High-performance trickle fill installations allow a completely new way of thinking about the design of film installations. The plastic is used only where it really makes sense - not a water-scarce areas - also a water film which flows around both sides - combined with droplet cleansing and thus the highest cooling interface.

High thermal performance (through water film formation) at the lowest pressure loss (less than vertical offset channel).The material thickness of 1.5-2 mm is many times higher than fill inserts.

The NB 25 product design offers a stability class. Particular attention is paid to environmental compatibility (solvent-free), simple and rapid processing (mechanical) by means of stable assembly technology as well as adhering to every fire protection requirement.

Due to the open vertical grid structure with free volume of > 97%, these trickle fill installations are particularly suitable for highly contaminated as well as highly polluted water quality. Areas of application are cooling towers, agricultural and exhaust air applications.
