  • Low humidity generator
    Patent number: 11117105
    Abstract: The embodied invention is a low humidity generator which encapsulates essential piping, pressure regulator, flow regulator, and saturator in a sealed vacuum chamber. Additionally, a Stirling piston type cooler is used to cool the saturator. This eliminates atmospheric water vapor permeation and the need for thermal insulation surrounding the piping and control units. Also, the humidity generator has improved cool down characteristics, improved thermal control, and better maintenance access.
    Type: Grant
