Advantages of the Fast Change Rate Thermal Cycle Chamber
1. Rapid Thermal Cycling for ESS Applications: This chamber is specially designed for high-speed temperature transition testing, offering adjustable ramp rates of 5 / 10 / 15 °C per minute, with optional customization up to 20 °C per minute. It supports ESS testing by accelerating the detection of potential material or component failures in a shorter time compared to traditional systems.
2. Broad Temperature Capability for Harsh Environments: The system operates within a wide temperature range from –40 °C to +170 °C, with optional extensions down to –70 °C or –86 °C. This allows accurate simulation of extreme thermal conditions, making it suitable for batteries, automotive electronics, and aerospace components under demanding environments.
3. High Stability and Uniform Temperature Distribution: With advanced airflow design and precise PID control, the chamber maintains temperature fluctuation within ±0.5 °C and uniformity within ±2 °C, even during rapid transitions. This ensures all samples are exposed to consistent conditions, improving test reliability and repeatability.
4. Efficient Operation and Flexible Programming: A smart touchscreen controller enables multi-step programming and long-duration automated testing. High ramp rates significantly reduce overall test time, improving throughput and making laboratory testing more efficient.
5. Durable Structure and Comprehensive Safety Protection: Built with a SUS304 stainless steel interior and reinforced external structure, the chamber is designed for long-term industrial use. It also includes multiple safety protections such as over-temperature shutdown, electrical safety systems, and optional explosion-proof design, ensuring safe testing of high-energy devices like lithium batteries.

FAQs
Q1: What temperature range supports the 10 °C/min fast change rate in the chamber?
A: In LIB TR series fast thermal cycle chambers, the 10 °C/min ramp rate is typically measured under no-load conditions and is applicable within the temperature range of –60 °C to +85 °C. This setting ensures stable and efficient thermal transition performance during testing.
Q2: How can I estimate the time required to reach a specific temperature?
A: The chamber's ramp rate (°C/min) indicates how quickly the temperature changes. By calculating the difference between the starting temperature and the target temperature, users can easily estimate the approximate time needed to reach the desired setpoint based on the selected heating or cooling rate.
Q3: Can the ramp rate be adjusted during a test program?
A: Yes, the ramp rate can be programmed and modified through the controller before or during test setup. Users can select different profiles (such as 5, 10, or 15 °C/min) depending on the test standard or application requirements.
