Droplet Separator Systems

Lechler droplet separators improve processing operations

Droplet separators have long played a vital role in many process operations and in gas washing plants. The topic Droplet Separators becomes special importance through the imposition of ever more stringent environmental protection regulations that necessitate a drastic reduction in the pollutants carried by the gases leaving gas-washing plants.


Such regulations make it necessary to install high-performance droplet separators that, while generating as little pressure loss as possible, are capable of arresting even the finest droplets, often with a diameter of less than 10 µm . Working closely with plant operators and with scientific institutes, Lechler has developed a variety of droplet separators, which they have proved to be highly successful in many fields of industry:

  • in reducing environmental pollution from existing plants
  • in gas-washing installations
  • in the chemical industry
  • in the woodpulp industry
  • in air-conditioning and ventilation systems
  • on offshore rigs
  • in cooling towers and evaporative condensers
  • wherever finest droplets must be effectively separated out of vertical gas streams

As each of these applications has individual requirements, Lechler's Droplet Separator Systems are customized solutions.

Custom-made Droplet Separator Systems

It is necessary to the design and planning of Droplet Separators to have a good understanding of the process in which the Droplet Separator will be incorporated as well as a thorough understanding of the function and performance of the various separation systems. It is of great importance when designing a Droplet Separator to have an understanding of how droplets are generated and of how they are transported in a flow of gas.

We can honestly say that we know as much or more in this respect than any other, for we have been engaged in the detection, measurment and definition of droplets for more than 140 years. It is not without reason that Lechler Droplet Separators have become such essential alements in almost every field of process engineering.

The droplet separators can be produced in a wide variety of designs in the materials stainless steel, plastic or aluminium. They are supplied as ready-to-install components or individual lamellae.
