Large Thermal Vacuum Chamber
The Intlvac® thermal vacuum chamber is housed in the HSFL clean room facility. The Ø1.6m by 2.25m cylindrical horizontal chamber features a thermal shroud and a thermally isolated, 1m by 2.25m, thermal platen mounted on Teflon rollers. The current heater/refrigerant system is configured to handle a temperature range of -70°C to 70°C. However, the cooling circuit is rated for use with LN2 when required. LN2 feedthroughs have also been installed for localized internal heating and cooling. This thermal vacuum system is typically used for general environmental cycling and soak testing. A variety of power, signal, and thermocouple feedthroughs allow for continuous monitoring and/or operation of the object under test.
Small Thermal Vacuum Chamber
Used primarily for assembly outgassing and thermal stress testing, the Lesker® thermal vacuum chamber is installed in non-clean room lab space adjacent to the HSFL clean room facility. This Ø0.6m by 1.2m horizontal cylinder accommodates up to two heating/cooling plates capable of +/- 1°C/min for thermal shock testing. A 35L dewar may be used to feed LN2 into the cooling circuit if desired. Larger quantities may be used if necessary. The secondary chamber flanges are equipped with a variety of power, signal, and thermocouple feedthroughs to allow for continuous monitoring and/or operation of the object under test. A Stanford Research® RGA200 residual gas analyzer is also available for component/subsystem outgassing processes.
