The hot gas bypass feature allows the warm nitrogen gas in the supply line to be
vented when a fill is initiated. This stops warm gas from entering the freezer
storage space and helps maintain a stable temperature gradient while increasing
the efficiency by reducing unnecessary liquid nitrogen evaporation during fills.
This feature will increase the efficiency of any supply system whether using
liquid cylinders or a large bulk tank and vacuum insulated piping.
