Horizontal and Vertical Bladder Tanks – Pre-Piped

FIRETECH Bladder Type Foam Proportioning Unit (Bladder Tank) is provided for accurate foam proportioning of the foam concentrate with the fire-water over a wide range of flow.

FIRETECH Horizontal and Vertical Bladder Tanks consist of the following main components i.e. Foam Vessel, Foam Bladder, Water Piping, Foam Piping, Vent & Drain Valves and Level Indicator.  

During operation the water is charged into the bladder tank between the vessel wall and the bladder to the inlet water pressure. Bladders transfers this water pressure to the foam concentrate stored inside the bladder, this causes pressurization of the foam concentrate.

Pressurized foam concentrate is delivered to the foam concentrate inlet of the foam proportioner. A foam concentrate orifice is provided for accurate mixing of the foam concentrate into the fire-water.

The metering pressure drop is created in the foam proportioner which causes the foam concentrate to flow into the fire water stream.

Bladder tanks with horizontal layout are referred as horizontal bladder tanks. Firetech manufactures UL Certified Horizontal Bladder tank from range of 200L to 15000L capacity.

Bladder tanks are also available in vertical layout. They functions same as Horizontal Bladder Tank only difference. In vertical bladder tanks, water enters the tank from left side and forced out foam from right side or vice versa. Vertical bladder tanks are preferred in case of space constraint.

Firetech manufactures UL Certified Vertical Bladder Tank from range of 200L to 15000L capacity.
