A plant is proposed to fill, at room temperature, containing elements such as bottles or other containers, preferably but not exclusively with aerated liquids and/or beer.

Said plant is equipped with special devices which allow an isobaric filling of containing elements with gaseous fluids. In general, the gaseous fluids are difficult to control, especially in natural thermic conditions and in particular at a higher temperature than 5°C because of the formation of a froth which contaminates the outer surface of the bottle.
