Indeecon thermal shock chambers deliver sub-10-second transfer times for EV battery and electronics testing per MIL-STD-810H and IEC 60068-2-14. Get a quote.
A thermal shock chamber rapidly cycles test specimens between extreme hot and cold zones, simulating temperature stress that products experience in real-world operations. Thermal shock testing is critical for detecting design weaknesses in solder joints, battery connections, seal materials, and structural integrity. Essential applications include:
Key Specifications
- Temperature range: -70°C to 200°C (model dependent)
- Basket transfer time: <10 seconds
- Capacity options: 50L to 1000L
- Two-zone / Three-zone configurations available
- PLC / controller based automation with safety interlocks
Key Features
- High-Velocity Zone Recovery: Oversized thermal reservoirs (pre-heat/pre-cool zones) enable full temperature stabilization within 5–15 minutes of transfer.
- Precision Basket Transfer: Soft-start/soft-stop pneumatic or servo-driven mechanism prevents vibration interference during transition, critical for sensitive battery testing.
- Multi-Level Safety (EV Batteries): Integrated fire suppression, H₂/CO gas sensors, pressure relief vents, and thermal runaway containment protect test staff and equipment.
- Anti-Condensation Logic: Automated dry-air purge system activates during cold-to-hot transitions, preventing false electrical shorts and condensation damage.
- Rapid Transfer Mechanism: Sub-10-second basket transfer from cold to hot zone reduces cycle time and accelerates failure detection—critical for battery development timelines.
- Oversized Thermal Zones: Pre-heat and pre-cool reservoirs absorb temperature spikes, ensuring smooth recovery to setpoint within 5–15 minutes per cycle.
- Fire Suppression & Gas Monitoring: Integrated H₂/CO sensors and automatic fire suppression protect against thermal runaway in lithium-ion battery testing.
- Anti-Condensation Purge: Automated dry-air injection during cold-to-hot transitions prevents condensation-induced false shorts—critical for accurate EV battery validation.

Frequently Asked Questions
What is the typical cycle time for thermal shock testing?
A single cycle (transfer + dwell + recovery) typically takes 20–40 minutes depending on chamber size and temperature range. Benchtop systems recover fastest at ~5 minutes per cycle.
How do you prevent condensation during cold-to-hot transitions?
Automated dry-air purge logic injects compressed, desiccant-dried air into the test zone during warm-up phases, evaporating moisture before electrical connections are energized.
Can these chambers test lithium-ion battery packs safely?
Yes. Our large-scale systems include fire suppression, H₂/CO gas sensors, thermal runaway containment vents, and emergency shutoff—certified for safe EV battery testing.
What data logging is available?
NABL-compliant high-speed data logging at 1-second intervals captures temperature, humidity, pressure, and gas sensor readings with time-stamped validation for regulatory compliance.
