Velcon’s DI coalescers in combination with DSO separators, contaminated fuels are cleaned to a level that meets stringent downstream fuel cleanliness standards for petroleum based diesel fuels.

The first stage in the DI coalescer removes particles through an inside-out flow and coalesces emulsified water into large droplets, which then fall to the housing sump.

In the second stage, an outside-in process, the DSO separator creates a hydrophobic barrier to block the coalesced water droplets from flowing downstream of the housing.

This multi-stage design assures the fuel is conditioned to a clean and dry state, ready for use.

  • Water coalescing is not effective in the presence of fuels containing high levels of surfactants/alcohols or unrefined biofuels
  • Detergents and additives inhibits the ability of coalescers to effectively remove water by reducing Interfacial Tension (IFT) and can eventually disarm coalescers


  • Extended equipment up-time
  • Reduced operating costs
  • Reliable fuel injector performance
  • Reduced fuel system maintenance
