We´re often asked how LN2 is introduced into the vacuum chamber. At Nanovac we usually go through (what we call) a LN2 manifold. The manifold serves a couple of purposes. The most important one is safety. In the LN2 manifold we allow the liquid nitrogen to "stabilize" and reach liquid phase. This parts gets very Cold (-196 degrees C). Once the manifold has reached liquid phase, we have regulation valves that allow the liquid to enter the chamber through our patented cryogenic feedthroughs. These feedthroughs are designed to reduce the risk of outside condensation, along with reducing the thermal loss.
