LabCompanion HC-150 High-Low Temperature Alternating Environmental Test Chamber

Overview

The LabCompanion HC-150 High-Low Temperature Alternating Environmental Test Chamber is an engineered solution for precise, repeatable thermal stress evaluation of materials, components, and finished products under controlled climatic conditions. Based on forced-air convection and dual-stage (cascade) refrigeration architecture, the chamber maintains stable thermal profiles across its full operating range of −70°C to +150°C. Its design adheres to the fundamental principles of environmental simulation defined in IEC 60068-2-1 (cold tests), IEC 60068-2-2 (dry heat), and IEC 60068-2-14 (change of temperature), enabling standardized qualification testing for electronics, automotive parts, aerospace hardware, polymers, and packaging systems. The chamber’s thermally insulated double-wall construction, combined with PID-controlled heating and multi-stage refrigerant management, ensures minimal thermal lag and high reproducibility between test cycles.

Key Features

• Stainless steel interior chamber (SUS304) with seamless welding and rounded corners for corrosion resistance and ease of cleaning
• Cold-rolled steel exterior housing with durable epoxy powder coating for mechanical robustness and long-term stability
• Imported semi-hermetic cascade refrigeration system enabling reliable operation down to −70°C without liquid nitrogen dependency
• Digital PID temperature controller with real-time logging, programmable ramp-soak profiles, and user-defined cycle sequencing
• Integrated safety interlocks including independent over-temperature cut-off, high-pressure switch, and three-phase power monitoring
• Front-access observation window with double-layer low-emissivity glass and internal anti-fog heater
• Adjustable stainless steel shelf supports (2 standard shelves included) accommodating varied sample configurations

Sample Compatibility & Compliance

The HC-150 accommodates a broad spectrum of physical samples—ranging from printed circuit boards (PCBs) and lithium-ion battery cells to medical device housings and elastomeric seals—within its 150 L working volume (500 × 600 × 500 mm). Airflow distribution is optimized via rear-mounted centrifugal fans and calibrated baffle systems to meet IEC 60068-3-5 requirements for uniform air velocity and thermal homogeneity. All electrical and control subsystems comply with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD) and are designed for integration into ISO/IEC 17025-accredited laboratories. Optional validation packages support IQ/OQ documentation per GMP Annex 15 and FDA 21 CFR Part 11-compliant audit trails when paired with LabCompanion’s certified data acquisition software.

Software & Data Management

The HC-150 operates with LabCompanion’s TC-Link™ control suite—a Windows-based application supporting multi-chamber synchronization, remote monitoring via Ethernet or RS485, and automated report generation in PDF or CSV format. All temperature setpoints, actual readings, alarm events, and runtime logs are timestamped with millisecond precision and stored locally on encrypted SD card or network-attached storage. The software enforces role-based access control (RBAC), electronic signatures, and immutable audit trails—fully aligned with GLP and GMP data integrity requirements. Optional 21 CFR Part 11 add-on modules provide electronic signature validation, user activity logging, and change history tracking for regulated environments.

Applications

• Thermal cycling qualification of automotive ECUs per AEC-Q200 and ISO 16750-4
• Accelerated aging studies of polymer encapsulants and adhesive bonds
• Pre-conditioning of sensors and MEMS devices prior to functional testing
• Reliability screening of consumer electronics under extreme ambient exposure
• Validation of sterile barrier integrity for Class II medical packaging (ISO 11607)
• Material coefficient-of-thermal-expansion (CTE) correlation studies using dimensional metrology integration

FAQ

What is the minimum achievable temperature and how is it sustained?
The HC-150 achieves and holds −70°C using a two-stage cascade refrigeration system with R404A/R23 mixed-refrigerant circuits. Sustained sub-zero operation requires ambient room temperature ≤25°C and adequate ventilation.
Can the chamber be integrated into an existing laboratory LIMS or MES platform?
Yes—via Modbus TCP or OPC UA protocols, the TC-Link™ controller supports bi-directional data exchange with third-party lab informatics systems for automated test initiation and result ingestion.
Is calibration certification included with shipment?
A factory-as-found calibration certificate (traceable to NIST-equivalent national standards) is provided. On-site IQ/OQ services and annual recalibration are available through authorized LabCompanion service centers.
What maintenance intervals are recommended for optimal performance?
Compressor oil and refrigerant levels should be verified annually; air intake filters require cleaning every 3 months; chamber door gaskets and sensor calibration should be inspected semi-annually.
