The Ymer bladdertank is a Carbon or Stainless Steel pressure vessel containing an elastomeric separation bladder between water and foam concentrate. The bladder permits water pressure to be transfered to the foam concentrate and mixed into the water stream with the use of a foam proportioner. This technology is widely spread in firefighting thanks to its reliability and flexibility to changing pressures and flowrates.
Ymer bladdertanks are constructed according to the European pressure vessel directive and can also be supplied as ASME code version. We supply vertical and horizontal bladdertanks ranging from a size of 200 liters up to 20000 liters.
