A workpiece processing system has a cooling chamber enclosing a chamber volume. A workpiece support within the cooling chamber supports a workpiece having a material with an outgassing temperature, above which, the material outgases an outgas material at an outgassing rate that is toxic to personnel. A cooling apparatus selectively cools the workpiece to a predetermined temperature. A vacuum source and purge gas source selectively evacuates and selectively provides a purge gas to the chamber volume. A controller controls the cooling apparatus to cool the workpiece to the predetermined temperature, where the one or more materials are cooled below the outgassing temperature. The vacuum source and purge gas source are controlled to provide a predetermined heat transfer rate while removing the respective outgas material from the chamber volume.
