Abstract
The invention relates to a method for drying a chamber comprising a predominantly protective-gas atmosphere in the chamber under positive pressure, which has an operating pressure p1 and a predetermined minimum pressure pmin, wherein the minimum pressure pmin of the gas chamber is monitored and the operating pressure p1 is greater than the minimum pressure pmin, wherein the method comprises the following steps: a) removing of a partial quantity Vi of the protective gas from the chamber, wherein the partial quantity Vi is equivalent to the pressure differential Δp, which is smaller or equal to the differential between p1 and pmin, b) introducing a partial quantity V2 of a dry or dried protective gas into the gas chamber up to a gas pressure p2, which is greater than pmin and c) repeating method steps a) and b) after a predetermined waiting time Δt. The invention further relates to an arrangement for carrying out the method.
