annual calibration against NIST-traceable reference standards is recommended; internal sensor verification can be performed quarterly using certified dry-block calibrators.
Can the chamber be configured for humidity control?
No—the TC-400-10 is a dry-temperature-only cycling system. For combined temperature/humidity testing, consider the LabCompanion TH-400 series.
Is external exhaust ducting required for safe operation?
Not under standard operating conditions; however, ducting is advised when conducting extended high-temperature tests (>120 °C) in confined rooms to manage ambient heat load.
Does the system support third-party scripting interfaces such as Python or LabVIEW?
Yes—via ASCII command protocol over RS232/RS485 or Modbus TCP, with documented register maps and example drivers provided in the technical manual.
What documentation is supplied with the unit?
Factory calibration report, ISO 9001-certified manufacturing compliance certificate, CE Declaration of Conformity, user manual, maintenance guide, and software installation media.
