LabCompanion TC-150-5 High-Low Temperature Environmental Test Chamber

Overview

The LabCompanion TC-150-5 High-Low Temperature Environmental Test Chamber is an engineered solution for precise, repeatable thermal stress testing across industrial quality control, electronics reliability validation, automotive component qualification, and materials science research. Built upon a dual-stage compressor refrigeration system with PID-controlled heating and cooling circuits, the chamber delivers stable, programmable temperature profiles within a working range of −70 °C to +150 °C. Its design adheres to fundamental thermodynamic principles governing convective heat transfer and thermal equilibrium in enclosed volumes, ensuring consistent thermal loading on test specimens under controlled ambient conditions. The chamber is intended for non-hazardous environments and complies with general-purpose safety standards for laboratory and production floor deployment (IEC 61000-4 series immunity, IEC 60950-1 electrical safety).

Key Features

• Robust stainless-steel inner chamber (SUS304) with seamless welding and electrostatically applied epoxy-coated outer casing for corrosion resistance and long-term structural integrity.
• High-efficiency hermetic compressors paired with copper-aluminum finned evaporators and condensers, enabling rapid thermal response: typical heating and cooling rates of 5.0 °C/min from ambient to target setpoints.
• Dual independent PID controllers—one for heating, one for cooling—minimize overshoot and stabilize temperature at ±0.5 °C fluctuation (measured over 30 min at steady state), with spatial uniformity maintained within ±2.0 °C across the full 150 L workspace (500 × 600 × 500 mm).
• Intuitive 7-inch color touchscreen HMI with multi-segment programmable ramp-soak profiles, real-time trend logging, and password-protected parameter access levels for operator, engineer, and administrator roles.
• Standard RS485 interface with Modbus RTU protocol support; optional Ethernet (TCP/IP) and USB data export for integration into centralized MES or LIMS platforms.
• Over-temperature, over-pressure, compressor overload, and door-open safety interlocks conforming to EN 60204-1 machinery safety directives.

Sample Compatibility & Compliance

The TC-150-5 accommodates a broad spectrum of sample types—including PCB assemblies, polymer housings, lithium-ion battery modules, aerospace fasteners, and pharmaceutical packaging—without requiring modification to the chamber’s internal configuration. Its standard configuration meets baseline requirements for ASTM D3418 (thermal transitions of polymers), IEC 60068-2-1 (cold testing), IEC 60068-2-2 (dry heat), and MIL-STD-810G Method 502.6 (low temperature) and Method 501.6 (high temperature). While not intrinsically explosion-proof, the unit may be operated in conjunction with external purge systems where required by facility-specific ATEX/IECEx zoning protocols. Calibration traceability follows ISO/IEC 17025 guidelines via optional NIST-traceable temperature mapping reports (16-point sensor grid, per ICH Q5C and Annex 15).

Software & Data Management

LabCompanion’s proprietary ChamberControl™ software (Windows-based, included) enables remote monitoring, profile editing, alarm event review, and PDF report generation with digital signature fields. All temperature logs include timestamped metadata (date/time, operator ID, chamber ID, firmware version) and support audit trail functionality compliant with FDA 21 CFR Part 11 when configured with user authentication and electronic signature modules. Data files are stored in CSV and XML formats for interoperability with statistical process control (SPC) tools such as Minitab or JMP. Optional cloud-based fleet management (ChamberLink™) provides predictive maintenance alerts based on compressor cycle count, refrigerant pressure trends, and thermal load history.

Applications

• Accelerated aging studies of elastomers and adhesives per ISO 11346 and ASTM D573.
• Thermal cycling validation of solder joints and BGA packages per JEDEC JESD22-A104.
• Storage stability assessment of temperature-sensitive biologics and excipients under ICH Q1A(R2) guidelines.
• Pre-conditioning of sensors and MEMS devices prior to functional testing.
• Environmental stress screening (ESS) in manufacturing QA workflows aligned with Telcordia GR-63-CORE.
• Material coefficient of thermal expansion (CTE) correlation studies using complementary dilatometry or interferometric measurement setups.

FAQ

What is the maximum allowable sample mass for thermal stability during rapid cycling?
For optimal temperature uniformity and rate consistency, total sample mass should not exceed 15 kg. Higher loads require extended stabilization time and may reduce effective ramp rates by up to 20% depending on thermal mass and emissivity.

Is external humidity control available for this model?
The TC-150-5 is a dry-temperature-only chamber. Humidity control requires upgrading to the TH-series (e.g., TH-150-5) with integrated steam humidification and dehumidification subsystems.

Can the chamber be validated for GMP-regulated environments?
Yes—when equipped with IQ/OQ documentation packages, 3Q-certified sensors, and 21 CFR Part 11-compliant software configuration, the TC-150-5 supports qualification under EU Annex 15 and FDA guidance for equipment used in pharmaceutical process development and stability storage.

What maintenance intervals are recommended for compressor longevity?
Compressor oil and filter replacement every 24 months or 8,000 operating hours (whichever occurs first); annual calibration verification of all PT100 sensors against certified reference standards.
