Coalescers (P45)

Coalescers are also referred to as filter water separators. The separation of liquid-liquid dispersions can be accomplished with the help of coalescer elements. These dispersions are more or sometimes less unstable and can sometimes be separated under certain preconditions due to the difference in density between the phases. In addition to the density difference, viscosity and interfacial surface tension also play an important role in the separability. The process by which droplets flow together is referred to as coalescence.

This product line finds use in separation technology, whether in the separation of a liquid mist from a gas flow, of two emulsified liquids or in the stripping of gases from a liquid.

Application areas

  • Phase separation of liquids with different densities.
  • Dehydration of oils, diesel & aviation fuels
  • Elimination of oil/diesel traces (components) in water circuits or gas flows

Throughput capacity

This is dependent on the filter size. Throughput capacities from 15 m³/h to 750 m³/h are possible.
