Temperature Cycling Test Chambers

The Belluetech Temperature Cycling Test Chamber, also referred to as the Thermal Cycling Test Chamber, is a specialized device used to assess the durability of materials under varying temperature conditions. This testing is essential for determining how well materials can endure the stress of rapidly changing temperatures, a common scenario in many real-world environments.



  • IEC 62133-2017
  • UL 1642
  • UN 38.3
  • GB31241-2014


  • Wide Temperature and Humidity Range: With a temperature range of -70℃ to +150℃ and a humidity range of 20%RH to 98%RH, the chamber can simulate a vast array of environmental conditions, suitable for diverse testing scenarios.
  • Precise Control: The chamber maintains tight control over temperature and humidity, with fluctuations limited to ±0.5℃ and ±2%RH, respectively. This precision ensures reliable and consistent test results.
  • Efficient Thermal Transition: Capable of rapidly changing temperatures (about 5℃/minute) both for heating and cooling, which is crucial for testing the resilience of materials under dynamic conditions.
  • Robust and Durable Construction: Built with high-quality materials, including 1.2mm thick SUS#304 stainless steel interiors and durable galvanized steel exteriors with electrostatic powder coating.


  • Cooling Methods: Offers both air-cooled and water-cooled systems, providing flexibility based on specific testing requirements and environmental constraints.
  • Energy Efficiency: Available in a range of power options from 8 kW to 32 kW, catering to various scales of operations.
  • Advanced Control System: Equipped with a touchscreen programmable PLC, USB and RJ485 interfaces for computer control, and specialized network control software for remote monitoring and data collection.
  • High-Quality Compressors: Utilizes top-grade compressors from Tecumseh (France) and Bock (Germany), ensuring effective and reliable cooling performance.
  • Safety Mechanisms: Features comprehensive safety protections, including explosion-proof pressure relief devices, explosion-proof chains, mobile alarm systems, networking capabilities, smoke exhaust, and fire extinguishing systems, ensuring safe operation under all conditions.
