Details of Thermal Humidity Chamber

Cooling system

• Equipped with a French TECUMSEH compressor, the chamber can reach temperatures as low as -70℃ or lower, enabling reliable testing of samples under extreme cold conditions.
• Rapid cooling capability ensures shorter waiting times between test cycles, improving laboratory efficiency.
• Eco-friendly refrigerants and advanced compressor design ensure energy efficiency and long-term stability, reducing operational costs.

Air circulation system

• High-efficiency centrifugal fan combined with a noise-reduction air duct system guarantees uniform temperature and humidity distribution throughout the workroom.
• Optimized airflow design minimizes hot/cold spots, ensuring consistent test results for all samples, regardless of their placement.
• Quiet operation makes it suitable for office-adjacent labs or multi-chamber setups without disturbing the working environment.

Heating system

• Chrome-nickel alloy heater strips provide stable high temperatures up to 150℃ or higher, supporting rigorous high-temperature testing scenarios.
• Fast heating rates allow the chamber to quickly reach set points, reducing idle time during test preparation.
• Intelligent thermal management prevents overheating, ensuring sample safety and prolonged heater lifespan.

Different Types of Thermal Humidity Chamber

• Multiple models with internal volumes from 100L to 1000L (TH-100, TH-225, TH-500, TH-800, TH-1000) offer flexible options for different laboratory requirements.
• Customizable workroom capacities and shelf configurations allow optimized space utilization and simultaneous multi-sample testing.
• Designed for scalable laboratory setups, making it easy to expand or integrate with other LIB environmental testing equipment for a complete testing solution.

FAQ-Thermal Humidity Chamber

 

 

Q1: If a custom test port or viewing window is required, will there be delivery delays?

A1: Standard ports or window adjustments follow the usual production timeline, no delays. Special custom designs may add 5–10 days, but we actively manage production to get your thermal humidity chamber ready quickly.

Q2: What material and type is used for the observation window?

A2: Tempered double-layer hollow glass with anti-frost coating, ensuring clear visibility, durability, and safe operation during tests.

Q3: What is the maximum temperature change rate? Can it reach 20°C/min?

A3: Standard rate is 5–10°C/min, but we can customize up to 20°C/min or higher to meet your rapid heating or cooling needs.
