When products are exposed to sudden and extreme temperature changes—like moving from scorching desert heat to freezing alpine conditions—the risk of cracks, warping, and functional failure rises sharply. For manufacturers in electric vehicles, aerospace, electronics, and automotive components, such failures can cause recalls, certification delays, or safety hazards.
LIB industry provides the solution with its thermal shock chamber –70 ℃ to +220 ℃, engineered to deliver fast, precise, and repeatable hot and cold shock testing.

Sudden temperature changes can compromise product safety, especially for lithium-ion batteries, delicate electronic components, and automotive modules. Conventional testing methods often lack speed, accuracy, or global compliance. LIB industry’s hot and cold shock chamber solutions are designed to replicate extreme real-world conditions safely and efficiently, giving you reliable, certifiable data every time.
LIB industry’s 2-zone air-to-air thermal shock chamber uses a basket elevator to transfer samples between a hot zone and a cold zone. Unlike liquid nitrogen cooling, the chamber uses conditioned air streams to achieve rapid and controlled temperature changes.
Core Parameters:
Temperature Range: –70 ℃ (cold zone) to +220 ℃ (hot zone)
Transition Time: <3 seconds (basket movement between zones)
Recovery Time: ≤5 minutes to stabilize after transfer
Load Capacity: Up to 80 kg with adjustable SUS304 stainless-steel shelves
Air Circulation: Dual centrifugal fans, ≤65 dBA low-noise operation
Controller: PID closed-loop with PT100 Class A sensors (±1 ℃ accuracy)
These parameters ensure accurate, repeatable results for even the most sensitive components.

LIB industry’s hot and cold shock chamber is fully certified to meet international standards, guaranteeing that your reports are recognized worldwide:
IEC 60068-2-14: Environmental testing – change of temperature (Test Na)
ISO 16750: Road vehicle environmental tests for electrical/electronic equipment
VW 80000: Volkswagen automotive component standards
UL 2580: Safety for lithium-ion batteries for electric vehicles
Compliance with these standards provides confidence that your testing data is globally accepted by OEMs and regulatory agencies.
For lithium-ion batteries, safety during thermal shock testing is critical. LIB industry offers explosion-proof thermal shock chambers with reinforced steel housing, pressure relief vents, sensitive smoke detectors, and automatic shutdown systems.
Battery Testing Workflow:
1. Sample Mounting: Adjustable/removable shelves support large battery modules.
2. Cable Hole Access: 100 mm stainless-steel ports allow power-on testing and real-time voltage/temperature monitoring without breaking chamber integrity.
 |  |
3. Thermal Cycling: Basket moves samples between –70 ℃ and +220 ℃ in under 3 seconds.
 |  |
4. Data Logging: PID and PT100 sensors capture ±0.5 ℃ uniformity.
 |
Supported Battery Standards: UN 38.3, IEC 62660, UL 9540A.
LIB industry also offers three-zone thermal shock chambers , where samples remain stationary while airflows cycle between hot, cold, and ambient zones. This minimizes mechanical stress and is ideal for fragile or high-frequency testing applications.
