OPEN EXPANSION VESSELS
304 STAINLESS STEEL / GALVANIZED / POLYETHILENE
Opened Expansion tanks are used as safety accessories
in the heating systems where, due to legal reason it is
vorbidden to install closed expansion tanks systems.
In Italy, for the water fireplaces, they are still one of
the most simple and economic solution. Expansion
tank is composed by a cover unit where all the security
piping of outlet pipe for too full , supplying and systems
charge , should arrive. Its rule is to merge the water in
excess due caused by temperature increase. Expansion
Tank should be placed on the higher point reached by
the water and should have an expanding volume not
less the expansion volume developed by all the water
contained into the system , whose value should be
declared in the project.
Expansion volume need it in the system is calculated by
the following formula:
“Ve = C x e”
Where C is the water contained into the system and “e”
is equal to the difference between the expansion factor
of the water at the minimum conceivable temperature
with sleeping system and the expansion factor of the
water at boiling temperature of atmospheric pressure.
Considering the first water temperature equal to 10°C
and the boiling one at 100°C
“e” = 0.0431
If need you can connect more than one tanks all
together.
