TYY® Self-Supporting Fire fighting onion water  tank  (also known as "Onion Bladders") are ideal for use as firefighting dump tanks or emergency water supply and meet the most stringent requirements of rural/urban firefighting. An open top Fire fighting onion water  tank  (for example a 1,000 L), is the solution for inadequate or unusable supplies of water.




Detailed Images



TYY® Fire fighting onion water  tank  are manufactured by using a specially formulated Butyl Rubber / PVC membrane, while the outer protective membrane is manufactured by using a high grade tarpaulin materialTYY®  Fire fighting onion water  tank can be customized to suit a particular application or site.

The material used in the construction of TYY Onion tank is determined by the nature of the end use and the type of liquid being stored.


A “floating collar” enables them to rise to the maximum height as they are filled. The key advantageof a TYY® Onion tank over a pillow tank is the ability to fill and empty it faster than a standard pillow bladder tank. This is due to the large opening aperture within the floating collar.


The large opening also makes Onion tanks particularly easy to empty and clean. Such ability makes it easier to pack and transport, compared to a standard pillow tank.


Welding processing of firefighting onion water tank:


We use 3-layer welding production process. Namely, have two pieces of flexible membrane partially overlaped and then welded together. After that, have a third layer of flexible membrane welded along joints. In this way, tensile strength of joints is reinforced to prolong life span of water tanks.  It also can make water tanks 100% airproof.


Humanized configuration of firefighting onion water tank :


We provide customer ground sheet protector and anti-uv cover.The anti-UV cover is for covering water tank when it is using under sunshine.It can prevent the water tank from UV damaged.
