Surge Vessels

Bladder Vessels

SURGEx-BV Series

SURGEx-BV series is a shock absorber that deal with the  overpressures created by the water hammer. The vessel is fitted with a bladder inside which the water is contained and consequently, water is not in direct contact with the vessel shell. Generally, the bladder material is Polyurethane, which has high mechanical and physical characteristics. Other types of materials can also be provided if needed. The vessel can either be horizontal or vertical and the volume of a single vessel can be up to 80,000 liters. Should a bigger volume is requested as per the surge analysis, more vessels can be installed in parallel in this case.

Compressor Vessels

SURGEx-CV Series

SURGEx-CV series is a shock absorber that deal with the overpressures created by the water hammer. The vessel is connected to a compressor that compensate the air that can be dissolved into the water or that flow into the system when surge occurs. The volume of a single vessel can be up to 80,000 liters. However, the vessels can be installed in parallel when greater volumes are required depending on the surge analsyis.

Self-Aerating Vessels

SURGEx-SA Series

SURGEx-SA series is a self aerating vessel that act as large vacuum breaker and it is used when the surge pressures are negative (vaccum). The vessels are designed to allow the injection of a certain amount of air and break the vaccum inside the pipeline accordingly.
