When you're testing materials, devices, or sensors in different environments, it's important to use a chamber that's stable, gives repeatable results, and meets strict standards.
LIB's Cryogenic Chamber delivers reliable ultra-low temperature control from mechanical-compressor cooling - removing the need for liquid nitrogen - and supports demanding applications from aerospace component qualification to superconducting material screening, with clear, traceable data and rugged safety features.
【How does the Cryogenic Chamber reach −120 °C ?】
LIB's Cryogenic Chamber uses an advanced cascade mechanical refrigeration system driven by high-efficiency compressors. The cascade architecture (multi-stage refrigerant loop) provides controlled, continuous cooling down to −120 °C while maintaining precise temperature stability. Key enablers:
French Taikang Mechanical Compressor: Replaces liquid nitrogen, eliminating handling, refilling, and related safety concerns while providing stable and continuous ultra-low temperature cooling.
Precise Cascade PID Controllor: Incorporates PT100 Class A sensors for tight temperature regulation and rapid response to load changes, ensuring consistent test conditions.
Energy Efficiency: The system is designed for optimal energy consumption, reducing operational costs while maintaining performance.

【What can LIB's Cryogenic Chamber do? 】
Ultra-low temperature qualification (down to −120 °C)
Test polymers, composites, and structural metals at −120 °C to check how tough they are, how they break, and when they become brittle, all with consistent, repeatable results.
Workroom
Wide dynamic range & thermal cycling
Single system covers −120 °C to +150 °C, enabling extreme thermal-delta cycles in one chamber without swapping equipment.
Mechanical-compressor cooling - no liquid nitrogen
Cascade compressor refrigeration provides continuous cooling to −120 °C, eliminating liquid-nitrogen handling, refill logistics and cryogen safety overhead.

Traceable precision & control
PT100 Class A sensors and cascade PID control deliver typical stability of ±0.5 °C and uniformity about ±1.5 °C across the workroom. Data logging via Ethernet/USB produces audit-ready CSV/PDF records.
Sensors
Predictable performance
Typical cool-down to −120 °C: 90–180 minutes (load dependent). Typical cool rates: 1.0°C/min (ambient → −40 °C faster). Programmable capacity of PID controller: up to 120 profiles with 100 steps each.
Built-in safety & usability
Over-temperature protection, auto-defrost cycles, high-pressure interlocks, fail-safe power cut-offs, remote alarms and multi-language touchscreen UI for straightforward operation.
