ESTECH ENERGY High Temperature Expansion Vessel- (5L-1000L)

The expansion vessel for heating systems makes available the volume for water dilation due to temperature increments, and keeps the system safe to dangerous pressure variations. The working of the expansion vessels is more important during system start-up, when water temperature rises very quickly.



The heat loss in expansion vessels with a diaphragm membrane is 60 % higher compared to balloon membrane vessels.
Bladder expansion tanks provide a better insulation , while in membrane vessels the heated water is in direct contact with the metal plate for almost half of the vessels surface
