Large-Chamber Customization: Modular chamber design accommodates complete battery packs and energy storage systems, with reserved high-voltage interfaces for integrated charge/discharge testing.
Uniform Temperature Distribution: CFD-optimized airflow design ensures uniform temperature and humidity throughout the large chamber, minimizing localized temperature variations under full-load conditions.
Wide Operating Range: Broad temperature and humidity ranges with programmable cycling support national-standard high/low-temperature and damp-heat cycle testing.
Battery Safety Protection: Integrated pressure relief, smoke detection, and over-temperature interlocks help mitigate risks associated with battery thermal runaway.
Continuous Operation: Integrated temperature and humidity control with intelligent defrosting supports long-duration testing around the clock, 24/7.
Intelligent Monitoring and Control: Programmable test profiles, multi-point data acquisition and logging, and remote monitoring enable full test data traceability.

| Chamber Construction | |
| Exterior Material | Cold-rolled steel sheets with a powder-coated finish |
| Interior Material | High-quality SUS 304 stainless steel |
| Refrigeration Compressor | Hermetic compressor manufactured by BITZER, Germany |
| Controller | TEMAK in-house developed controller |
| Monitoring System | |
| Explosion-Proof Infrared Cameras | Up to two explosion-proof infrared cameras can be installed inside the chamber, one at the front and one at the rear |
| Safety Protection Systems | |
| Pressure Relief Device | An explosion-proof pressure relief device can be installed on the top of the chamber |
| Water-Filling System | An optional water-filling system is available. In the event of an abnormal condition, the system triggers a power cut-off and alarm. Water can then be introduced into the chamber by opening the valve |
| Fire Suppression System | Supports both automatic and manual fire suppression modes |
| Smoke Detector | When the smoke concentration inside the chamber exceeds the alarm threshold, an audible and visual alarm is triggered, the chamber operation is stopped, and an alarm signal is output |
| Gas Monitoring System | Equipped with hydrogen and carbon monoxide sensors. If either gas concentration exceeds its preset threshold, the system immediately cuts off power, triggers an alarm, and activates the ventilation system |
| Fuel Leak Monitoring System | Designed to detect and alarm gasoline leaks from vehicles inside the walk-in chamber. When the fuel concentration exceeds the preset threshold, the system immediately cuts off power, triggers an alarm, and activates the ventilation system |
| Smoke Exhaust System | Automatic mode: The exhaust system installed at the top of the chamber activates automatically when gas concentration exceeds the preset limit. |
| Voltage and Temperature Data Acquisition System | Each chamber is equipped with a voltage and temperature data acquisition system with at least 240 channels. Each system can operate independently and supports CAN communication |
