Vertical closed expansion tank

In central heating systems, when there is no suitable place to install an open expansion source, or due to the climatic conditions of the region (cold regions), it is not possible to use open expansion sources, or it is necessary that the water temperature of the boiler is more than 100 degrees (scalding boiler), the expansion tank is used to neutralize the pressure caused by the increase in water volume or to create pressure on the system in order to raise the boiling temperature of water.

Compared to open tanks, closed expansion tanks have a lot of additional equipment and are rarely used in the industry due to the relatively complex control system and the need for technical knowledge of operators.

In these tanks, a part of the tank is filled with water and then nitrogen gas (N2) is used in the empty part of the tank to create pressure. Considering the operation system of this device, the mentioned tank must be equipped with a pressure control switch, safety valve, pressure gauge, level control, level display, and solenoid valves for the nitrogen charge path and water discharge path.

According to the installation space, these tanks are made in horizontal and vertical types.

It is suggested to consult with the experts of Pak Fan Bohar Industries regarding choosing the right size and model for vertical closed expansion tanks.
