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

Overview

The LabCompanion LC-150 High-Low Temperature Alternating Environmental Test Chamber is an engineered solution for accelerated reliability testing under dynamically controlled thermal stress conditions. Designed in accordance with international environmental simulation standards—including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and ISO 16750-4 (automotive environmental stress)—this chamber implements a Balanced Temperature and Humidity Control (BTHC) system to ensure precise, repeatable, and traceable thermal cycling profiles. Unlike static temperature chambers, the LC-150 supports fully programmable alternating cycles between extreme low and high temperatures—enabling rigorous evaluation of material dimensional stability, solder joint integrity, polymer crystallinity shifts, electronic component thermal expansion mismatch, and sealant adhesion fatigue. Its dual-stage refrigeration architecture—comprising hermetically sealed European-origin compressors and a cascade refrigerant blend (R507/R23)—delivers stable operation across the full −70 °C to +150 °C range, even under continuous load and ambient conditions up to +30 °C.

Key Features

• Robust chamber construction: Exterior housing of electrostatically painted cold-rolled steel or brushed SUS304 stainless steel; interior chamber lined with mirror-finish, cryo- and thermo-resistant SUS304 stainless steel.
• High-efficiency thermal insulation: 120 mm thick composite layer combining high-density polyurethane foam and fiberglass—minimizing thermal bridging and energy consumption while maintaining uniform internal temperature distribution (≤ ±2.0 °C).
• Intelligent control architecture: 7-inch color touchscreen LCD controller supporting both fixed-value and multi-segment programmable operation (10–140 programs, up to 1400 total segments); PID algorithm with ±0.1 °C temperature resolution and ±1% RH humidity resolution (when equipped with optional humidity module).
• Dynamic thermal performance: Verified heating rate of ≤30 minutes (0 °C → +150 °C) and cooling rate of ≤85 minutes (+20 °C → −70 °C), validated per ASTM E145 Annex A3 methodology under no-load, 20 °C ambient conditions.
• Integrated safety redundancy: Independent mechanical over-temperature limiter, compressor high-pressure cut-off switch, motor overcurrent protection, ground-fault circuit interrupter (GFCI), and automatic power recovery with configurable restart logic after mains interruption.
• Modular service design: Four locking casters for mobility; Φ50 mm cable port with removable cover; two adjustable stainless-steel shelves; standardized RS-232/RS-485 communication interface (optional); GLP-compliant audit trail logging available via optional software package.

Sample Compatibility & Compliance

The LC-150 accommodates a broad spectrum of test specimens—from printed circuit boards (PCBs) and automotive ECUs to aerospace composites and medical device housings—within its 150 L working volume (500 × 500 × 600 mm internal dimensions). Its uniform airflow design, driven by forward-curved centrifugal blowers and optimized duct geometry, ensures minimal thermal gradient deviation across the test space—critical for conformance to MIL-STD-810H Method 502.7 (temperature shock) and JEDEC JESD22-A104F (temperature cycling). The chamber meets CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and its electrical architecture complies with IEC 61000-6-2/6-3 immunity and emission standards. For regulated industries, optional validation packages support IQ/OQ documentation aligned with FDA 21 CFR Part 11 data integrity principles and ISO/IEC 17025 calibration traceability.

Software & Data Management

While the embedded controller provides real-time monitoring and local data logging (including trend curves for temperature, alarm status, and cycle phase), the LC-150 supports optional PC-based software for advanced test orchestration and compliance reporting. This software enables remote parameter upload/download, automated report generation (PDF/CSV), user-level access control (admin/operator/guest), and electronic signature capture—fully satisfying ALCOA+ data governance criteria (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Data export formats include IEEE 1584-compliant time-series logs, enabling integration into enterprise LIMS or MES platforms. All firmware updates are digitally signed and version-locked to prevent unauthorized modification.

Applications

• Electronics reliability: Thermal cycling qualification of semiconductors, connectors, and flex-rigid PCBs per IPC-9701A and AEC-Q200.
• Automotive component validation: Testing of sensors, actuators, and infotainment modules under ISO 16750-4-defined climatic profiles.
• Materials science research: Characterization of thermoplastic elastomer hysteresis, shape-memory alloy transition kinetics, and battery cell thermal runaway propagation thresholds.
• Pharmaceutical packaging: Accelerated aging studies of blister foil lamination integrity under cyclic thermal stress (ICH Q1A).
• Aerospace hardware screening: Pre-qualification of avionics enclosures and optical sensor mounts per RTCA DO-160 Section 4.11.

FAQ

What is the standard warranty period for the LC-150 chamber?
LabCompanion provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship, excluding consumables and damage from improper use or environmental conditions outside specified operating limits.
Can the LC-150 be configured for humidity control?
Yes—the base LC-150 is temperature-only; however, a humidity-enabled variant (LC-150H) is available with steam humidification, refrigerant dehumidification, and dry-wet bulb RH sensing, compliant with IEC 60068-2-78.
Is third-party calibration certification included with delivery?
Factory calibration certificates (traceable to NIM or CNAS-accredited labs) are provided as standard; full IQ/OQ documentation and on-site SAT verification are available as optional services.
Does the chamber support Ethernet or USB connectivity?
Standard communication is RS-232/RS-485; Ethernet (TCP/IP) and USB host interfaces are available as factory-installed options—enabling direct integration with SCADA systems and automated test frameworks.
How is thermal uniformity verified during installation qualification?
Uniformity mapping is performed using nine calibrated PT100 sensors positioned per IEC 60068-3-5 Annex B, with results documented in the final SAT report—including worst-case deviation, average deviation, and spatial gradient analysis.
