Solar Diaphragm expansion tanks

Solar Diaphragm expansion tanks

Solar diaphragm expansion tanks are pressure devices and are used for pressure maintenance and volume compensation in closed heating, solar and cooling water systems.
A membrane divides the tank into a water section and a gas section with a pressure cushion.

Solar In-line tanks

Solar in-line tanks are pressure devices and are installed in closed heating, solar and cooling water systems in the expansion pipe in front of diaphragm expansion tanks to protect the diaphragm from inadmissible temperature loads. This is necessary for solar thermal systems, e.g. for roof heating systems with short pipe runs.

They consist of a pressure chamber which is filled with 100 % heat transfer medium during operation.
