'DRI' Honeycombs = Nature

The DRI honeycomb / fluted media draw inspiration from the nature's own work of art - the honeycomb. The honeycomb structure combines the advantages of maximum surface area, least pressure drop, light weight and amazing structural strength. It can be made highly porous due to the nature of construction of the substrate used.

The fluted media, due its porosity, can act host to any desiccant, metal silicates and catalysts in its walls, depending upon its usage, like air drying, VOC removal, etc. Even for applications like NOx removal, excellent honeycombing is possible, to provide a high velocity air passage with a low substrate mass, high catalyst loading, and low heat carryover.

This innovation is a major advantage and sets it apart from the conventional honeycomb carriers. The DRI fluted media can easily be used up to very high temperatures and can take many desiccants and catalysts according to the end usage required.

Endless choices and challenges

Various permutation and combinations of substrates, chemicals, synthesizing processes and design features are possible, depending upon the application.

Bringing them together ... Some methods

We have not only mastered the art of impersonating and recreating nature's wonder - honeycombs, but also the science of combining the substrates with chemicals, using various processes, that include:
