Tenney WSP Air-to-Air Thermal Shock Chamber -75°C to 200°C

Description

Tenney WSP Series Thermal Shock Chambers The Tenney WSP air-to-air thermal shock chamber is a fully automated dry shock test system capable of taking product from 200 C to -70 C and back in 10 seconds or less. A movable chamber automatically transfers the workload 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.
