Additive Eductor

Additive eductors are used, for example, to introduce PVC additives into reactors and condensers with the aid of steam. This can prevent polymer deposits during PVC production.

Sizes: DN 40 (1,5″) to DN 100 (4″)


  • Our additive eductors are made of stainless austenitic steel (AISI 316Ti)

  1. Starting the steam supply heats the nozzle in the eductor.
  2. In the next step, the additive is metered into the motive steam using an atomizer nozzle and mixed.
  3. The steam serves as a transport medium for the additive, which is introduced into the reactor through a pipeline.
  4. The mixture then condenses on the reactor wall, leaving a protective film there.
