Open Expansion Vessels are used as
safety accessories in heating systems where, for
regulatory issues, systems cannot be installed
Closed expansion vessel. In Italy, for generators
powered by non-pulverized solid fuels
such as water thermo-fireplaces, vessel systems
of open expansion still represent the
simplest and most economical solution. The vase of
expansion consists of a covered container
to which the connections of the
safety pipe of the vent pipe, too much
full, power and system loading.
Its function is to absorb the increase in
volume of water resulting from the increase in
temperature.
Technical Features
General Features
Cordivari Stainless Steel Expansion Vessel
The expansion vessel consists of a covered container that connects the safety pipes, vent pipe, overflow pipe, supply pipe, and system fill pipe. Ideal for open-circuit heating systems (thermal fireplaces, biomass boilers), its function is to absorb the increase in water volume resulting from the increase in temperature. The expansion vessel must be located above the highest point reached by the water circulating in the system and must have an expansion volume no less than the expansion volume of all the water contained in the system, which value must be specified in the design. If necessary, multiple interconnected vessels can be used instead of a single vessel.
