LabCompanion TC-180 Temperature Cycling Chamber

Overview

The LabCompanion TC-180 Temperature Cycling Chamber is an engineered environmental test system designed for precise, repeatable thermal stress evaluation of electronic components, automotive modules, aerospace subsystems, and advanced materials under controlled temperature extremes. It operates on a dual-refrigeration architecture with independent heating and cooling circuits, enabling rapid, programmable transitions between −70 °C and +150 °C. Unlike basic thermal ovens or static chambers, the TC-180 supports both linear and non-linear temperature ramp profiles—critical for simulating real-world thermal shock, burn-in, and HALT/HASS protocols. Its chamber core is constructed from SUS304 stainless steel with multi-layer insulated walls and a forced-air convection system ensuring uniform thermal distribution (±0.5 °C stability per GB/T 5170.2–2008). The unit meets fundamental requirements for laboratory-grade environmental simulation in R&D, quality assurance, and reliability engineering workflows.

Key Features

• Dual-stage refrigeration system with cascade compressor design for extended low-temperature capability down to −70 °C
• Programmable ramp rates from 5 °C/min to 25 °C/min, selectable as linear or custom non-linear profiles via touchscreen controller
• Optional liquid nitrogen (LN₂) assist module available to achieve cooling rates up to 30 °C/min—enabling accelerated thermal shock testing per MIL-STD-810G Method 503.5
• High-precision PID-controlled heating system with redundant over-temperature protection (hardware cut-off at +160 °C)
• Stainless steel interior (SUS304) with rounded corners and removable shelves for ease of cleaning and sample accessibility
• Integrated data logging with timestamped temperature (and humidity, if configured) records stored internally and exportable via USB

Sample Compatibility & Compliance

The TC-180 accommodates standard test specimens up to 600 mm (W) × 600 mm (H) × 500 mm (D), supporting PCB assemblies, IC packages, battery cells, polymer composites, and small mechanical subassemblies. Its thermal performance is validated per GB/T 5170.2–2008 (temperature) and GB/T 5170.5–2008 (humidity, when equipped). While not inherently certified to IEC 60068-2 or ASTM E1512, the chamber’s control accuracy, repeatability, and documented calibration traceability support alignment with ISO/IEC 17025-compliant lab environments. Users performing GLP or GMP-regulated testing may configure audit trails and user-level access controls through optional software integration.

Software & Data Management

The embedded 7-inch color touchscreen interface provides intuitive profile programming, real-time monitoring, alarm management, and event logging. Standard firmware supports up to 100 programmable test cycles with 99 segments per cycle. For enhanced traceability, optional PC-based LabCompanion TestSuite software enables remote monitoring, automated report generation (PDF/CSV), and compliance-ready documentation—including calibration history, operator ID, and deviation alerts. When integrated with enterprise LIMS or MES platforms, the TC-180 can transmit live sensor data via Modbus TCP or RS485, facilitating centralized environmental test data aggregation and 21 CFR Part 11–compliant electronic signatures (with appropriate validation package).

Applications

• Thermal cycling qualification of semiconductor devices per JEDEC JESD22-A104
• Pre-conditioning of lithium-ion batteries prior to safety testing (UN 38.3, IEC 62133)
• Material coefficient of thermal expansion (CTE) characterization via dimensional metrology during controlled ramps
• Reliability screening of automotive ECUs under ISO 16750-4 temperature profiles
• Accelerated aging studies for adhesives, encapsulants, and conformal coatings
• Validation of packaging integrity for medical devices exposed to cold-chain logistics conditions

FAQ

What is the standard temperature calibration interval recommended for the TC-180?
LabCompanion recommends annual calibration using NIST-traceable reference sensors; internal verification checks should be performed before each critical test run.
Can the TC-180 operate continuously at −70 °C for extended periods?
Yes—the chamber is rated for continuous operation across its full temperature range, including sustained hold at −70 °C, provided ambient room temperature remains ≤+30 °C and relative humidity ≤80% RH.
Is humidity control included in the TC-180-10 model?
No—the TC-180-10 is a dry-temperature-only configuration. Humidity capability requires the TH-series variant (e.g., TH-180) with steam generator and dehumidification subsystem.
Does the unit support external trigger inputs for synchronized testing?
Yes—digital I/O ports (2-channel input, 2-channel output) are standard for hardware-level synchronization with power supplies, DAQ systems, or functional testers.
What maintenance is required to sustain specified temperature deviation (±2.0 °C)?
Routine maintenance includes quarterly condenser coil cleaning, annual refrigerant pressure verification, and biannual verification of fan motor performance and door gasket integrity.
