Expansion Systems

Safety along the entire line

Liquid chlorine expands strongly when heated and can create extremely high pressure as a result. Consequently, all line systems for liquid chlorine must be equipped with a expansion system. Expansion systems consist of a rupture disk, a contact pressure gauge as well as an optional relief valve. The integrated contact pressure gauge indicates and provides for remote signalling of the failure.
