Abstract

A method and an apparatus for regulating an atmosphere in an essentially closed space are described. The atmosphere contains a condensable substance, inert gas and oxygen, and the method comprises the following steps: withdrawing said atmosphere from the space and passing the same, forming a process gas flow to a concentrator unit wherein said condensable substance is separated from the rest of said process gas flow; returning at least a part of said process gas flow to the space; and bringing said condensable substance from said concentrator unit to a condensation unit and condensing said condensable substance in said condensation unit.
