Tenney WSP Thermal Shock Test Chamber

 The Tenney WSP air-to-air thermal shock chamber is a fully automated dry shock test system capable of taking product 200°C to -70°C and back in 10 seconds or less. A moveable chamber automatically transfers the work load from one temperature chamber to the other. 

A dry nitrogen feed system facilitates oxygen purging in the heat chamber, preventing condensation on the metal parts of the chilled workload. A defrost heater is included to periodically defrost the cold chamber during extended tests. The lower chamber uses LN2 to reduce workload temperature.


  • Quick and fully automated transfer process for easy operation
  • Protection from condensation on metal, via dry nitrogen feed system purging oxygen, facilitates smooth functioning tests
  • Horizontal airflow provides temperature uniformity for consistent test results
  • VersaTenn V's latest software developments in environmental test chamber control make programming and diagnostics simple
  • Defrost heaters in the Tenney WSP Thermal Shock Test Chamber's cold chamber prevent ice build-up, ensuring proper machine functioning
