Solar container tank diaphragm type

A pressurised membrane (also called a bladder or diaphragm) allows the ingress or egress of water from the system to maintain a constant pressure. As water cannot be compressed in a closed water circuit, any increase in temperature needs to be accommodated and this is done by the. This revolutionary technology has the potential to reshape the solar industry by vastly imp oving solar panel efficiency and du ers for use. The closed expansion vessel with membrane consists of a closed container divided into two parts by a membrane which separates water from gas (nitrogen or air) and which acts as an expansion compensation device. Container with diaphragm and nitrogen cushion for static pressure control with threaded connection, wall installation.
