Two types of tanks are used for foam storage: atmospheric and bladder. 

An atmospheric tank is used for storing water or foam concentrate in combination with a pump and a proportioner. The size of the tank and the built-in pipe and hose connections can be adapted to meet your requirements. 

A bladder tank is used for storing foam concentrate in combination with a proportioner. The advantage of a bladder tank is that an external pump for adding foam concentrate is not required - the water pressure of the extinguishing system is used instead. Bladder tanks can be installed vertically or horizontally.
