Central Helium Liquefier - Cold Boxes

Cold Boxes

Two large Cold Boxes dominate this room inside the Central Helium Liquefier. Heat exchangers, cold compressors and other equipment needed to chill Helium down to a temperature of -456F are insulated from room temperature within these containers. This equipment requires a huge amount of electricity to operate. It costs about a million dollars a year to pay the power bill.
