Hydac International releases new bladder integrity system

Hydac announces the introduction of a new product designed to detect
problems in the bladder of a hydraulic accumulator.

Hydac is an established name in the hydro-pneumatic accumulators segment
with over 50 years of experience in the research, development, design and
production of accumulators.

Hydac’s accumulators are pressure vessels designed and built to store
fluids under pressure. The vessels are charged with nitrogen, which is
separated from the fluid section by a piston, a bladder or a diaphragm. If not
correctly engineered, applied or maintained, hydraulic accumulators can present
a high safety risk to personnel and equipment. The new product released by
Hydac alerts personnel to any problem in the bladder.

The Bladder Integrity System (BIS) consists of a BIS bladder, a BIS
adapter and electronic components BIS 1000. When fluid penetrates the bladder,
it is detected by the bladder integrity system, which transmits a signal. The
temperature and the pressure can be monitored electronically.

Hydac offers different types of bladder integrity systems to suit
specific requirements. The BIS is available with a bladder accumulator as
initial equipment. A retrofit version is also available, both for Hydac bladder
accumulators as well as for other brands.

Key advantages of Hydac bladder integrity systems include planned repair
and maintenance interval; reduced downtime; ability to monitor pressure and
temperature during operation; and better performance enabled for the whole
hydraulic system.
