TVAC Cycling (TVAC#1 Chamber)

We offer thermal vacuum cycling to ESA ECSS-Q-70-04A in both our TVAC#1 and TVAC#2 thermal vacuum test chambers. We also have an in-house FTIR facility for processing molecular contamination witness plates in accordance with ECSS-Q-ST-70-05C.

The TVAC#1 chamber features:

  • PID controlled thermal plate with resistive heating. Removable liquid channels for cooling either by chiller circulator or LN2 can be fitted on request.

  • Removable IR baffle for top-down irradiation of sample on thermal plate if required

  • Cold trap with removable fascia for lab analysis if required (our in house FTIR facility has an ATR module for qualitative analysis)

  • QCM for offgassing monitoring

  • Residual Gas Analyser (Hiden Analytical)

  • Standard 16 T-type thermocouple channels (more channels, or different TC types can be added with notice)

  • Temperature, pressure, QCM and RGA all logged digitally
