Description

The biggest advantage of the Annotech HQ is its multidimensional applicability. Instead of bringing a separate valve for each pipe diameter, this bladder covers a wide range. This makes installation not only easier, but also faster. The bladder maintains its shape retention at maximum expansion and provides a reliable barrier against liquids and gases.

HQ bladders are designed for heavy-duty work. With a temperature resistance of -30 °C to 80 °C, it can withstand both frozen surfaces and hot flushing water. Its natural rubber construction provides a natural grip on the pipe wall, while its chemical resistance provides protection against the most common substances in wastewater.

Safety and Installation

Safety is paramount at Annotech. Each bladder features an integrated air pressure connection and a robust safety chain. This not only makes the bladder easy to position and inflate, but also allows it to be safely anchored under pressure, which is crucial in preventing flooding in vulnerable infrastructures.
