Flexible solutions:
Titan Industrial is highly specialized in the manufacture of tailor-made replaceable tank bladders for expansion tanks, pressure vessels, and water hammer arrestors.
We have a flexible approach to our customers requirements and produce the bladders in all shapes and sizes. With vast experience in special dimensions, upto 100.000 litres and more.
We use polyurethane (ether) film in thickness of 1 mm, which allows easy handling in installation and low transport costs due to its light weight (around 30% of a others bladders), with highest quality and durability.
Alternatively we are also manufacturing butyl bladders, so our clients can decide between the two technical materials as per their customers requirements.
The bladders are suitable for potable water systems, waste water, irrigation and other installations.
The bladders comply with the consumer goods laws of the European Union and the U.S.A. and are approved for contact with potable water and foodstuffs.
