Cooling Tower Trickle Grid Fill VC25 

High-performance VC25 trickle fill installation allow a completely new way of the design of film fill installations. This VC25 fill 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 so as to achieve the highest cooling interface.

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


Particular attention is the environmental compatibility (solvent-free), simple and fast installation by means of assembly technology. In addition, we also could supply the fire protection type to meet with every local fire protection requirement.


The VC25 fill which we developed for processing single lattices are suitable for permanent use as well as for deployment on construction sites under weather protected conditions.

Due to the open vertical-offset grid structure with a free volume of > 97%, these trickle grid fill is particularly suitable for contaminated as well as highly polluted water quality.

Areas of application of VC25 fill are cooling towers, agricultural and exhaust air applications.

This VC 25 Trickle Grid Fill is the popular choice for field-erected or package counterflow cooling towers. Can also be used in the crossflow towers. For use in power plant, refining, chemical, steel, and food processing applications where the water quality is poor. It is also suitable for cooling waters with higher contents of suspended solids, oils and the like.


The cooling fill can by walked upon without temporary boards or the like, it will not be eroded from the sprayed upon cooling water and it can be flushed with high pressure water jets.
