UHV and HV series

Liquid is the designation Caburn-MDC gives to a series of non-electrical feedthrough products designed for the transmission of fluids and gases into high and ultrahigh vacuum environments. CaburnMDC offers two product categories: water and liquid nitrogen feedthroughs.

Water feedthroughs are used to transfer coolant to processing equipment inside a vacuum. For example, electron beam evaporation sources must be in a high-vacuum environment and generating a densely focused electron beam to produce enough heat to evaporate alumina ceramics; water cooling is therefore required to prevent damage to evaporation crucibles and electromagnetic coils used respectively to contain the molten alumina and focus the electron beam.

  • In-vacuum accessories available
  • 2 standard vacuum mounting styles
  • Custom feedthrough configurations available upon request
