High-performance trickle fill installations are characterised by their high mechanical strength.

This strength is determined by two special factors, on the one hand by the mechanical and extremely stable connection technology and on the other hand by the specially vertical fill design.

The OS 21circular fill can be produced in almost any strength class, so that, depending on the customer's requirements, the optimum design is available to suit the application.

Due to the optimised fill design with a free volume > 97%, these fills can be used for contaminated water qualities.
