Stoppers for the chemical cleaning of plate heat exchangers - ONC
Working in collaboration with EDF, Pronal has developed a stopper system capable of plugging the inlets and outlets of plate heat exchangers. These are stoppers for the chemical cleaning of plate heat exchangers. They are designed for nuclear sites.
Furthermore, the ONC stoppers can be remotely installed in the pipes using a rod and a cradle to prevent the stopper from being damaged by any abrasive surfaces on the plates.
The stoppers for the chemical cleaning of plate heat exchangers are highly resistant to cleaning fluids. Finally, the inflatable stoppers remain completely air/watertight up to a pressure of 3.4 bar. Morever, different dimensions are available: ONC 240, ONC 280 and ONC 380.
