Clean, Dry Compressed Air

K-MT 1 - 8

Adsorption Dryers
Whether a compressed air user wants to
control the growth of micro-organisms
(essential for direct and in-direct contact
applications in the food, beverage &
pharmaceutical industries), ensure
air used for critical applications /
instrumentation is free from water
contamination or has external piping
where low ambient temperature can
cause condensation, adsorption dryers
are the go to dryer technology.
There are many different adsorption dryer
technologies available and whilst they all
reduce water from the compressed air in
the same way, they differ in the way they
regenerate the desiccant material.

Heatless Adsorption Dryers

The simplest and most common method
used to regenerate the adsorbent
desiccant material is the ‘heatless’
method (so called as it does not use heat Advantages
for desiccant regeneration). • Parker K-MT dryers provide a constant outlet dewpoint in accordance with
ISO8573-1 classes 1, 2 or 3 for water vapour
Using a proportion of the clean, dry
process air for regeneration, heatless • Parker K-MT dryers provide an outlet dewpoint which inhibits the growth of
dryers typically have the lowest capital micro-organisms (allowing their efficient reduction using filtration)
costs of all adsorption dryer types (due to • Parker K-MT dryers use clean, dry purge air for regeneration, eliminating any
the simplicity of the heatless design). risk of damage to the adsorption bed or re-contamination of the downstream
Being very robust and having fewer compressed air
components, they typically have the • No heat is used for regeneration; therefore, no insulation is required and loss of

large, whereas the more complicated display and dewpoint switching Energy Saving Technology
regeneration methods are often only
available for higher flow rates due to cost
and complexity of the designs.

Product Selection & Correction Factors

For correct operation, compressed air dryers must be sized using for the maximum (summer) inlet temperature, maximum (summer)
ambient temperature, minimum inlet pressure, required outlet dewpoint and maximum flow rate of the installation.

To select a dryer, first calculate the MDC (Minimum Drying Capacity) using the formula below then select a dryer from the flow rate table
above with a flow rate equal to or above the MDC.

Minimum Drying Capacity = System Flow x CFIT x CFAT x CFMIP x CFOD
