LabCompanion HC-80 High-Low Temperature Alternating Environmental Test Chamber

Overview

The LabCompanion HC-80 High-Low Temperature Alternating Environmental Test Chamber is an engineered solution for accelerated environmental stress testing under precisely controlled thermal conditions. Based on the principle of mechanical compression refrigeration—employing either single-stage or cascade (two-stage) vapor-compression cycles—the chamber delivers stable, repeatable temperature profiles across a wide operational range (0 °C to +150 °C). Designed in strict compliance with international test standards including GB/T 10589, GB/T 10592, GB/T 2423.1, GB/T 2423.4, and MIL-STD-810D Method 502.2 and 507.2, the HC-80 supports qualification testing for electronic components, PCB assemblies, lithium-ion batteries, optical modules (e.g., fiber optics, LCD panels), and automotive-grade sensors. Its thermally optimized chamber architecture enables rapid thermal transitions—achieving ≤20 min from ambient (20 °C) to 0 °C and ≤20 min from 0 °C to +150 °C—while maintaining temperature uniformity ≤±2.0 °C and stability ≤±0.5 °C under no-load conditions.

Key Features

• Energy-efficient design: Reduces power consumption by up to 30% and water usage by 20% versus conventional chambers; utilizes R507—a zero-ozone-depletion-potential (ODP), low-global-warming-potential (GWP) HFC refrigerant compliant with EU F-Gas Regulation (EU No 517/2014).
• Dual-mode refrigeration system: Configurable single-stage or cascade mechanical compression with air-cooled condensers; features imported hermetic rotary compressors (Europe/USA origin) for extended service life and low acoustic noise.
• Corrosion-resistant construction: Inner chamber fabricated from brushed SUS304 stainless steel; outer enclosure options include SUS304 or electrostatically powder-coated cold-rolled steel; high-density polyurethane foam + fiberglass insulation ensures thermal integrity.
• Advanced control architecture: VT9620 Taiwan-sourced fixed-setpoint PID controller with LED display (0.1 °C resolution); supports forward/reverse control action selection, auto-tuning, and real-time thermal response visualization.
• BTHC (Balanced Temperature & Humidity Control) thermal regulation: Independent heating (Ni-Cr alloy heaters) and cooling circuits enable precise, non-overlapping temperature ramping and soaking.
• Uniform airflow distribution: Centrifugal blower-driven forced convection system with adjustable multi-directional air outlets eliminates thermal stratification and dead zones—validated per IEC 60068-3-5 for temperature homogeneity.
• Integrated safety redundancy: Dual independent overtemperature cutoffs, compressor overcurrent/overload protection, high-pressure refrigerant switch, phase-loss detection, earth-leakage circuit breaker, and low-water-level interlock.

Sample Compatibility & Compliance

The HC-80 accommodates samples up to 400 mm (W) × 500 mm (H) × 400 mm (D) within its 80 L working volume. Standard 50 mm diameter cable ports (with removable caps), two adjustable stainless-steel shelves, and front-access water reservoir support flexible DUT integration—including powered devices, battery packs, and optoelectronic subassemblies. The chamber meets structural and performance requirements for ISO/IEC 17025-accredited laboratories conducting environmental qualification per IPC-J-STD-020, JEDEC JESD22-A104, and AEC-Q200. All electrical components conform to IEC 61000-4 EMC immunity standards; control firmware supports audit-ready event logging for GLP/GMP-aligned workflows.

Software & Data Management

While the base HC-80 operates in fixed-setpoint mode via the VT9620 controller, optional RS-485/RS-232 communication interfaces enable integration with third-party SCADA platforms (e.g., LabVIEW, MATLAB, or custom MES systems) for remote monitoring, data acquisition, and automated report generation. Optional programmable controllers (e.g., Eurotherm 3500-series) provide multi-segment ramp-soak profiles, alarm history export (CSV), and time-stamped digital logs compliant with FDA 21 CFR Part 11 when paired with validated user access controls and electronic signature protocols.

Applications

• Temperature cycling validation of printed circuit boards (PCBs) and solder joint reliability per IPC-TM-650 2.6.7.
• Thermal endurance screening of lithium-ion pouch and cylindrical cells under IEC 62133 and UN 38.3 preconditioning protocols.
• Pre-conditioning of optical components (LCDs, OLEDs, fiber connectors) prior to humidity exposure or mechanical shock testing.
• Accelerated aging studies for automotive ECUs and ADAS sensors under ISO 16750-4 temperature profiles.
• Stability testing of pharmaceutical packaging materials per USP and ICH Q1A(R2) guidelines.

FAQ

What is the standard temperature range and accuracy specification for the HC-80?
The HC-80 operates from 0 °C to +150 °C. Under no-load, 20 °C ambient conditions, it achieves temperature uniformity ≤±2.0 °C across the working volume and stability ≤±0.5 °C during soak periods.
Can the HC-80 be configured for humidity control?
No—the HC-80 is a dry-thermal-only chamber. For combined temperature/humidity testing, LabCompanion recommends the HD series (e.g., HD-80) with integrated steam humidification and dehumidification modules.
Is the refrigerant R507 compliant with current environmental regulations?
Yes—R507 is a zeotropic blend (R125/R143a) with zero ODP and GWP = 3985, approved under EU F-Gas Regulation Annex I for industrial refrigeration applications through 2030; full technical safety data sheets (SDS) are provided with shipment.
What electrical supply configurations are supported?
Dual-input compatibility: AC 220 V ±10%, 50 Hz (single-phase + PE) or AC 380 V ±10%, 50 Hz (three-phase four-wire + PE). Input terminals are rated for continuous operation at 500 V isolation per IEC 61000-4-5 surge immunity.
Does the HC-80 include validation documentation for IQ/OQ protocols?
Yes—each unit ships with a Factory Acceptance Test (FAT) report, calibration certificate traceable to NIM (China National Institute of Metrology), and a comprehensive user manual containing SOP templates for Installation Qualification (IQ) and Operational Qualification (OQ) per ASTM E2500.
