Hot And Cold Thermal Shock Test Chamber

Hot and Cold Thermal Shock Test Chambers for Lab Qualification

These air‑to‑air systems expose products to rapid transitions between extreme cold and heat to reveal early failures and verify long‑term reliability. Tight control, fast transfer, and repeatable profiles help qualify electronics, automotive parts, aerospace assemblies, wire & cable, and polymer materials. Methods are aligned with IEC 60068‑2‑14, MIL‑STD, and JEDEC guidance for consistent results in modern labs.

Models and Configurations

• Two‑zone (lift‑basket): A lift basket moves samples between independent hot and cold zones. It delivers very short transfer times and minimal thermal lag. Suitable for IEC 60068‑2‑14 Na/Nb/Nc and JEDEC JESD22‑A104 profiles when speed, footprint, and energy use must be balanced.


• Tri‑zone: Adds a controlled ambient section between hot and cold. This reduces cross‑contamination and moderates extreme gradients for fragile assemblies. Choose it for stricter methods, heavy thermal loads, or very high daily cycle counts.

Key Performance and Build

• Fast transfer and recovery: Typical transfer is 5–10 s. Recovery to setpoint is about 3–5 minutes, load and profile dependent. Optional LN2 or CO2 boosts pull‑down and recovery for high mass or very short dwells.


• Temperature control: Closed‑loop PID keeps fluctuation about ±0.5°C and uniformity about ±2.0°C when properly loaded and fixtured.


• Ranges and capacity: Cold zone to −70°C (optional −80°C). Hot zone to +180°C (optional +200°C). Test volumes from ~50 to 1000 L.


• Construction: SUS304 stainless‑steel interiors, multi‑layer insulation, heated viewing window, LED lighting, silicone gaskets, and standard Ø50 mm cable ports. Anti‑sweat heaters and a durable lift mechanism support daily operation.


• Efficiency: Multi‑stage compressors, staged control, and heat recovery help reduce power draw. Refrigerants such as R404A/R448A/R23/R508B are configured as appropriate. Standby modes help during non‑test periods.

Control, Data, and Connectivity

An intuitive touchscreen PLC (7–10 inch) supports multi‑step profiling with adjustable dwell, cycles, and transfer logic. Real‑time trending, alarms, user levels, language packs, and unit switching streamline operation. Onboard logging captures temperature, timestamps, alarms, and cycle counts with export via USB/Ethernet to CSV/PDF. Optional chart recorders and LIMS/SCADA or Modbus/API integration enable audits and automation. Remote access over Ethernet/Wi‑Fi supports status, profile upload, and diagnostics.

Applications and Standards

Use these chambers to stress solder joints, BGAs, leadframes, connectors, and conformal coatings. They also evaluate polymer embrittlement, adhesion, and insulation integrity for wire & cable. Representative methods include IEC 60068‑2‑14 (Na/Nb/Nc), MIL‑STD‑883 Method 1010, MIL‑STD‑202 Method 107, JESD22‑A104, GB/T 2423.22, and GJB 150‑series.

Customization and Accessories

Mechanical options include extra cable ports, reinforced shelves and baskets, custom fixtures, larger windows, added lighting, and enhanced sealing. LN2/CO2 injection increases pull‑down and recovery for heavy loads. IO feedthroughs support power cycling, signal monitoring, and in‑situ testing. Fixtures are designed to reduce thermal lag and ensure repeatable positioning.

Quality, Safety, and Support

Manufactured in Dongguan, China, production combines in‑house CNC machining with dedicated QC, calibration, and reliability labs. Each chamber is factory‑calibrated with traceable instruments and supplied with test reports. IQ/OQ documentation is available. Protections include over‑temperature, compressor high/low pressure, fan overload, door interlock, phase loss/reversal, and LN2/CO2 safeguards. Audible/visual alarms and event logs support safe operation. Global voltages/frequencies are available, with compact footprints and casters for easy placement. Training and lifetime technical support are provided, with responsive parts and remote diagnostics.

Selection Guide and Quick Facts

• Define your largest sample size and load mass. Ensure internal space and basket capacity allow airflow clearance and future fixturing.


• Match transfer time and recovery to dwell durations and daily cycle targets. Consider LN2/CO2 for high thermal mass or very short dwells.


• Verify your method: IEC, MIL‑STD, or JEDEC. Confirm uniformity, fluctuation, and logging meet audit expectations.

Q: When should I choose tri‑zone over two‑zone?

A: Select tri‑zone for fragile parts, intermediate stabilization steps, heavy loads, or very high cycle counts. Two‑zone suits compact footprints and mainstream profiles.

Q: What are typical ranges and stability?

A: Cold to −70°C (optional −80°C), hot to +180°C (optional +200°C). Fluctuation about ±0.5°C and uniformity about ±2.0°C under proper loading.
