Do liquid nitrogen cooled chambers cost more than conventional ones?
Generally a liquid nitrogen (LN2) cooled chamber will cost considerably less than a mechanical cooled one of equivalent size. Maintenance costs are also lower and their footprint is smaller too so they take up less space and they are relatively quiet in operation. However LN2 is more expensive than electricity, it requires specialist installation and as a refrigerated liquefied gas you will need to be aware of some potential hazards.
