RTO Ceramic Media Heat Exchange Media Options

The ceramic heat exchange media is a key element to every RTO installed in the market place.  With literally hundreds of ceramic media types available the selection of the proper type can be critical to the proper operation and ultimately environmental compliance from a regulatory stand point.

In general, there are two main types of heat exchange media:  random packing saddles and monolith block.  Each offers unique advantages and disadvantages that must be evaluated.

Random Packing Saddles

One of the first types of ceramic media used in RTO applications and is still used today in certain applications.  The advantage to this type of ceramic media is that it typically regarded as having good resistance to plugging from particulate that may be present in the air stream.  This is because air moving into the media beds moves slowly and randomly through the heat exchange media looking for open airways.  If it meets resistance due to plugging it will redirect itself looking for another open airway.

The disadvantage is that an RTO designed with random packing media needs a fairly large area to maximize its thermal efficiency properties.  Typically, a +95%TER saddle RTO will require 8’ depth of random packing saddles.  This 8’ of depth contributes to high-pressure drops associated with the RTO fan that moves air through the system.

RTO Ceramic Honeycomb

Over the years a great deal of attention has been focused on the advancement of ceramic medias for use in RTOs with the intent of reducing utility consumption, fuel, and electricity.  This focus led to the development of a monolith ceramic media that allowed for linear flow air paths and also provided a higher volume of heat exchange media in a relatively small area.  On average a monolith block RTO will be one-third to one-half of the size of a random saddle RTO.

The other advantage of the monolith block is that to achieve the +95%TER only 5 feet of media was required thus significantly reducing the brake horse power (bhp) of the RTO fans.
