Desiccant Rotors International (DRI) has spent over 200 "man-years" of research in the field of rotors, to create the ideal honeycomb / fluted media, best suited to your application. Once we know your requirement, our scientists and engineers can work out the most efficient and economical design for your need.


'DRI' honeycombs Nature perfected

The DRI honeycomb / fluted media is inspired by the work of art in nature….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. Typically, the ceramic fibre paper 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 low substrate mass, high catalyst loading, and low heat carryover.


This is a major advantage over the conventional cordierite honeycomb carriers. The DRI fluted media can easily be used up to 8000C 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.

Typical substrates :
  • Ceramic fibre paper
  • Metal silicate loaded paper
  • Kraft paper
  • Glass fibre paper
  • Active carbon paper
  • Plastic sheet
  • Aluminium foil
  • Gold foil
  • Tissue paper
  • Stainless steel foil
 

Typical desiccants / catalysts and chemicals

  • Metal silicate (several options)
  • Hydrophobic zeolites
  • Silica Gel
  • Catalysts (variety)
  • Zeolites / molecular sieve (s)
  • Noble metals

Bringing them together ... Some methods
We have not only mastered the art of creating honeycombs, but also science of combining the substrates with chemicals, using various processes, such as :

  • Coating the fluting material
  • Impregnating the substrate
  • Pre-loading (e.g. during manufacture of speciality paper)
  • Synthesising ‘in situ’


Our state-of-the-art R & D Lab is very versatile and is regularly used for the following:

 
     
 


To simulate and optimize dynamic enthalpy / energy recovery variables for new product design and development e.g. Rotors & Sensible latent Recovery.

  • To standardize/establish ideal performance curve for fluted media desiccant products i.e. ERV’s, HRW etc.
  • To standardize /establish ideal performance curve of fluted media (honeycomb) products.
  • To evaluate and certify the performance of desiccant (honeycomb) wheel rotor.
