Liquid Distributors and
Redistributorsr

in Metal and Plastic

Standard liquid distributors are usually used for liquid loads in a range of 5 to 80 m³/m²/h. Their simple design allows short production times and low cost. Various applications in industry require special liquid distributors to ensure
optimal distribution quality, highest wettability, controlled gas flow, low pressure drop, fouling resistance or high operating ranges. For all of the different industrial demands, Raschig has a standardized or customized solutions. The liquid distributor selection matrix below offers a first indication on the liquid distributor for the individual application.
