Each project calls for a special design and arrangement of droplet separators. The design, construction, and the manner in which the baffles are arranged in a Lechler mist eliminator depend entirely on the requirements, details and specification of the project. Lechler does not offer a standard "off the shelf" solution but designs and assem- bles the most suitable separator for each specific requirement utilising standard elements of the Lechler unit construction system.
