Our
HLS Series heatless regenerative compressed air dryers are
designed to protect pneumatic equipment and processes from
the harmful and costly effects of compressed air moisture
in low flow applications. The little brother of our highly
recommended HL Series heatless regenerative compressed air
dryer, our HLS Series air dryers provide a low -40° or
-100° F dew point between 55 and 150 SCFM.
Since
there is no external heat source, our HLS Series heatless
regenerative compressed air dryers use a percentage of the
dry air from one tower to regenerate the wet desiccant in
the other tower. This makes the HLS Series compressed air
dryer dependable and easy to monitor while requiring little
maintenance. For these reasons, these compressed air dryers
are ideal for protecting instruments and processes, such
as critical point-of-use applications, laboratory use, paint
spraying, and dust collectors.
The
cycle monitor with LED and remote contact allows immediate
notification of any disruption of the operation cycle. The
controller also features a membrane panel housed in a NEMA
4X enclosure which clearly displays dryer operation with
LED indicators for each step in the cycle sequence. This
allows for a quick and easy way to monitor the performance
of the compressed air dryer.

Lubricated
Compressors - Dryer
must be equipped with proper Van Air pre-filters. These
filters must be drained and maintained as specified.
Desiccant beds should be checked periodically and replaced
if contamination has occured. Failure to do so may result
in hazardous operating conditions and will void the
warranty. An after-filter should be installed downstream
of the dryer to prevent desiccant particle migration.
Non-lubricated Compressors - A particulate
or coalescing pre-filter is recommended to prevent pipe
scale and dust from fouling the dryer. An after-filter
should be installed downstream of the dryer to prevent
desiccant particle migration. |
