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 w

hile 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.
