Configuration of Cryogenic Chamber

①Workroom	SUS304 stainless steel, which offers excellent resistance to both high and ultra-low temperatures and ensures dimensional stability during long-term deep cold testing. The standard configuration includes double adjustable sample holders. Precision sealing strips and well-engineered sealing structures effectively prevent cold air leakage, maintaining stable cryogenic conditions.
②Air circulation system	Fans circulate air throughout the workroom, ensuring uniform temperature distribution even at -120°C. Multi-point airflow design maintains temperature deviation within ±2°C, which is critical for reproducible cryogenic testing and accurate material or component evaluation.
③Heating system	The chamber uses nickel-chromium alloy heating elements, providing fast and stable heat input when transitioning from cryogenic conditions to elevated temperatures. The system can reliably reach up to +150°C, enabling rapid recovery phases and combined temperature cycling tests.
④Refrigeration system	The chamber uses a cascade mechanical refrigeration system to reach -120°C. Comprising compressors, condensers, capillaries, and evaporators, it ensures continuous, efficient deep-cold operation with reliable temperature stability.
⑤Control system	Both heating and cooling systems are precisely managed by an advanced PID control algorithm, optimized for deep cryogenic environments. Multiple safety protections—including over-temperature protection, compressor overload protection, and system fault alarms.

FAQ-Cryogenic Chamber

Q1: What is the minimum temperature the cryogenic chamber can reach?
A1: LIB industry cryogenic chambers can reliably achieve -80°C, -100°C, and -120°C, with some high-end models reaching -150°C or lower, depending on the refrigeration system. This ensures stable deep-cold performance for aerospace, automotive, electronics, and materials testing.

Q2: How fast can the chamber cool down?
A2: Cooling rates typically range from 1–3°C per minute and can be adjusted for different samples. LIB industry’s cascade refrigeration system delivers efficient, controlled cooling while maintaining precise temperature stability.

Q3: Are test data traceable?
A3: Yes. The chamber automatically records temperature, and program curves. Data can be exported for analysis or quality audits, giving engineers and managers confidence in reproducible and reliable test results.
