Ultra-low Temperature Test Chamber

This chamber is built for applications where standard low-temperature testing is not enough. It provides stable cold conditions for storage, startup, reliability, and material performance validation.

• •Minimum temperature selectable: -75°C or -85°C.
• •Stable ultra-low temperature control.
• •Suitable for long-duration cold storage tests.
• •Supports low-temperature startup and performance testing.
• •Available for small, medium, or customized sample sizes.
• •Designed for laboratory and industrial reliability testing.

The chamber helps engineers evaluate how products behave under severe cold stress, including performance drift, material brittleness, sealing failure, electrical instability, and startup reliability.

Typical applications:

• •Electronic components and PCB low-temperature testing.
• •Automotive electronics, sensors, and control modules.
• •Aerospace and aviation components.
• •Plastics, rubber, metals, coatings, and composite materials.
• •Instruments, meters, connectors, and small devices.
• •Battery material and component low-temperature evaluation.
• •Battery material and component low-temperature evaluation.

It is commonly used in R&D labs, quality inspection centers, production validation, and reliability engineering departments.

The chamber uses a programmable control system for repeatable low-temperature testing and controlled test profiles. Users can set constant low-temperature conditions or temperature cycling programs according to product requirements. 

Control features:

• •Programmable touchscreen controller.
• •Constant low-temperature test mode.
• •Temperature cycling program setting.
• •Optional RS232, RS485, or Ethernet communication.
• •Optional PC monitoring and data recording.
• •Alarm protection for abnormal operation.
• •Multi-language interface available by configuration.

This supports better test repeatability, easier operation, and more efficient laboratory data management.

Ultra-low temperature testing requires stable refrigeration, reliable insulation, and uniform airflow. SANWOOD designs the chamber to support consistent low-temperature performance and long-term operation.

System highlights:

• •High-performance refrigeration system.
• •Optimized airflow for chamber uniformity.
• •Reliable operation at -75°C or -85°C configurations.
• •Modular refrigeration design for easier maintenance.
• •Modular refrigeration design for easier maintenance.
• •Safety alarms for over-temperature and system protection.
• •Configuration matched to chamber size and sample heat load.

Final refrigeration configuration should be selected according to target temperature, chamber volume, sample heat load, cooling rate, and ambient conditions.

The chamber can be configured to support test conditions related to common environmental and low-temperature testing methods, including IEC 60068-2-1 low temperature test, IEC 60068-2-14 temperature change test, ISO 16750 automotive environmental testing, and MIL-STD-810 environmental test methods.

Final compliance depends on the complete test method, sample type, calibration status, sensor setup, operating procedure, and third-party assessment.

Customization options:

• •Minimum temperature: -75°C or -85°C.
• •Chamber volume and inner dimensions.
• •Cooling rate and temperature range.
• •Viewing window and cable port.
• •Communication and data recording.
• •Sample rack or fixture.
• •Power supply by destination country.

SANWOOD Technology can provide model selection support, customization guidance, installation assistance, maintenance, repair, and technical service according to project requirements.
