Holmen logo

The Holmen range of Pellet Durability Testers offer a fast and reliable method of testing PDI or Mechanical Durability. From feed pellets to wood pellets, either manual or automatic testing. Holmen provides a solution suitable for your mill.

The Insectomat provides a quick and accurate method for testing wheat, barley and oats for the presence of insects, because early screening and detection at the point of intake can prevent later and potentially costly infestation in stored grain.
