Thermal cycling

Most materials and components used in cryogenic application are exposed to a large number of cooling and heating cycles during their service life. To investigate behaviour and material characteristics after repeated temperature changes between deep cryogenic and up to 200 °C various test setups are in operation in our laboratory. These include lift systems with which a cryogenic shock can be induced and climatic chambers with which precisely defined temperature ramps can be approached.
Environmental and thermal aging tests are also available.
Cycling is often followed by other test campaigns for example an examination of mechanic properties on e.g. our universal testing machine.

• Temperature range (standard): -170°C … 200°C (LN2 cooling)
• Temperature range (low): 20K … 200°C (LHe cooling and LN2 cooling)
• High gradients >70K/min possible and cryogenic shocks
• Very low gradients <1K/min possible
• High cycle numbers (>10000)
• Thermal aging tests including humidity control (combined humidity and thermal cycling)
