Constant Climate Cabinet

Name: Constant Climate Cabinet
Brand: Xi'an LIB Environmental Simulation Industry

The LIB industry constant climate cabinets are specifically designed for precise and long-term environmental control, making them an ideal choice for the stability storage of chemicals and materials. With a capacity range from 100 L to 1000 L, and the option for customizing larger working chamber volumes, these cabinets offer a temperature range of -70/-40/-20℃ to 150℃, with a temperature uniformity of better than ±0.5℃ and humidity adjustable from 20% to 98%RH.

The constant climate cabinet can maintain a long-term uniform and stable environment within an ultra-wide temperature and humidity range. The cabinet design ensures continuous long-term stable operation. These constant climatic cabinets are suitable for stability testing and product shelf life assessment, meeting ICH Q1A and GMP standards, ensuring consistent climatic conditions in chemical storage applications and achieving precise and repeatable results.

Standard Models: TH-100A, TH-225A, TH-500A, TH-800A, TH-1000A and more customized models.

Standard: AAMA501, ASTM D4169-16, IEC 61215, IEC 61646, IEC61108, IEC62688, MIL-STD-811D,SAE J575,ICH Q1A

Key Features and Advantages of the Constant Climate Cabinet

1. Precision Environmental Control: Maintains ultra-stable conditions with temperature deviation ≤ ±2.0 °C and uniformity ≤ 0.5 °C, combined with humidity stability ±2% RH, ensuring highly repeatable long-term storage performance.

2. Optimized Airflow Design:The optimized air duct design and vertical circulation airflow ensure uniform airflow distribution throughout the chamber. This is of vital importance for chemical or polymer products that require high-precision processing.

3. Active Dehumidification & Moisture Management: Intelligent humidity regulation keeps RH consistently low, with rapid adjustment to ambient changes, protecting hygroscopic materials from degradation.

4. Long-Term Reliability: Engineered for continuous multi-year operation, featuring smooth compressor cycling, reduced mechanical stress, and corrosion-resistant interior surfaces for sustained performance.
